Transmission Solenoid problems of the 2011 Chevrolet Impala

After about 30000 miles the transmission solenoid(s) are going bad intermittently. It's going to be a costly repair for a part that costs around 25 dollars or so. This seems to have been a continuing problem on the 4t65e transmissions. When you are at a complete stop with the vehicle in drive and go to accelerate you get no response except for higher rpm's and then the transmission suddenly engages and you get a violent surge forward with a loud bang. Gm knows about the problem and should initiate a recall to install new and improved solenoids.

The transmission will frequently fail to engage when starting from a full or partial stop. Turning left across traffic is extremely dangerous, as you never know when the transmission will fail to engage. This has been a ongoing problem with this vehicle since the car had 38000 miles on it. This is our third Impala that has had this problem. The first Impala that had this problem, the Chevrolet dealer could not diagnose. The transmission pressure solenoid was replaced by a local transmission shop. This fixed the problem for that car. We also have a 2008 Impala that has the same problem. Three Impalas, the same transmission problem in all three. The part needs to be recalled. We have delayed having the part repaired because it is quite costly and we had hoped that Chevrolet would do the right thing and recall the part on their own.

When your at a complete stop vehicle gives a hard jerk like someone has rear ended you. All of the Impala's have a failed transmission pressure control solenoid which can cause accidents when it jerks very hard causing someone to run into the back of another vehicle. No check engine light or anything will come on letting you know the problem. Years 2000 to 2015 all have the same problem. Needs to be recalled before someone seriously gets injured.
