Can you test a transmission control module?
But on some vehicles, the information is often found in a separate Transmission Control Module (TCM) or Body Control Module (BCM). A scan tool can also help you check for communication faults between the PCM and transmission controller if the vehicle has separate computers.
Can a bad TCM cause a car not to start?
If the sensor that tells the PCM if the transmission is in gear or park or neutral (prndl) is incorporated in the TCM it could prevent starting the engine if the PCM thinks the transmission is in gear.

Where is a transmission control solenoid located?
A transmission control solenoid is located in the valve body in the ‘transmission control unit (TCU) of a system. It can be seen after removing the transmission pan attached to the valve body. Generally, multiple solenoids are used in a system, and each has color-coded wires for ease of identification and replacement.
What does a bad TCC solenoid do?
When the solenoid is open, the engine is locked to the transmission so there is no transmission slip. With the transmission unable to slip, the engine will stall when the vehicle comes to a stop. This type of solenoid failure will set a Diagnostic Trouble Code causing the Check Engine Light to illuminate.
