My 2012 Ford SE stalls out between First, second and third gear whenever I am accelerating to 40mph. The Transmission error continues to pop up after driving for a long period of time. Whenever driving 50 mph to 70 mph as soon as I release the gas pedal, the car goes into neutral stall out & whenever I press down on the gas pedal nothing happens and I have to pull over & Turn the car off and turn it back on to reset the transmission computer. If I don't do that and I press the gas pedal again, the car would jerk and I have to pull over immediately and the car off. I cannot press full on the gas pedal because the car would not accelerate at full speed. Whenever I put gas in the car, it won't start right away. It would jerk and choke just to start up. It takes me a couple attempts to start the car after putting gas in order for it to start and go. …

Transmission has spontaneously went from overheating to not while driving, gears are slipping have speed and when it goes to shift all power lost, then it kicks back in. It was coded with transmission control module failure. The module and both actuators have been replaced now car will not relearn shifting patterns. Spontaneous overheating transmission messages just when car is turned on. Transmission control module has been programmed by dealership but all problems continue to exsist.
On highway with my 18 month old and as a cat merged on ramp I signaled and moved to left lane. I had to move and quickly so that another fast car would not hit me in the rear end where my baby was seated in car seat. In only the 3 seconds I had to make decision which hit would be better for me and my child, my car stuck in the lower gears and I could not speed up to move out of way or pass vehicle parallel my car was losing speed rather than gaining when I pushed in gas to floor
The transmission module, and Transmission. While on freeway with my family car shut off while driving. Yes , Yes , No there were no warning signs until after the jerking and shaking started after 39 days then the engine light came on. After that a that the sign said transmission over heating pull over and let car cool down. what was most scary is that it shut off while driving.

the car runs without power when shifted to drive gear. It is sluggish trying to speed up. Took to Ford Dealers on a recall with that is suppose to take care of it..nothing seems to have changed. I am not sure anything was done. trans makes a rough sound starting..
The TCU/TCM has been going in and out of control. Sometimes it will work then others it will shut off. Speedometer won't work, power steering won't work, cruise control won't work, etc. and when you do the transmission reset for it, it won't work at all.
Only 67867 miles and the transmision is not working . I only drive short distances. Allwise have a problem. Since I buy the car. I never complain because I am very busy. But. know the car stop complete
