Anyone know if there is a PCM update for shifting? My trucks 1-2 shift has a crappy layover feel and i have had an odd clunk/shudder or 2 simply driving down the freeway. Any info? truck has 50k on it.
the hardness isn't so much a problem as it is a byproduct of Ford Engineers.
The TCM is intentionally programmed to shift harder when tranny temps are colder. This is done to save on wear/tear of the tranny.
Unfortunately, they went a bit too firm. The TSB addresses this. Do you ever notice the problem when the temperatures are warmer (ie: summer)?
