1996 Corvette Overview

The 1996 model year would mark the final year of both the C4 and the Generation II small block engine that powered it.  As such, Chevrolet was prepared to commemorate its departure by offering two special edition Corvettes, both of which would feature an upgraded version of the LT1 power plant.  Denoted as the LT4, the 330-horsepower engine would be showcased in both the Collectors Edition Corvette and a limited edition Grand Sport Corvette.

1996 LT4 Engine
The 1996 LT4 Engine was used in both the Collector’s Edition Corvette and the Grand Sport Corvette.

The LT4 engine featured a number of enhancements over its LT1 counterpart.

To start, the LT4 received newly designed aluminum heads that featured taller ports and bigger valves; 2.00-inch intakes and 1.55 inch exhaust.  Each of these valves had hollow stems that were specially designed to save weight.

They each received special oval-wire springs that could handle increased lift without binding.  To help increase the LT4’s valve lift, Chevrolet employed the Crane Company to provide higher ratio (1.6:1) roller rocker arms.

Revised lift specs called for 0.476 inch on the intakes and 0.479 inch on the exhaust.   In addition, Cam duration was increase from 200 degrees to 203 degrees on the intake side and 207 degrees to 210 degrees on the exhaust side.

Other improvements that were developed solely for use on the LT4 included a freer-flowing intake (which featured taller ports to match the heads), a roller-type timing chain, and a compression increase to 10.8:1, which was a noted increase over the 10.4:1 compression found on the LT1.

Additionally, the LT4’s crankshaft, camshaft, water-pump, drive gear, and main bearing gaskets were all improved upon to bolster horsepower, while premium head gaskets were installed to deal with the extra compression.  While the LT4 shared distinct components with the LT1 – such as a newly designed throttle body, the LT4’s 330 horsepower was a marked improvement of 30 horsepower over the LT1.

It was for this reason that the LT4 engine was specified for the multiple special edition Corvettes that year.

1996 Collectors Edition Corvette
1996 Collectors Edition Corvette

The Special Edition Corvette, which included a special Sebring Silver paint color, 5-spoke matching alloy wheels with special “collector edition” wheel cap centers, perforated sport seats accentuated with “Collector Edition” embroidery, black brake calipers with “Corvette” lettering, and a special trim package featuring chrome “Collector Edition” badges, the 1996 Collector Edition Corvette was solely designed to help honor the end of the C4 era.  It would be made available to consumers as both a coupe and a convertible.

Collectors Edition Corvette
The Collectors Edition Corvette received a specialized hood ornament (as well as other unique trim markings).

If the Special Edition Corvette was a welcome addition, the limited-edition Grand Sport was nothing short of a game-stopper.

Priced at an additional $3250  for the coupe or an additional $2880 for the convertible, the Grand Sport package included exclusive Admiral Blue paint and featured a single white stripe that ran the length of the body as well as two red accent stripes (also known as “Sebring Stripes”) on the driver side front fender.  This unique paint scheme was deliberately developed by GM to pay homage to the classic Corvette Grand Sport Racer of the 1960’s.

The coupe used ZR-1 wheels and tires – P275/40ZR17s in the front and P315/35ZR17s in the rear.  The convertible used P255/45ZR17s in the front and P285/40ZR17s in the rear.  Unlike the ZR-1, which showcased a wider backend, the Grand Sport featured rear render flares to cover the wider back tires.

1996 Corvette Grand Sport
The 1996 Grand Sport features a single white stripe and two red “Sebring” stripes.

The Grand Sport’s interior upholstery was offered either in an all black or a sporty red/black combination, and all of the Grand Sport interiors featured a specialized embroidered headrest which featured the Grand Sport emblem.  All Grand Sports –both coupes and convertibles- were equipped with a six speed manual transmission.  Likewise, all Grand Sports were equipped with the newly revised LT4 5.7 liter small-block V-8 engine.  When ordered with the Grand Sport model, the engine received a special “dress” kit that included bright red paint and red ignition wires.  In all, Chevy built 1,000 Grand Sports, and each was given a special, sequential serial number.

