2012 -2013 Mazda 3 2.5L Transmission Control Module (TCM) Exchange

Warning! Be aware!

Lately we have been receiving many Mazda TCM cores from customers who have purchased TCMs from Chinese resellers on ebay. These TCMs are being advertised as “new” “refurbished” and “remanufactured” when they are none of these things. They are old cores from Mazda’s past recall, that these sellers purchased and are reselling back with the part number stickers removed and then spray painted silver; absolutely no repairs have been done to these modules! These are faulty modules that will either not work immediately (because they sent the wrong year with the part # removed), or will not work eventually when your vehicle heats up. They will promise to replace it but will stall until the Ebay return period is up.

To avoid wasting your time and money, do not buy these TCMs! We may also not accept them as cores for exchanges. 

ATTENTION!!!

This is an EXCHANGE LISTING - We will send you a remanufactured 2012- 2013 Mazda 3 2.5L TRANSMISSION CONTROL MODULE from our stock, then you will return your bad CONTROL MODULE back to us.
