Noptul Transmission Control Module, Suitable for Mazda 3 2.0L 2010 2011, Automotive Replacement Part TCM TCU LF8M189E1F

Installed and is not working. I ordered another one thinking I had bad luck with this one and again it did not work. I went to a transmission place. They ordered the same exact part from the dealer and it worked. Why would you sell defective parts?

Module drew more fault codes than the old one. Refund approved by amazon last month.Returned item on the 25th of September . Item arrived on the 29th of September at return location.Since than I received no message nor a refund back on to my credit card.I guess they keep the item plus the 400 $ US for themself. Therefore I highly recommend NOT to buy anything from this supplier.

This product is not compatible for 2010 mazda 3... the check engine light comes on

Your car will run but you will still have an error code p06b8 and it might cause CEL to come on. It's not compatible with the Mazda ECU.