Although the LT4 engine was included as part of every special edition Corvette, it was not limited to the Grand Sport or the Collector’s Edition Corvette.  Any Corvette built in 1996 could be ordered with the LT4 engine (for an additional $1450).  Since the new LT4 engine redlined at 6,300 rpm (700 rpm more than the LT1 engine), models equipped with the LT4 engine included a special 8,000 rpm tachometer instead of the standard 6,000 rpm tachometer.

Despite its improved horsepower over the LT1 engine, the LT4 was not considered a showstopper for many automotive reviewers that year.  The fact remained that while the LT4 produced an extra 30 horsepower than the LT1, there was no notable difference in acceleration.  In fact, both the LT1 and LT4 equipped Corvettes ran similar 0-60mph times.  Another noted complaint of the LT4 engine was the fact that, because it lacked an engine oil cooler, it tended to overheat at sustained top speeds of around 186 miles per hour.

Further it was noted that the larger tires actually inhibited the Grand Sport’s ability to launch quickly from a standing start.  At the same time, the tires were also recognized for improving the Grand Sports cornering abilities, although it was determined that they also caused excessive over-steering during extreme handling situations (while at high speeds).

1996 Corvette Grand Sport
The Corvette Grand Sport rear end – note the specially painted 5-spoke wheels and special fender flares (the latter of which was developed to accommodate the larger rear wheels/tires.

Beyond the engine, other revisions were made to the entire Corvette line for 1996.  The standard four-speed automatic transmission received a number of minor revisions which resulted in better shift quality.  Additionally, the introduction of new torque converters promised greater and prolonged durability.

Selective Real Time Damping was introduced to replace the previous Selective Ride suspension option. Available under option code RPO F45, the Real Time Damping suspension calculated the optimal damping mode for its custom shock absorbers to maintain ride and handling quality via data that was gathered from individual sensors at each of the four wheels.  This system could alter the load level/resistance of each shock individually, and it made these adjustments at intervals of once every 10 to 15 milliseconds, which translates roughly into approximately 1 (one) foot of road traversed when travelling at a speed of approximately 60 miles per hour.

After being absent for five years, the Z51 Handling Package returned to the options list for the 1996 Corvette coupes.  The option once more offered Bilstein shocks, unique front and rear springs, bushings and stabilizers, and 9.5 inch-wide, 17 inch wheels with P275/40ZR17 tires.  When ordered with an automatic transmission, a 3.07:1 axle ratio was specified.   As with before, the Z51 package was criticized as generating too harsh a ride, especially on roads that required even minor repair.  However, it was agreed that the re-introduction of the Z51 option was ideal for drivers who were purchasing Corvettes to race in autocross event.

DID YOU KNOW: Besides the 1990-1995 ZR-1, the 1996 Grand Sport was the only Corvette ever built with a unique Vehicle Identification Number (VIN) sequence, separate from all other regular production Corvettes of that year. The 1996 Grand Sport is readily identified by it’s striking Admiral Blue and Arctic White stripe paint scheme. What many do not know, however, is that the pinstriping on either side of the large white center stripe, is actually a two-color decal, both blue and white. This was done to ensure a perfectly straight line. In early production 1996 Grand Sports models, there is a small area behind the hatch roof (and in front of the panel that attaches to the rear window) that is taped instead of painted. The tape is 1 inch long and about 18 inches wide whose purpose was to eliminate a problem area in the paint booth during manufacturing.

As the model year drew to a close, and the fourth generation Corvette prepared to pass the torch to its successor, it was satisfying to General Motors executives to see a small, but significant, sales increase had occurred.  While few denied the probability that much of it had to do with the introduction of both the Grand Sport and the Special Edition Corvette, the sales numbers had increased to a total of 21,536 units.  Although General Motors noted the increase in sales over the previous year, it was also acknowledged that these increases were still a far cry from the C4’s 1984 introductory model, which had sold more than 51,000 units in its first year of production.  Still, the C4 had evolved from a respectable, if somewhat lackluster sports coupe into a true supercar that continued to push boundaries with each passing model year.  Despite a nearly 70% in cost from 1984 to 1996, Corvette had remained profitable year after year.

