If your shop sees GM front-wheel-drive vehicles like the Traverse, Malibu, or Acadia, you know the 6T70 and 6T75 are regular visitors — often with broken wave plates, slipping gears, or no reverse.

At ACE, we remanufacture 6T70/6T75 units with all known failure points addressed up front. Each build is tested under load, upgraded with modern fixes, and shipped fast so your team stays efficient.

Known 6T70 / 6T75 Failures We Fix

  • 3-5-R wave plate failure causing slipping or no reverse
  • Valve body wear and solenoid codes (P0776, P0796, etc.)
  • TCC slip or converter shudder
  • Overheating in urban driving or high-mileage fleets
  • Harsh shifts or shift flares under light throttle

We build these transmissions to hold up — not just patch over factory flaws.
