| 01-07-30-042H | 2018-05-21. Service bulletin. POWER TRAIN:CLUTCH ASSEMBLY; POWER TRAIN:AUTOMATIC TRANSMISSION:TORQUE CONVERTER; POWER TRAIN. 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. |
