Re: 6L80 transmission rebuild, relearn, & TCC wiring

Well its been months since i have worked on this.
When I started this truck I didn't have HP tuners yet and had a few others work on it. Well I realized that the others did what they could but created problems with Torque management, Air flow, MAF Etc.
So i just put the truck back to 100% stock, PCM and TCM. Wow what a difference in how the truck drives.
Of course the shift points and firmness of the shifts are not right but I am going to start slow and take 1 step at a time.
Starting with the tune I received from Mike at Century Transmission to take advantage of the new parts in the trans I received from him.
Then I will work on the TU/TD.
Then correct the shift points and shift firmness.

Anything else you can think of???
