01-07-30-042H2018-05-21. Service bulletin. This information was created to inform the technician that the 2-3 upshift and the 3-2 downshift clunk is caused by the releasing of the 2-4 band and application of the 3-4 clutch assembly during an upshift. Also during a 3-2 downshift, the releasing of the 3-4 clutch during the application of the 2-4 band, can cause torque reversal down the output shaft creating a clunk. This is a normal condition.

If the clutch system fails, the clutch pedal may not return if depressed. If the clutch pedal does not return, it may be possible to start the vehicle when the transmission is in any gear. This could result in unexpected vehicle movement when the engine is started.
