2001-2002 PT Cruiser TCM/TCU Transmission Control Module 05034014AA OEM

symptoms of a bad TCM or transmission control module, and how to tell if it's failing. If your car is shifting erratically, dropping into neutral on the highway, or completely refusing to crank, your TCM is likely dying. The TCM acts as the brain of your automatic transmission, calculating exactly when to shift gears based on speed and throttle input. If you drive a 2011-2018 Ford Fiesta Ford Focus, you're more than likely way too familiar with these symptoms on your vehicle. It's rarely a mechanical transmission failure. 9 out of 10 times, it's the internal circuit board or module itself cracked from heat or vibration. Do not pay dealership prices, do not wait months on back orders.
