6L80 transmission rebuild, relearn, & TCC wiring - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey guys
I rebuilt the 2011 6L80 and reinstalled it into my sons truck and was told to re learn the transmission through hp tuners. When I do it, it asked me to apply the brake. When I did I got nothing and the relearn aborts.
So I guess I have a TCC wiring issue.
I have wired it to 12v brake applied, ground when applied and even installed a 1k resister on the ground wire through a relay.
No matter what I did the message asked me to apply brake and then it would abort.
The truck does not move in drive or reverse.

Anyone had this problem? Can anyone help?
