Have Transmission Questions? Ask a Mechanic for Answers ASAP
Has the vehicle been scanned for misfire codes? A misfire in the engine could cause the condition that you are describing.
Yes. The tech also had the code reader plugged into the car the entire time we were driving.
Sound like it is likely an internal transmission problem. It very likely could have been caused by disrupting the transmission fluid. How many miles are on this vehicle?
What did the transmission shop say when you took it back? were they able to get it figured out? please let me know if you need more help!
The car jerked a couple of times on the way to the shop. The tech drove the car, then I drove the car with the tech and the car never had the issue. He had the code readed plugged into the car and of course did not get any issues.
Maybe some dirt or debris was dislodged when performing the transmission service. This could have caused a shift valve to stick which is maybe what you felt while driving the car initially. Is the problem resolved now?
I have put in injector cleaner into the gas tank. Seems to be better, not had the issue recently.
