Volvo XC90 transmission not in parking position after TCM replacement on Volvo XC90

Some Volvo XC90 owners report experiencing issues with their transmission not being in the parking position following a Transmission Control Module (TCM) replacement. These problems can occur if the TCM is not properly programmed, as it plays a crucial role in controlling transmission shifts and ensuring correct gear positions. Additionally, owners may find that resetting the transmission fluid counter and performing a drive cycle are necessary for the vehicle to function correctly with the new TCM. Some owners also note that holding the accelerator pedal in a fixed position during acceleration is essential for the TCM to adapt for optimal shifting performance. Furthermore, issues with the transmission gear lever getting stuck in the park position may be linked to faulty components, such as the interlock shifter solenoid. It is advisable for owners to check the programming of the new TCM and ensure all components are functioning correctly to effectively address these issues.
