    Alright y’all, I’ve got a wall n don’t know wth to do. So I’ve chased the wires on the trans and found nothing bent broken or frail.

    Hey all, I've got a 2003 LB7 Duramax with 240,000 miles and a Bully Dog tuner throwing p0700 and u2106. I know the p0700 is a MIL request from the TCM and the u2106 is lost communication with the TCM but I don't want to sink money into a new TCM if there's a cheaper fix. The truck shifts hard...

    Bare with me it’s a bit lengthy. Have a 2010 LMM that’s been giving me TCM and ECM communication codes. Traction control and ABS lights come on and at higher speeds it will hesitate to shift. Took it to a shop the first time and they found a blown fuse (unrelated) and a bad wheel speed sensor...
