Pull up on any Escalade V’s ? Bet that will be fun.HP Tuners has a form on their website. Basically you select your trans and enter your VIN and I assume they send a new unlocked TCM unit. In my case HP Tuners reached out gave instructions for sending my unit to them. They worked whatever unlock magic that they do and sent it back. Turn-around time for me was about two weeks. The cost was $400. I'm not sure of the exact reason my TCM had to be shipped but there were several atypical issues that needed to be dealt with along the way so I just lumped it in with the rest of the unfortunate incidents. I was on travel for work when the tune/TCM tune took place so I can't really speak to what took place during the actual dyno session. Also the reason I don't have any new dyno video. I will say the thing drives a LOT better now. Overall driving manners are way closer to stock than it was before the trans tune.
