So about 2 months ago my Transmission went out on a road trip It hat 165,000 miles on it, I had some clutch packs burn up on me and was building up heat way to fast and was done for, So I had it towed to a shop and had them put a brand new Transmission in it instead of rebuilding my old one, I got a 3 year/ 100,000 mile warranty with GM. Anyways, I notice with my new transmission that 1st gear going into 2nd is kinda a rough shift and sometimes slips or revs up into 2nd, but 2nd to 3rd and 4th are all smooth as butter and cant even tell it shifts. Just wondering, did my new transmission need tuned to my PCM? I even asked the shop if they had programmed it or if it even needed programmed, He told me no, that it shouldnt be a problem. Just kinda irritates me I spent $2500 with labor for a new tranny that jolts into 2nd gear, I also notice that sometimes if i give it a lot of gas from 1st to 2nd it shifts smooth, but if i dont give it very much throttle it kinda just shifts roughly into 2nd. Any Idea's? I really appreciate it guys! Thanks, Alec
