About the GMC 1500-Regular-Cab Transmission Computer (TCM/TCU/TRANSMISSION-CONTROL-MODULE)

The Transmission Computer (TCM/TCU) controls automatic transmission shifting, torque converter lockup, and gear selection. A failing TCM causes harsh shifting, stuck gears, limp mode, and transmission warning lights. The Transmission Computer (also known as TCM, TCU, TRANSMISSION-CONTROL-MODULE) is a critical component for your GMC 1500-Regular-Cab.

Signs of Failure

Know when your 1500-Regular-Cab transmission computer needs replacement:

  • Harsh or delayed shifting

  • Limp mode / failsafe mode
  • Check engine light with transmission codes
  • Transmission slipping
  • Won't shift into overdrive
  • Erratic shifting patterns
  • No reverse gear

Replacement Info
