How to diagnose and fix P2714: most-reported vehicles
Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Land Rover Range Rover Sport · 2014–2022
The ZF 8HP70 eight-speed automatic transmission used in the L494 Range Rover Sport develops valve body and mechatronic unit faults. Symptoms include harsh shifts, delayed engagement, and occasional limp mode. The solenoids in the valve body wear and cause improper fluid routing. The transmission adapts by increasing line pressure, which accelerates wear on the clutch packs.
Common Symptoms
- Harsh or jerky shifts especially 2-3 and 5-6
- Delayed engagement from Park to Drive
- Transmission fault warning
- Limp mode (stuck in one gear)
- Shudder during light acceleration
How to Fix
Replace or rebuild the valve body and mechatronic unit. Perform a transmission fluid and filter change using only ZF-approved fluid (ZF Lifeguard 8). Reset the transmission adaptation values after repair. Some specialists offer a rebuilt valve body with upgraded solenoids.
Owner tips & cautions
- TipChange ZF 8HP fluid every 60,000 miles despite the "lifetime fill" claim. Use ZF Lifeguard Fluid 8 and a genuine ZF filter kit. This dramatically extends valve body life.
Cadillac STS · 2005–2011
The GM 6L50 6-speed automatic transmission in V6-equipped STS models is prone to overheating and developing harsh shift quality. The transmission fluid cooler is undersized for the vehicle weight, and the valve body solenoids degrade from heat cycling. Fluid darkens rapidly, and shift quality deteriorates with delayed or slipping 3-4 and 5-6 upshifts. The torque converter clutch also fails prematurely from heat damage.
Common Symptoms
- Harsh or delayed 3-4 upshift
- Transmission fluid dark or burnt smell by 50,000 miles
- Transmission temperature warning
- Torque converter shudder at 40-50 mph light throttle
- Slipping in higher gears under load
How to Fix
Perform a complete transmission fluid and filter change (not a flush) every 30,000 miles using Dexron VI. Install an auxiliary transmission cooler for vehicles used in hot climates or towing. If shifts are already harsh, a valve body rebuild or replacement with updated solenoids may be required. Torque converter replacement is needed if shudder is present.

Chevrolet Express · 2010–2020
When the Express moved to the 6L80 and 6L90 six-speed for the 2010 and later vans, it inherited that family's torque converter clutch problem. The TCC lining delaminates, and the shed material scores the fluid pump - so what starts as a light shudder felt at steady cruise, often described as a chuggle or 'fish bite' between roughly 35 and 60 mph, progresses into a pump and converter failure that takes the whole transmission with it. GM's own path on the complaint is graduated: TCM reprogramming for the chuggle concern, then a fluid exchange to the specified low-viscosity synthetic ATF, and finally converter replacement when the clutch is too far gone. That progression is exactly why the shudder must not be ignored - the flush only works if the wear is caught early. Documented as a 2010 and newer issue only; do not attribute it to the 4L60E/4L80E vans.
Common Symptoms
- Shudder or vibration at steady cruise between about 35 and 60 mph
- Chuggle or bucking sensation under light throttle
- Sensation like driving over rumble strips that comes and goes
- Friction material in the transmission pan
- Eventual harsh shifting and slipping as the pump scores
How to Fix
Address a shudder at first onset. Start with the current TCM calibration, then a full fluid exchange to the specified synthetic low-viscosity ATF (this is the GM-directed remedy and genuinely resolves early cases). If the shudder persists, or if the pan and cooler show friction material, the repair is a new torque converter together with the pump cover and cover housing, plus a complete flush of cooler and lines - reusing a scored pump guarantees a repeat failure. Servicing the fluid on a real interval, rather than treating it as fill-for-life, is the single best prevention on a commercial van.

Frequently asked questions
What does P2714 mean?
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.
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?
Repair costs for P2714 range from $250 to $7,800, depending on the vehicle and root cause.
Which vehicles are affected by P2714?
Au7o has documented P2714 across 8 vehicle models from 5 manufacturers: Buick, Cadillac, Chevrolet, Land Rover, Toyota.
