Like it says, I have an 05 2wd 4.2L came stock with 3.42s . I with 34s it just wasn't working, so I found a complete rearend with 4.10s and PCMofNC do there deal, put it in and test drove and saw right away it was awesome, then the ABS & BRAKE lights came on the cluster , also the cruse control will not even try to work. I went by 2 local GM dealers to see if they could do a relearn or whatever and tell it it had 4.10 gears, well they almost freaked out on me saying that it was illegal !! haha and the GMC dealer said even if it wasn't "illegal" they probably wouldn't be able to do it because it was a chevy and not a GMC ! So at this point I'm just dumbfounded by the excuses I was getting....so if anyone could point me in the right direction please let me know. Thanks in advance!
