Note. The Corvette 4L60-E transmission is not equipped with a fluid dipstick.

SERVICE INTERVALS

Change the automatic transmission fluid and filter every 50,000 miles if the vehicle is mainly driven under one or more of these conditions

1. In heavy traffic where the outside temperature regularly reaches 32°C (90°F) or higher.
2. In hilly or mountainous terrain.
3. Uses such as high performance operation.

If the vehicle is not used under any of these conditions, change the fluid and filter every 100,000 miles.

CHECKING FLUID LEVEL & CONDITION

Note. The transmission fluid may darken with normal use and does not always indicate contamination or oxidation.

1. Start the engine and allow the engine to idle until the transmission fluid temperature has reached 30-50°C (86-122°F). Depress the brake pedal and move the shift lever through the gear ranges, pausing a few seconds in each range. Return the shift lever to the PARK range. Raise the vehicle on a hoist. The vehicle must be level with the engine running and the shift lever in the PARK range. Remove the transmission plug. (Scheme 115) Check the fluid color. If necessary, use a small screwdriver as a dipstick. Is the fluid color clear red or light brown with no burnt odor? If so, go to step 4. If not, go to next step.
2. Does the fluid have a burnt odor or a dark brown color? If so, go to step 8. If not, go to next step.
3. Does the fluid have a cloudy or milky appearance? If so, go to step 7. If not, go to step 8.
4. Check the fluid level. The fluid level should be even with the bottom of the threaded plug hole. Is the fluid level low? If so, go to next step. If not, go to step 11.
5. Add appropriate automatic transmission fluid in increments of 0.5L until the fluid drains from the plug hole. See «RECOMMENDED FLUIDS»(/chevrolet/corvette/c5-1997-2004/remont/automatic-trans/#automatic-transmission-servicing__recommended-fluids). Did you add more than 1.5L to the transmission? If so, go to next step. If not, go to step 11.
6. The transmission may have a leak. Inspect as necessary. Was a transmission fluid leak found? If so, go to step 9. If not, go to step 11.
7. The transmission fluid is contaminated with engine coolant. Repair or replace the transmission cooler in the radiator. Is the transmission cooler repair complete? If so, go to step 9.
8. Drain the fluid by removing the bottom pan. Check the bottom pan for any excessive debris. Was excessive debris found? If so, go to next step. If not, go to step 10.
9. Repair the transmission if required (in some cases, overhaul may be required). See appropriate OVERHAUL article in AUTOMATIC TRANSMISSIONS. Flush the transmission oil cooler and pipes and check flow. See «OIL COOLER FLUSHING»(/chevrolet/corvette/c5-1997-2004/remont/automatic-trans/#automatic-transmission-servicing__oil-cooler-flushing) and «TRANSMISSION & OIL COOLER FLOW CHECK»(/chevrolet/corvette/c5-1997-2004/remont/automatic-trans/#automatic-transmission-servicing__transmission-oil-cooler-flow-check) under LUBRICATION. Add enough fluid to bring the fluid level to the bottom of the threaded plug hole. Start the engine and allow the engine to idle until the transmission fluid temperature has reached 30-50°C (86-122°F).

Scheme 122

Initial Flush

1. Turn the flusher water supply valve (1) to the ON position and allow water to flow through the oil cooler and pipes for 10 seconds to remove any remaining transmission fluid. (Scheme 123) If water does not flow through the oil cooler and pipes, the cause of the blockage must be diagnosed and the plugged component must be repaired or replaced. Continue with the cooler flushing and flow check procedure once the blockage is corrected.
2. Turn the flusher water supply valve (1) to the OFF position and clip the discharge hose (5) onto an appropriate container with a lid, to avoid splashback. (Scheme 124) Turn the flusher water supply valve (1) to the ON position and depress the trigger (8) to mix cooler flushing solution into the water flow. (Scheme 121) Use the clip provided on the handle to hold the trigger (8) down. The discharge will foam vigorously when the solution is introduced into the water stream.
3. Flush the oil cooler and pipes with water and solution for 2 minutes. During this flush, attach the shop air supply of 120 psi (825 kPa) to the flushing system feed air valve (2) located on the flusher for 3-5 seconds at the end of every 15-20 second interval to create a surging action.
4. Release the trigger (8) and turn the flusher water supply valve (1) to the OFF position.

Scheme 123

Scheme 124

Back Flush

1. Disconnect both hoses from the oil cooler pipes and then connect them to the opposite oil cooler pipe. This will allow the oil cooler and pipes to be back flushed. Repeat steps 2 and 3 of the INITIAL FLUSH procedure. Release the trigger (8) of the flusher and allow water only to rinse the oil cooler and pipes for one minute.
2. Turn the flusher water supply valve (1) to the OFF position and turn OFF the water supply at the faucet. Attach the shop air supply to the flushing system feed air valve (2) on the flusher, and blow out the water from the oil cooler and pipes. Continue until no water comes out of the discharge hose (5).
