Step-by-step checklist for transmission control module replacement. Document everything, verify everything, miss nothing.
A TCM swap is one of the most documentation-heavy jobs in a shop. The difference between a comeback and a clean install is what you record before you pull the old module.
This wizard walks you through the full procedure: pre-pull scan, documentation, physical install, and post-install verification. Each step has a checklist — complete every item before moving on.
Never skip the pre-pull scan. If the vehicle comes back with a new issue, you need proof of what was there before you touched it. CYA is not optional.
