P2714 on Buick by model: symptoms, diagnosis and fix
Separate from the well-known low-speed shudder, the VT40 continuously variable transmission suffers hard failures of the line-pressure control solenoid circuit. When the solenoid sticks off, the belt-and-pulley set loses clamping pressure, the transmission cannot transmit torque, and the vehicle abruptly stops accelerating - owners describe engine RPM climbing with no forward motion, or being unable to exceed 20 mph with the pedal floored, sometimes on a highway. Failures are reported between roughly 40,000 and 83,000 miles, and multiple NHTSA complaints describe a second failure after an earlier transmission replacement. Some units have been found with essentially no fluid in the sealed case at teardown.
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
Do not clear the code and keep driving; continued operation with low line pressure destroys the belt and pulleys. Retrieve P2714/P0700 and check line pressure and fluid condition. In GM practice this is almost always resolved by transmission replacement or a remanufactured unit rather than a solenoid-only repair, because by the time the code sets the variator surfaces are already damaged. Insist on documentation of the fluid fill and level check on the replacement unit, since dry-at-delivery units have been reported. Verify powertrain warranty coverage (5yr/60,000 mi) before authorizing repair.

First-generation Enclaves (2008-2017) use 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. Failure typically occurs in higher-mileage 2008-2012 builds.
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.

Frequently asked questions
What does P2714 mean on a Buick?
P2714 stands for "Pressure Control Solenoid D Performance/Stuck Off." This is a transmission code. Automatic transmissions use pressure control solenoids to precisely regulate hydraulic pressure to clutches and bands so shifts are smooth and firm. P2714 means the transmission control module commanded Pressure Control Solenoid 'D' but the solenoid didn't perform as expected — it appears stuck in the 'off' position or isn't building the pressure it should. This commonly causes slipping, harsh or delayed shifts, or the transmission dropping into a protective limp mode. On Buick it is documented across 2 models: Encore GX, Enclave.
What are the most common causes of P2714?
The most common causes of P2714 are: Failed or stuck Pressure Control Solenoid D, Low, dirty, or contaminated transmission fluid, Internal valve body wear or debris blocking the solenoid, Damaged wiring or corroded connector to the solenoid, Clogged solenoid filter screen or fluid passage, Worn internal clutches affecting pressure response, Faulty transmission control module (less common). The specific cause varies by vehicle.
How much does it cost to fix P2714 on a Buick?
Published repair estimates on Buick range from $2,500 to $7,800 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
