What the numbers on a ZF 8HP actually mean, how Mopar's 845RE and 850RE naming maps across, and which ASE conversion kit fits each donor transmission.
Your fresh 8HP swap shifts badly because the controller has not learned it yet. What clutch adaptation is, why the factory relearn procedure does not apply to a swap, and how to break one in properly.
A complete step-by-step installation guide for the ASE CD009 front mount shifter relocation, covering the two modifications — shortening the side detent plungers and clearancing the rear of the case — that account for nearly every reported install failure. Applies to both CD and JK transmissions.