Of course, over its 43 year history, the Corvette had seen many evolutions of its former self, constantly transforming peoples’ perception of what a sports car should be.  From the fiberglass bodied 1953Motorama prototype up through the 1996 Grand Sport, the Corvette had evolved into a truly remarkable driving machine – one that was fully capable of holding its own with some of the stoutest competition from around the world.  Now, with the next iteration of Corvette looming on the horizon for the 1997 model year, many were already questioning whether or not General Motors would surpass the C4 with their next generation Corvette.  Little did anyone realize that the technology that had been developed for the C4 would continue to be utilized, making way for a Corvette that was more technologically savvy than anything that been seen before it.

Base Corvette Sport Coupe (1YY07)

  • The base price of the 1996 Chevrolet Corvette Coupe without any optional equipment.
  • A 350 cubic inch, 300 horsepower engine, 4-speed automatic transmission, removable body-color roof panel, a Delco stereo system with cassette, and leather seats were included in the base price.
  • The base engine for the 1996 Corvette was the LT1 small block. In 1996 Corvettes, the engine developed 300 horsepower (net) at 5,000 rpms. The engine torque was rated at 340 lbs. -ft at 3,600 rpm.
  • In 1996, LT1 engines were only mated to automatic transmissions.
  • The automatic transmission had improved friction materials for the intermediate clutch and front/rear bands, improved shift quality and more durable torque converters.

Base Corvette Convertible (1YY67)

  • The base price of the 1991 Chevrolet Corvette Convertible without optional equipment.
  • A 350 cubic inch, 300 horsepower engine, 4-speed automatic transmission, a Delco stereo system with cassette, and leather seats were included in the base price.

1996 Corvette Common Issues

The following list of common issues is intended for individual reference only, and may not reflect the specific issues of every 1996 Corvette. This information comes from a variety of sources including the NHTSA Defects Reports pages. While the intent of this page is to identify the common issues pertaining to the 1996 Corvette (including the Collectors Edition and the Grandsport,) it is not an all-inclusive list and should be used for reference only.

Mechanical Issues

Engine

The Opti-Spark Ignition System has been known to fail on late model C4 Corvettes (those equipped with PFI V8 engines). Failure of the Opti-Spark Ignition System may prevent the vehicle from starting.
Failure of the Ignition Lock Cylinder occurs, though infrequently, preventing the vehicle from starting.
The valve train of the LT4 is somewhat noisy and is one reason that GM made the valve covers of a composite material rather than aluminum or other metal.

The LT1/LT4 engine is also prone to engine oil leaks, most especially around the front and rear of the intake manifold. The manifold was sealed at the ends with RTV rather than gasket material and tended to leak even straight from the factory. Other common areas to check for oil leaks on the engine include: the timing chain cover, the valve covers, the waterpump drive seal, the oil pan, and the front and rear main bearing seals.

The LT1 engine often exhibits a rough idle at start-up, especially after the car has been sitting for an extended period of time. The most probable cause of the idling issue is fouled injectors. In many instances, adding a fuel stabilizer and/or fuel injection cleaner to the fuel tank helps resolve this issue.

Transmission

A transmission leak may occur from the pump body on 4L60-E transmissions due to the pump bushing walking out of the valve body.

It should be noted the ZF6 transmission is somewhat noisy (particularly in neutral with the clutch out)
The transmission is controlled by an electronic control unit. In some instances, this unit is known to fail, causing erratic transmission shifting problems resulting in drivability issues.

Radiator

It is quite common for road debris and trash to get sucked up between the radiator and the A/C condenser, thereby blocking air flow and causing the engine to overheat. This area should be inspected and cleaned out at regular intervals.

