hey guys, I recently changed the tranny on my 99 v6 to a 02 tranny. when i brake, right before the car stops i feel like this pull like it pulls back then it stops like the gears are jumping. My friend said that because i have 20" rims that my tranny has to be adjusted to that dimension. Ive put about 1200 miles on the car since i changed the tranny and have been running it like that, hasnt given me any problem,yet. is this bad or should i leave it?Opinions? Plus about how much would it run me to adjust it?
