None of it actually... i have a DHP pcm on mine, other than intake its mostly stock and it doesnt do any of that, the shifts are firmer but i cant feel it downshift at a stop and everything on my car still works.... mines a 99gtp

okay. yeah mines a 2001. my tranny is fine. so the computer can actually cause that then with the tranny? i know the pcm is causing my cruise control to not work.
