In a 2003 Chevy Silverado, the TCM, which stands for transmission control module, is typically situated on one side of the transmission. This small metal device comes with a plug-in feature and includes monitoring software to ensure smooth gear shifting. The TCM relies on information from various sources such as the driver's brake pedal position, wheel sensors, throttle position sensor, and transmission temperature sensor to control when gears shift. If the TCM malfunctions, the driver may experience issues like difficulty downshifting when slowing down or coming to a stop, delayed upshifting during acceleration, or the transmission shifting to neutral unexpectedly. Replacing the TCM in a Silverado can cost approximately $1,200 for parts and labor.