Check the underside of the radiator for signs of leaking coolant, the side tanks on the factory radiator are constructed of plastic and may be cracked and leaking on a higher mileage car.

Air Conditioning

Unfortunately, all 1996 Corvettes are subject to one of two A/C problems:

First, failure to be able to raise or lower cabin temperature by pushing on the temperature up/down control buttons on the dash are usually due to a failed A/C Controller Module.

Second, air conditioning blows on the floor or through the defrost vents only but not through the dash vents. These are indications of a bad A/C Program Module.

Low Pressure Tire Warning System (LTPWS)

The sensor bands and sensors are prone to breakage. Additionally, they are unique for each wheel, and GM factory replacement components have become very difficult to find. Cars equipped with this option originally had a sticker on each wheel rim to notify the tire installer about the sensor.

Fuel Pump

Although a common issue on many mid-nineties Chevrolet cars/trucks, the fuel pump on the Chevrolet Corvette is known to fail prematurely. Because of the pumps location in the fuel tank, this repair can be both timely and costly. When replacing the fuel pump, it is generally recommended to replace the entire sending unit as well.

Exterior Issues

Weather Stripping

The weather stripping on all late model C4 Corvettes is not very durable and is a very costly repair. The weather stripping is known to crack, rip, and tear. The weather stripping at the base of the windshield and at the coupe hatchback glass is generally the first, most common portion to fail.

Front Air Dam Spoiler

Because of the low front-end clearance on the Corvette, the front air dam spoiler tends to get damaged even as the result of normal vehicle operation. The front air dam spoiler tends to get scraped up and damaged very easily. Replacement spoilers are available both through General Motors and a variety of aftermarket suppliers.

Roof Panel

Removal of the roof panel may result in extreme vehicle vibration during driving conditions where bumpy, uneven roads exist. This issue has been reported at speeds up to 35 miles per hour.
The front roof line of the Chevrolet Corvette is known to cause visibility obstructions for taller drivers including limiting visibility of traffic lights.

Interior Issues

Driver & Passenger Seats

The first area that most commonly fails are the side bolsters and the seat bottoms, particularly on the driver’s side. The leather on the factory seats is fairly thin and not very durable. Factory original seat cover replacements are no longer available from GM.

The plastic bezel around the seat back release in the back of each headrest are prone to breakage.

Steering Wheel

Steering wheels may exhibit vertical play. If the steering wheel exhibits more than just minimal up and down movement, then the Corvette may have been damaged as the result of prior vehicle operators using the steering wheel as a means of pulling themselves out of the vehicle. The vertical motion indicates that the steering column mounting bolts are probably damaged. While this issue is repairable, it is a very time consuming and expensive repair.

Center Console Cover

The center console lid is commonly known to crack, which is an issue with all C4 Corvettes.

Safety Issues

There have been many incidents reported of the airbags failing to deploy during a head-on collision, resulting in driver injury. The on-board computer does test the air bag system during ignition start. Check for any airbag warning lights on the instrument/dashboard. If the airbag light remains lit, contact a GM Certified service center immediately.

Other Issues

Owners should not be concerned if minor, though visible evidence of overspray (or even blotches) of paint under the hood, particularly in the area around the hood latch pins and receptacles. This was very common on factory production cars of this era and should be expected. In fact, owners should be more concerned if they do NOT see any overspray or spray paint in this area.

There have been many instances of electrical fires reported resulting in damage to the Corvette, often resulting in the total loss of the vehicle. These fires are often attributed to a short in the computer system.

Schedule 2

Follow this maintenance schedule only if none of the conditions from the above maintenance schedule is true.

1996 Corvette Maintenance Schedule
1996 Corvette Maintenance Schedule

The 1996 Corvette has an Engine Oil Life Monitor. This monitor will show drivers when to change their oil – usually between 3,000 miles (5,000 km) and 7,500 miles (12,500 km) since the last oil change.  Under severe conditions the indicator may come on before 3,000 miles (5,000 km).  Never drive your vehicle more than 7,500 miles (12,500 km) or 12 months whichever occurs first, without an oil change.

