The service rep said it would take 1 hour to download (whatever that means). 1 hour to download the update? 1 hour to update? He didn't seem to computer savvy and most likely used the wrong terminology.

Anyway, they updated my TCM and shifting has been great so far without any issues like before with jerky shifts and delayed rev matches.

Lmao, the TCM file I downloaded off techstream with this TSB was so small probably only would take a minute to download unless they had really really really bad internet, I have it on google drive somewhere stille. They probably meant 1 hour to flash it to the car, theres a long process that involves putting the car on a charger and a pre-check diagnostic thing.
