2012 Chevrolet Silverado 1500 transmission problems

Filed Jul 14, 2025 · Electrical, Transmission · FL

I got the code p2138 and I’ve had it inspected and throttle body and accelerator pedal assembly replaced. The problem is still not fixed. I lost power driving to work and heavy vibration and shaking. If I pull out in a turn and someone is coming up fast and this happens again it reduces my engine power and could cause a crash. Problem has been confirmed by a licensed mechanic, AutoZone, oreillys, and an independent mechanic. There was absolutely no warning this was gonna happen. It happened and I’ve spent $3,000 on replacement and labor costs trying to figure this out.

My truck has been having issue after issue with sensors going bad and check enginge light always coming on. Now I have a transmission issue with a solenoid going bad. The transmission has had the "clunk" as people discribe it since I purchased it. Nothing was wrong with it so I was told and that was normal. There are so many complaints on this year and make silverado its pretty sad that nothing has been done. Now my truck sits and still paying the note because of this transmission issue that a ton of people have reported. How many thigs do I have to change before the check engine light stops coming on. Please help all of us who own a chevy and have gm make this right.

I fought gm on this for 7 months. And did so 30 days from my purchase date. When I slow down my truck makes a horrible clunking noise. And will rev up in a sense and push you forward. Most of the time it's only probably a food but other times I has caused me to go through stop signs. Luckily no one is there but I fear that when I have my fiance and 3 kids in the truck I may get pushed forward and t boned. Or I may go into someone in front of me. Or into a fence. And they say it's normal every time. But it's getting worse and my thing is is if it's normal.. Then it's a serious issue. I have read reviews about other people having the same issue. This should be recalled. It's not safe and definitely not practical. They say it has something to do with my 6 speed. But I fought gm and he place I bought it from for months and months. Starting from repairs on my truck that was promised to be fixed to this transmission issue and them claiming they fixed it with some sensor. Then lying saying they never fixed anything when gm questioned them. Luckily I had someone that worked there that felt bad for me so he gave me all the info I needed. All in all gm ended up giving me a bumper to bumper gm warranty for 4yrs. For a problem they claim was normal. That's generous of them. But it's getting worse and I'm scared for my families safety.

At 170208 miles the cam went out while driving it on a city street it started tapping lifters, I took it directly to repair shop for inspection and a new motor has to be put in. I bought this vehicle one year ago at 139171 miles with powertrain assurance with apg corp. But no one wants to cover it now that it has issues. Even with regular maintenance.
