Transmission Control Module
for 1969 Mercury Marquis 351ci V8 · RWD
🔧Does this apply to your car? Most transmission control modules must be programmed and have adaptations relearned after replacement — and on some vehicles (many Mercedes 722.9, ZF mechatronic units) the TCM lives INSIDE the transmission, which changes this from a 1-hour job to a 4-8 hour job. Verify your TCM location before quoting.
