LUBRICATION

CAUTIONUse the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force, and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Note. The 4T40-E is not equipped with a dipstick.

3T40

Check transmission fluid level at every engine oil change. Transmission fluid should be changed under normal operating conditions at 100,000 miles. Under continuous extreme operating conditions (trailer towing, heavy city traffic with ambient temperature more than 90°F (32°C) or delivery service), fluid and filter should be changed every 50,000 miles.

4T40-E

This transaxle is not equipped with transaxle fluid dipstick. Check transmission fluid level only when leaks have occurred. Under continuous extreme operating conditions (trailer towing, heavy city traffic with ambient temperature more than 90°F (32°C) or delivery service), fluid and filter should be changed every 50,000 miles.

CHECKING FLUID LEVELS

CAUTIONDO NOT overfill. When transaxle is cold, fluid level will rise from minimum level to maximum level on dipstick as transaxle reaches normal operating temperature.
CAUTIONIf vehicle has been driven for an extended period of time at high speeds, in city traffic, in hot weather or if vehicle has been pulling a trailer, an accurate fluid level reading cannot be made until vehicle has been parked and ATF is allowed to cool for about 30 minutes.
  1. Start engine. Operate vehicle for at least 15 minutes or until operating temperature is reached. With engine at idle and vehicle on level ground, move gear selector lever through all ranges, ending in Park.
  2. Remove transaxle dipstick, wipe clean and fully reinsert into filler tube. Remove dipstick again, and inspect fluid level. Fluid level should be between ADD 1 PT. mark and FULL HOT mark, between COLD and HOT mark, or within cross-hatched area on dipstick, depending on dipstick.
CAUTIONThe engine must be running when the transaxle fluid fill plug is removed, or excessive fluid loss will occur. Transmission fluid may be hot. Since the actual fluid level is unknown, stand clear when removing the fill plug. Have a container ready to capture any lost fluid. DO NOT turn the engine off with the fill plug removed, as you can be injured by hot transmission fluid being expelled out of the oil fill opening.

Note. The 4T40-E is not equipped with a dipstick.

  1. Fluid level must be checked with transaxle temperature of at least 104°F (40°C). To obtain proper temperature, run engine at idle for 3-5 minutes. Shift through each gear range, holding in each range for 3 seconds.
  2. Place gear selector in Park. Leave engine running. Raise and support vehicle. Place oil drain pan below oil check plug. Oil check plug is located in center of transaxle above pan rail, on torque converter side. (Scheme 150) Remove oil check plug.
  3. Oil level should be even with bottom of oil check plug hole. If fluid does not drain from hole, add fluid until fluid starts to pour from hole. Tighten oil check plug to specification. See «TORQUE SPECIFICATIONS»(/chevrolet/cavalier/iii-1995-2005/remont/automatic-trans/#automatic-transmission-servicing__torque-specifications).

OIL COOLER FLUSHING

Note. DO NOT use solutions that contain alcohol or glycol. Use of solutions that contain alcohol or glycol may damage flushing equipment, oil cooler components and/or transaxle components.

CAUTIONFlushing Solution (J-35944-22) is environmentally safe, yet powerful enough to cut through transmission fluid to dislodge any contaminants from the cooler. The safety precautions on the label regarding potential skin and eye irritations associated with prolonged exposure are typical precautions that apply to many similar cleaning solutions. It should be noted that according to General Motors, use of other non-approved fluids for cooler flushing can have an adverse reaction to the seals inside the transaxle.

Preparation

  1. After the repair or replacement transaxle is installed in the vehicle, do not reconnect the oil cooler pipes.
  2. Remove the fill cap (9) on the Transmission Oil Cooler and Line Flusher (J-35944-A) and fill the flusher tank (4) with 20-21 oz. (0.6L) of flushing solution using the measuring cup (6). DO NOT overfill. Install the fill cap (9) on the flusher and pressurize the flusher tank (4) to 80-100 psi (550-700 kPa), using the shop air supply at the tank air valve (9). (Scheme 155)
  3. Connect the flusher discharge hose (5) to the oil cooler return pipe (top connector). This may require (J-35944-600). Clip the discharge hose (5) onto the oil drain container. Attach the flusher to the undercarriage of the vehicle with the hook provided, and connect the flushing system feed supply hose (3) from the flusher to the oil cooler feed pipe (bottom connector). This may require (J-35944-600). (Scheme 156)
  4. With the water supply valve (1) on the flusher in the OFF position, connect the water supply hose (7) from the flusher to the water supply at the faucet. (Scheme 155)and (Scheme 156). Turn ON the water supply at the faucet.

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 157) 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 158) 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 155) 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.

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).

TRANSAXLE & OIL COOLER FLOW CHECK

  1. Disconnect both hoses from the oil cooler pipes. Connect the oil cooler feed pipe (bottom connector) to the transaxle and the return pipe (top connector) to the discharge hose (5). This may require J-35944-600. Clip the discharge hose (5) onto the empty oil drain container. (Scheme 158)
  2. Confirm the transaxle is filled with ATF. See «CHECKING FLUID LEVELS»(/chevrolet/cavalier/iii-1995-2005/remont/automatic-trans/#automatic-transmission-servicing__checking-fluid-levels). Start the engine with the transaxle in PARK range and run for 30 seconds. A minimum of 2 qts. (1.9L) must be discharged during this 30-second run time. If fluid flow is greater than 2 qts. (1.9L) in 30 seconds, go to next step. If fluid flow is less than 2 qts. (1.9L) in 30 seconds, go to step 4.
  3. Remove the discharge hose (5), reconnect the cooler feed and return pipes to the transaxle and refill the unit to the proper fluid level. Inspect the transaxle oil cooler pipe connections at the radiator, the auxiliary cooler (if equipped) and the transaxle for leaks.
  4. Disconnect the oil cooler feed line at the radiator. Connect the discharge hose (5) to the cooler feed line. Clip the discharge hose (5) to the empty oil drain container. (Scheme 158) Start the engine with the transaxle in PARK range and run for 30 seconds. A minimum of 2 qts. (1.9L) must be discharged during this 30-second run time. Perform the following according to the flow rate: Insufficient feed flow: Inspect the transaxle. Sufficient feed flow: Inspect the oil cooler return pipe and the oil cooler (and auxiliary cooler, if equipped).
