Pressure Control Solenoid 'D' Performance or Stuck Off

…I have taken the car to both a Chevy dealership and an independent shop, who have both confirmed that there is a "loss of forward gear" and pulled codes P2714 and P0700. I have been told that I most likely need a transmission replacement at only 34,000 miles.

- started shutting shutting off at while in drive. - started having reduced power - started idiling high while driving - initially there was no codes - last night I drove, I put in drive gear but it was delayed so I had to keep moving from park to drive for it to full go into drive - the codes came P0325 P0505 P0507 P0700 P1101 P2714 After I was driving up an incline the car stopped moving forward and started reversing backwards. One other independent shop advised they were able to produce but couldn’t figure out the problem because no code were shown at the time. There has been many people having the same issues I started off with and I found the forum to file a report .

…These problems were documented at AutoNation Chevrolet South Clearwater, where multiple diagnostic trouble codes (P0700, P0717, P2714, P2716, P0706, and U-codes) were recorded but not properly investigated. No test drive was performed despite being claimed by the service technician, and the applicable TSB was not referenced. By July 2025, the condition worsened into a complete transmission failure, with additional codes (P0700, P077C, P17F6, P17FB, P1872). The dealer’s estimate required a full transmission replacement at nearly $10,000. GM reviewed the case through its internal Policy Evaluation Tool and increased goodwill assistance from 15% to 40%, while AutoNation contributed only $500…

I purchased this vehicle Oct 2024 from CARMAX Tallahassee FL. When I test drove the vehicle I noticed a pause when it was placed in drive. The after about 10 seconds it would engage and begion moving (49,000 miles). I told the dealer and the said it my be the torque and advised me to take it to the GM dealership. I did take it 4 times. The said they adjusted the transmission software , but the problem persisted. Now the manuafactures warranty has expired and the vehicle is much worse now. It atcually throws a check engine light. I went to auto zone for the plug in tester to fine out what the code was. P0700, P0746, P2714. The truck will completely lock and not move. This vehickle has not…

COMPONENT: Transmission control system / GM VT40 continuously variable transmission (CVT), RPO code MRG - a rare, fleet-only configuration for this model year, confirmed via the vehicle's factory build/RPO code list. WHAT HAPPENED: While stopped at a red light (engine idling just after an automatic stop-start restart, foot on brake only, no accelerator input), the check engine light came on along with an unusual mild jolt sensation from the drivetrain. Diagnostic codes P0700 (Transmission Control System - MIL Request) and P2714 (Pressure Control Solenoid D Performance/Stuck Off) were stored. Drove approximately 4 miles without further incident; vehicle has since been limited to short…

My 2021 Chevrolet express van with an 8L90 transmission has failed after only 80k miles, willing to have it inspected. Check engine codes show P0700 and P2714 on 02/08/25. No prior warning lamps. This product has put my safety at risk due to overheating and making the vehicle go into limp mode while on public roadways. The product is known to fail for trucks alike with the same transmission but has yet to be reported for the Chevrolet express. Has only been confirmed via OBDii scanner from parts shop.

…The codes that my car had thrown were the codes that appear in Special Coverage [XXX] (P0871, P2714, and P0871-00). These were the same codes that were thrown at the time of the original replacement in 2016. Upon doing a full diagnostic of my vehicle, the dealership had agreed with the prior codes listed. However, GM is denying my claim of this coverage due to my reconstructed title. After looking at GM's own website where I had to enter my VIN, the coverage for this adjustment says it is active, and will not expire until my car reaches 120,000 miles, or until January 25, 2025 (10 years after it was placed in service). My car is currently at 113,760 Miles. It does not say anywhere that a…

…This generates a P2714 code. I had the car looked at by a GM dealer as well as an independent transmission repair shop and both indicate it will likely need a new transmission. GM is fully aware of the defect and has issued a service bulletin, TSB-24-NA-009 to instruct dealers how to diagnose and repair the problem. The bulletin proves a widespread engineering or manufacturing flaw exists. However, GM is treating this as a maintenance issue rather than the severe safety hazard that it is. It is my understanding, GM has since abandoned this transmission on the newer models, further indicating that GM knew these transmissions were not designed well. I am requesting the NHTSA office…

…This issue occurs from probably 60,000 - 90,000 miles when the system finally threw P0700 and P2714 codes to point to the issue.

The affected components are the electrical system, engine, and power train. In March 2025, my 2021 Chevrolet Tahoe displayed multiple warning lamps across the dash, including traction control and check engine lights. The vehicle shifted erratically and sometimes entered limp mode. I brought the vehicle to AutoNation Chevrolet South Clearwater for inspection. The dealer replaced the battery, dismissed my concerns, and stated that a test drive was performed, but the mileage in and out on the invoice was identical, showing it never actually occurred. Diagnostic trouble codes (P0700, P0717, P2714, P2716, P0706, and multiple U-codes) were present but were not fully investigated. A GM Technical…
