Chevrolet Silverado 3500 shift position indicator malfunction due to heat-related shift module issue on Chevrolet Silverado 3500

Some Chevrolet Silverado 3500 owners report experiencing shift position indicator malfunctions attributed to heat-related issues with the shift module. These malfunctions may stem from a failing control module that manages the gear shift indicator light under high temperatures. Owners are advised to seek professional diagnosis, particularly if they encounter the Check Engine Light, incorrect gear readings, or improper movement of the shift indicator. Common OBD-II codes associated with these problems include P0750, P0751, and P0752, which indicate various solenoid malfunctions. Additionally, it is recommended that owners avoid shifting the transmission out of neutral or pressing the gas pedal until the transfer case has fully shifted to prevent further complications. To resolve misalignment issues, adjusting the shift indicator to align with the "P" icon for Park is suggested. If the Gear Selected display does not correspond with the shifter position, diagnostic steps should be undertaken to determine the cause of the discrepancy.
