How long does it take for a Allison Transmission to relearn?
Re-learn normally takes up to two hours (this time can be significantly reduced by using Tech2 or PC based Allison software to clear the memory and place the TCM in the ‘fast learn’ mode). During the relearn there will probably be some clunks, bumps and/or short flares, especially during the 3-4 shift.
