Automatic Transmission Diagnosis and Maintenance Quiz

Study Notes

Identifying the transmission/transaxle can be challenging and requires checking service information.
A stall test is performed to verify the proper operation of the torque converter.
To locate a leak from an automatic transmission/transaxle, perform a visual inspection and use dye testing if necessary.
The torque converter clutch may not be applying due to a fault in the computer sensors, wiring, or the TCC solenoid.
Range charts indicate which holding device is used for each gear selection in a vehicle.
Pressure testing involves connecting a pressure gauge to pressure taps located on the outside of the automatic transmission/transaxle.
Separating the torque converter from the engine drive flex plate can help diagnose vibrations.
Using a scan tool is helpful when diagnosing automatic transmission problems.
Proper procedures should be followed when removing the pan from the transmission/transaxle.
Many possible causes of poor performance or sluggish acceleration exist besides a fault with the automatic transmission/transaxle.
Steps to remove and inspect automatic transmission fluid (ATF) pan
Use protective clothing and avoid contact with hot fluid
Inspect pan for excessive friction material and wear metals
Use a magnet to check for steel particles indicating severe wear
Filter replacement is recommended and can cause problems if not done correctly
