P2714 on Buick by model: symptoms, diagnosis and fix
The VT40 CVT can lose forward gear, slip or lose propulsion with the check-engine light on. GM lists a pressure regulator or clutch regulator valve sticking in the valve body, forward clutch piston damage, or wear in the primary pulley bearing bore as causes; running in this state can damage the drive chain and pulleys. Applies to: 2020-2024 Buick Encore GX with the VT40 CVT (bulletin 21-NA-003) and 2020-2025 (bulletin 24-NA-009): front-wheel-drive models with the 1.2L LIH or 1.3L L3T. Not the AWD 9-speed automatic.
Common Symptoms
- Vehicle will not accelerate past ~20 mph with pedal fully depressed
- Engine revs but vehicle does not move
- Delayed engagement when shifting into Drive or Reverse
- Loud whine or mechanical noise from the transaxle
- Sudden jerk followed by loss of drive at highway speed
- Speedometer rising and falling erratically
How to Fix
Under these bulletins, a technician first inspects the drive chain and pulleys with a borescope (bulletin 20-NA-120); if they are damaged the transmission is replaced. Otherwise the valve body, pressure sensors or solenoid body are replaced according to the codes and pulley pressures, and with loss of drive, slipping or burnt fluid the transmission is disassembled to repair the forward clutch or replaced if the primary pulley bearing bore is worn. Normal warranty rules apply; this is not a recall or a promise of free repair.

The first-generation Enclave (built 2008-2017) uses the 6T70/6T75 6-speed automatic, whose stamped-steel 35R wave plate can crack at the teeth after enough shift cycles. When it fractures, the transmission abruptly loses 3rd, 5th, and reverse gears, and debris can damage the valve body, drums, and torque converter. GM's bulletin and special coverage for this failure cover 2008-2009 Enclaves.
Common Symptoms
- Sudden loss of 3rd, 5th and reverse gears
- Slipping or no movement
- Harsh or no shifts
- Check engine / transmission warning light
How to Fix
Disassemble and rebuild the transmission with an updated/stronger wave plate, plus replace damaged hard parts and clean out debris; in severe cases a remanufactured unit is installed.
