The transfer case control module of the 2008 Chevy Silverado is located to the left of the steering wheel behind the driver's dash on the steering column. The TCCM is responsible for executing a request to change the drivetrain from "normal" to 4WD or 4-high or 4-low. The shift knob is also installed on the left-hand side of the driver's dash and signals the TCCM through a switch to enable the drivetrain shift. A warning light will illumine if the module detects a communication failure between itseLFAnd the PCM. Common symptoms of module failure include an instrument panel warning; inability to shift to 4WD and engine hesitation. The average cost to replace this component is between $530-$620 in parts and labor.

Does the TCCM have to be reprogrammed if you replace it with another one?
