My transmission control module failed under warranty. The dealer admits that the TCM is under warranty and replaced it. However, while the dealer agrees that the transmission fluid needs to be replaced (because it’s burned), the dealer is taking the position that the failure of the TCM has nothing to do with the reason the ATF needs to be replaced. Car has had regular oil changes and no prior need for ATF replacement. There is no specific recommendation for the ATF replacement. Car is six years old and has approx. 40,000 miles.
I’ve looked on line and it looks to me generally like the TCM failure can affect the ATF (which makes sense because the TCM regulates the transmission, and the transmission is what burned up the ATF). But any specific thoughts or feedback would be helpful and much appreciated!
