Transmission controler

Had mine fail and replaced. Where is it located as I want to know if it is in the transmission and they had to change the ATF. It was under warranted so did not see an invoice detailing costs.

I have just over 50,000 miles on it. Mostly gently driven and think 50,000 is too early to have to change the fluid.

yup inside the trans , and its better to change it often , then to wait to long

The pan had to come off to pull the TCM, hence the fluid change.

Thanks for the info, I can wait another 50k to change the fluid

id recommend 20-30k on the fluid filter changes

I think it's a bit weird you didn't get an invoice detailing the work performed. I did when I had a TSB performed for the 2-3 shift flare under warranty. It holds the dealer accountable for work performed in case anything comes into question in the future.
