I've tried to do that tranny adaptation reset thing many times and I didn't notice a thing. Someone mentioned on one post that you should hear a tick or something, but I never heard anything. There was absolutely no difference after any of the times I tried it. I've even tried driving like ass and pussy-footed immediately after the reset. and nothing... I never had this off to on gas problem before until just recently.
For me, if I accelerate abruptly from a coast... BAMMM the more gas the harder it hits. It really ticks me off because now I have to drive like a Nancy to avoid it.

I've been searching for the past 2 hours but I can't seem to find anything on tranny software updates for E53's built prior to October 2003. Is there an tranny software update for 2002 4.4i??

Just changed my MAF and cleaned the throttle body hoping that would do the trick. Nope, just wasted my $$. After countless hours of reading threads, I was very confident that the MAF was the problem but I was wrong
