Used Transmission Control Modules for Sale
A transmission control module is far cheaper than the transmission it controls, and shift faults are often the module rather than the gearbox — which is worth establishing before replacing either.

- Harsh or delayed shifts that a fluid service did not fix
- The transmission dropping into limp mode
- Refusing to shift out of a single gear
- Transmission fault codes with no mechanical symptoms
These are the things customers describe, not a diagnosis. Several of them have more than one cause, and some are cheaper to fix than replacing the part. Tell a specialist what your vehicle is doing and they will tell you honestly whether this is the part you need — including when it is not.

Common questions
Will a used TCM fit my car?
We match it to your VIN before it ships. Give us the VIN and a specialist confirms the exact vehicle the unit came off and whether it fits yours — before you are charged, not after delivery.
What warranty comes with a used TCM?
Warranty up to 1 year. The exact term depends on the part and is shown on its listing, so you know it before you buy rather than after. Your order number is your warranty number — there is no separate certificate to keep.
How long does a used TCM take to arrive?
Most parts ship to all 50 states in 3–5 business days. If yours needs longer, we tell you before dispatch. Delivery is charged separately, and you see the exact charge before you pay: on the product page and at checkout for listed parts, or in your quote for parts we source. Canada delivery is confirmed at quote.
Are these new or used?
OEM used parts only — never aftermarket, never a third-party copy. Every unit came off a real vehicle and is tested before it leaves us.
