On the 2017-2025 GMC Acadia, the second-generation Acadia (2017+) uses the GM 9T65 9-speed automatic transmission which shares known issues with the Chevrolet Traverse and Blazer. Common complaints include harsh 1-2 upshifts, hesitation between 5-15 mph, lurching on light throttle in stop-and-go traffic, and the transmission hunting between gears on hills. GM has released multiple TCM calibration updates. The transmission is extremely sensitive to fluid condition — extended intervals with aging Dexron HP fluid contribute significantly to shift quality degradation.

This issue also affects: Cadillac XT5, Cadillac XT6, Chevrolet Camaro

Common Symptoms

  • Harsh or jerky 1-2 upshift between 5-15 mph
  • Hesitation when pulling away from a stop
  • Transmission hunting between gears on slight grades
  • Vibration or shudder during light acceleration
  • Delayed engagement from Park to Drive
  • Slip or flare on 2-3 shift under load

How to Fix

TCM recalibration with latest software (multiple revisions released). Full transmission fluid exchange with Dexron HP (ACDelco/GM 19354121) every 45,000 miles. Valve body and solenoid pack replacement (OEM 24043134) if software updates fail. Allow 500+ miles for relearn after any TCM reset.

Typical repair cost:$0 - $3,500