The system won’t detect dust in the oil.  If you drive in a dusty area be sure to change your oil every 3,000 miles (5,000 km) or sooner if the CHANGE OIL light comes on.  Remember to reset the Oil Life Monitor when the oil has been changed.  See “GM Oil Life System” (at the bottom of this page) for more information on resetting the system.

If you haven’t used your vehicle under severe service conditions listed previously and, therefore, haven’t changed your automatic transmission fluid, change both the fluid and filter.

NOTE:  The services shown in this schedule up to 100,000 miles (166,000 kilometers) should be performed after 100,000 miles (166,000 kilometers) at the same intervals.

Owner Inspection & Service Items

At Each Fuel Fill

NOTE:  It is important for you or a service station attendant to perform these underhood checks at each fuel fill.

Engine Oil Level Check: Check the engine oil level and add the proper oil if necessary.

Engine Coolant Level Check: Check the engine coolant level and add DEX-COOL coolant mixture if necessary.

Windshield Washer Fluid Level Check: Check the windshield washer fluid level in the windshield washer tank and add the proper fluid if necessary.

At Least Once a Month

Tire Inflation Check:Make sure tires are inflated to the correct pressures.
Cassette Deck Service (if so equipped): Clean cassette deck. Cleaning should be done every 50 hours of tape play.

Power Antenna Service: Clean power antenna mast.

At Least Twice A Year

Restraint System Check: Make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired. Have any torn or frayed safety belts replaced.  Also look for any opened or broken air bag coverings, and have them repaired or replaced. (The air bag system does not need regular maintenance.)

Manual Transmission Check (if so equipped): Check the transmission fluid level; add if needed. (See “Manual Transmission Fluid” in the right margin of this page).  Check for leaks. A fluid leak is the only reason for fluid loss. Have the system inspected and repaired if needed

Automatic Transmission Visual Inspection: It is not necessary to check the transmission fluid level during a visual inspection of the actual transmission.  A transmission fluid leak is the only reason for fluid loss. Check for leaks. If a leak occurs, take the vehicle to your Chevrolet dealership service department and have it repaired as soon as possible.

At Least Once A Year

Key Lock Cylinder Service: Lubricate the key lock cylinders.

Body Lubrication Service: Lubricate all body door hinges. Also lubricate all hinges and latches, including those for the hood, rear compartment, console door and any folding seat hardware.  More frequent lubrication may be required when exposed to a corrosive environment.

Starter Switch Check: CAUTION: When you are doing this check, the vehicle could move suddenly.  If it does, you or others could be injured.

Before you start, be sure you have enough room around the vehicle.

Firmly apply the parking brake and the regular brake.

On automatic transmission vehicles, try to start the engine in each gear. The starter should work only in PARK (P) or NEUTRAL (N). If the starter works in any other position, your vehicle needs service.
On manual transmission vehicles, put the shift lever in NEUTRAL (N), push the clutch down halfway and try to start the engine. The starter should work only when the clutch is pushed down all the way to the floor.  If the starter works when the clutch isn’t pushed all the way down, your vehicle needs service.

Brake-Transmission Shift Interlock (BTSI) Check: CAUTION: When you are doing this check, the vehicle could move suddenly. If it does, you or others could be injured.

Before you start, be sure you have enough room around the vehicle. It should be parked on a level surface.

Firmly apply the parking brake.  (NOTE: Be prepared to apply the parking brake immediately if the vehicle begins to move.)

With the engine off, turn the key to the RUN position, but don’t start the engine.  Without applying the regular brake, try to move the shift lever out of PARK (P) with normal effort. If the shift lever moves out of PARK (P), your vehicle’s BTSI needs service.

