I have a 07 Silverado with a 4l80 swap. The stock harness was repinned for the swap. Built 6.0 with TTs and I want shifts at 6800rpm. Everything else is working great except the WOT shift points. Tranny Specs are as follows:
Jake's stage 3 4l80 with trans brake valve body
FTI 3500
3.42 rear gear
30" tire
I've set the shift points to hit at 6800 but no matter how high I set the shift points it still hits at 6000 rpm. Anybody run into this issue? I've seen guys have issues with the trans not shifting and banging the rev limiter but not an issue where the trans shifts out too early.
