Need help p0777

I also have an issue with my truck, I have a 2008 duramax with EFI live done by Idaho rob and I just built the transmission with a stage 5 ppe kit and before I took it in to rebuild it I had codes P0843, 848, 877, 735, 762. Tool it in cause blew the tranny and when thy installed the kit I am getting a P0762 now BUT ONLY when the tranny temp gets to around 167 degrees will it go to limp mode and give that code. I can also sit in one spot and not move while the truck is in drive with my foot on the brake and a few seconds BANG and the light comes on with P0762 code. All the valves were replaced along with the harness in the vb so we have eliminated that but I am stumped hard on this one especially when it only happens when the temp is around it's normal temp!
