Diagnostic board
Common GM Trucks & SUVs transmission problems we see
GM has used several transmissions across these trucks, and knowing which one you have helps us pinpoint the problem fast. Whatever your truck is doing, our free diagnostic tells you whether it's a simple repair or something more, before you spend a dollar. Many issues, especially on older 4L60E trucks, are repairable without a full replacement.
4L60E slipping (older trucks)
Worn 3-4 clutches and torque-converter issues; a broken sunshell can cause loss of 2nd, 4th, and reverse.
6L80 shudder (2009+)
Torque-converter shudder, valve-body wear, and a cracked 1-2-3-4 clutch housing.
8L90 harsh shifts (2015+)
Low-speed shudder often traced to valve-body issues.
10L80 rough downshifts (2020+)
Frequently addressed with calibration updates, sometimes internal work.
Whatever your vehicle is doing, our free diagnostic tells you whether it's a simple repair or something more.
