4T40E Fluid Level Checking and Fill Procedure
The fluid level screw is intended to be used for diagnosing a transaxle fluid leak or resetting the transaxle fluid level after service that involves a loss of
fluid.
Inspect
The fluid level should be checked when the transaxle is near 40° C (104° F). A vehicle at room temperature can be brought to 40° C (104° F) by
performing the following procedure.
Caution:
Removal of the fluid level screw when transaxle fluid is hot may cause injury. Use care to avoid contact with the fluid and to avoid transaxle fluid
splashing on to the exhaust pipe.
The engine must be running when the transaxle fluid level screw is removed, or excessive fluid loss will occur. Transaxle fluid may be hot. Since the
actual fluid level is unknown, stand clear when removing the fluid level screw. Have a container ready to capture any lost fluid. DO NOT TURN THE
ENGINE OFF WITH THE FLUID LEVEL SCREW REMOVED AS YOU CAN BE INJURED BY HOT TRANSAXLE FLUID BEING EXPELLED
OUT OF THE FLUID CHECK HOLE.
1.
Let vehicle idle for three to five minutes with accessories off.
2.
Apply brake.
3.
Move shift lever through all gear ranges, pausing three seconds in each range.
4.
Place shift lever in Park.
Important:
Vehicle must be kept level on the hoist.
5.
Raise vehicle on hoist. Refer to "General Information".
6.
Place oil container under fluid level screw.
7.
Remove the fluid level screw with engine running at idle.
8.
Fluid level should be at the bottom of fluid check hole. Because the transaxle operates correctly over a range of fluid levels, fluid may or may not
drain out of the fluid check hole when the fluid level screw is removed. If fluid drains through the fluid check hole, this transaxle may have been
overfilled. When fluid stops draining, the fluid level is correct and the fluid level screw may be installed. If fluid does not drain through the fluid
check hole, the transaxle fluid level may be low. Proceed to Adding Transaxle Fluid.
9.
Install fluid level screw.
