Bulletin Summary
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.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
