Why would you reset your transmission?
Carrying out reset and relearn is important to prevent transmissions failure after fluid change.
What is a TCM fuse?
The TCM is an electronic mechanism that collects data from the transmission, interprets signals sent from other parts of the vehicle (i.e. throttle position sensor, turbine speed sensor, fluid temperature sensor, etc.), and helps to regulate the gears shifting.
What causes lost communication with TCM?
Dead battery. Faulty TCM. Problems with the TCM circuit. Problems with the data bus.
What causes a transmission control module to fail?
Usually, what causes a transmission control module to fail is voltage overload. When this happens, other transmission components of the vehicle start malfunctioning.

What happens when transmission control module goes out?
Bad Transmission Control Module Symptoms
Slow Acceleration: It takes longer than normal for your vehicle to pick up speed. Gear Slippage: Your transmission switches gears without warning or without you shifting. Inability to Shift: You can’t shift out of neutral.
What does resetting the transmission do?
Resetting a transmission is resetting the transmission’s control unit such that the stored shift pressure and timing values that have been learned over time are reset to default values. This is done using a bidirectional diagnostic scan tool that is capable of resetting the transmission.

Is PCM and ECM the same?
The main difference between the two is that the ECM controls specific parts of the engine, regulating and sending commands. While the PCM is used in newer models to control almost all engine functions.
What is the code for a bad PCM?
The PCM should give you a code for P0600 through P0606 indicating that the computer has a processor error. However, if the PCM is corrupt, then just like a desktop computer, there is no accessing anything and no codes are put out for the computer would have no way of sending a signal.
