[QUOTE="Carey Frennier, post: 983745, member: 66764"] The TCM is actually located with the valve body. This is why the valve body for the 6R transmissions seem to be so insanely expensive. It can be programmed remotely through the OBDII port. Unless you can bypass the TCM code, only a dealership can adjust your trans. However, there are a few tuners who can do this. Supercharged SVT's tuner can do it and Torrie from Unleashed Tuning can do it. As far as I've found...they are it. I've tried Lethal Performance, BBR, Brenspeed, and a slew of others with no results. The issue with the adaptive learning system is basically this: the Metronics re-calibration systems that learn and adapt to your driving style unfortunately pick up stray signals from other devices and frequencies through the vehicle. This cause odd up-shifts and down-shifts. The most common is the downshift bump/surge. I've done the "battery fix" on my 08 and it did work for awhile. Eventually, the issues that caused the flare did their job again and I had another downshift bump. My 2010 did experiance these issues right when I first got it but only for a couple days and it was good to go. [/QUOTE]
