4T40-E Automatic Transaxle

Description:

NOTE: You will use the fluid level screw (2) for diagnosing a transmission fluid leak or for resetting the transmission fluid level after service that involves a loss of fluid.

Fluid Level Diagnosis Procedure

Check the fluid level when the transmission is above 40°C (104°F). This temperature can be reached by performing the following procedure:

1. Park the vehicle on a hoist, inspection pit, or similar raised level surface. The vehicle must be level to obtain a correct fluid level measurement.

2. Place a fluid container below the fluid level screw (2).

3. Start the engine and allow the engine to idle for approximately 5 minutes, or, if possible, drive the vehicle for a few miles to warm the transmission fluid.

4. 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 position.

5. Remove the fluid level screw (2). Because the transmission operates correctly over a range of fluid levels, fluid may or may not drain out of the screw hole when the screw is removed.

Caution: Do not remove the fluid level screw if the transmission fluid is hot. This may cause injury if the fluid drains from the screw hole.

^ If fluid drains through the screw hole, the transmission may have been overfilled. When the fluid stops draining, the fluid level is correct. Install the fluid level screw (2) and torque to the proper specification (12 N.m).

^ If fluid does not drain through the screw hole (2), the transmission fluid level may be low. Add fluid through the fill cap (1) hole in 0.5-liter increments, up to 1.5 liters maximum, until fluid drains through the screw hole. It fluid drains through the screw hole, the fluid level was in the correct operating range. Allow the fluid to finish draining through the screw hole and install the fluid level screw. Torque the fluid level screw to the proper specification (12 N.m).

^ If fluid does not drain through the screw hole after adding a total of 1.5 liters, then the transmission was either underfilled or the transmission is leaking fluid. Inspect the transmission for fluid leaks. Fix any leaks before setting the transmission fluid level.

6. When the fluid level checking procedure is completed, wipe any fluid from the transmission case with a rag or shop towel. Also, check, that the fluid fill cap (1) and the vent tube are properly installed.

Fluid Level Set After Service

After service, set the fluid level according to the following procedure.

1. Add fluid through the fill cap hole prior to adjusting the fluid level. The amount of fluid to add should be based on the table at the end of this procedure.

2. Follow steps 1-4 of the Fluid Level Diagnosis Procedure.

3. Add additional fluid through the fill cap (1) hole in 0.5 liter (1 pint) increments until the fluid comes out through the screw hole.

4. Allow the fluid to finish draining out through the screw hole, then install the fluid level screw (2) and torque the screw to the proper specification (12 N.m).

5. When the fluid level setting procedure is completed, wipe any fluid from the transmission case with a rag or shop towel. Also, check that the fluid fill cap (1) and the vent tube are properly installed.
