If you are looking to manually reset your TCM (Transmission Control Module), the process is fairly straightforward. First, disconnect the battery cables from both the negative and positive terminals. Once disconnected, wait at least 10 minutes before reconnecting them. This will ensure that any stored energy in the system has been dissipated. After reconnecting the battery cables, start up your vehicle and let it run for a few minutes so that all of its electronics can be fully rebooted. Finally, shift through each gear while stationary until you reach Park or Neutral – this should complete your manual reset process! Remember to always follow safety precautions when working on car components - make sure no other part of your vehicle is running during these steps and wear protective clothing as necessary.