Steering Column Lock Check: While parked, and with the parking brake set, try to turn the ignition key to OFF in each shift lever position. With an automatic transmission, the key should turn to LOCK only when the shift lever is in PARK (P). With a manual transmission, the key should turn to LOCK only when the shift lever is in REVERSE (R). On all vehicles, the key should come out only in LOCK.

Parking Brake and Automatic Transmission PARK (P) Mechanism Check: CAUTION: When you are doing this check, your vehicle could begin to move. You or others could be injured and property could be damaged. Make sure there is room in front of your vehicle in case it begins to roll. Be ready to apply the regular brake at once should the vehicle begin to move.

Park on a fairly steep hill, with the vehicle facing downhill.  Keeping your foot on the regular brake, set the parking brake.

To check the parking brake’s holding ability: With the engine running and transmission in NEUTRAL (N), slowly remove foot pressure from the regular brake pedal. Do this until the vehicle is held by the parking brake only.

To check the PARK (P) mechanism’s holding ability: With the engine running, shift to PARK (P). Then release the parking brake followed by the regular brake.

Underbody Flushing Service: At least every spring, use plain water to flush any corrosive materials from the underbody. Take care to clean thoroughly any areas where mud and other debris can collect.

Dealership Inspection & Service Items

At Least Twice A Year

Steering and Suspension Inspection: Inspect the front and rear suspension and steering system for damaged, loose or missing parts, signs of wear or lack of lubrication. Inspect the power steering lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc.

Tire and Wheel Inspection: Inspect the tires for uneven wear or damage. If there is irregular or premature wear, check the wheel alignment.  Inspect for damaged wheels.

Exhaust System Inspection: Inspect the complete exhaust system. Inspect the body near the exhaust system. Look for broken, damaged, missing or out-of-position parts as well as open seams, holes, loose connections or other conditions which could cause a heat build-up in the floor pan or could let exhaust fumes into the vehicle.

Radiator and Heater Hose Inspection: Inspect the hoses and have them replaced if they are cracked, swollen or deteriorated. Inspect all pipes, fittings and clamps; replace as needed.  Clean the outside of the radiator and air conditioning condenser.  To help ensure proper operation, a pressure test of the cooling system and pressure cap is recommended at least once a year.

Throttle Linkage Inspection: Inspect the throttle linkage for interference or binding, and for damage or missing parts. Replace parts as needed. Replace any cables that have high effort or excessive wear.  Do not lubricate accelerator and cruise control cables.

Rear Axle Service: Check the gear lubricant level in the rear axle and add if needed.  A fluid loss may indicate a problem. Check the axle and repair it if needed.

Brake System Inspection: Inspect the complete system. Inspect brake lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc. Inspect disc brake pads for wear and rotors for surface condition. Inspect other brake parts, including calipers, parking brake, etc.  You may need to have your brakes inspected more often if your driving habits or conditions result in frequent braking.

GM Oil Life System

Your vehicle has a computer that lets you know when to change your engine oil. This is not based on mileage, but on engine revolutions and engine operating temperature. When the computer has calculated that the oil needs changing, the GM Oil Life System will indicate that a change is necessary. The mileage between oil changes will vary depending on how you drive your vehicle — usually between 3,000 miles (5 000 km) and 10,000 miles (16 000 km) since your last oil and filter change. Under severe conditions, the system may come on before 3,000 miles (5 000 km). Never drive your vehicle more than 10,000 miles (16 000 km) or 12 months (whichever occurs first) without an oil change. Use engine oil meeting the GM Standard GM4718M.

The system won’t detect dust in the oil. So, if you drive in a dusty area, be sure to change your oil and filter every 3,000 miles (5 000 km) or sooner if the CHANGE OIL SOON message appears. Remember to reset the system whenever the oil is changed.

How to Reset the Change Oil Soon Message
To reset the CHANGE OIL SOON message after an oil change, do the following:
1. Turn the ignition to ON and with the engine off.
2. Press the TRIP button so the OIL LIFE percentage is displayed.
3. Press RESET and hold for two seconds. OIL LIFE REMAIN 100% will appear.
