Hey all Before I get flamed I did search and read but didn't seem to find my exact issue. However, this is a 2004 siverado 4.8/4l60e swapped to a 6.0/4l80e. Trans is a fresh build and works perfectly with 3200 stall. This truck has a cam. 230/236 cam ish. The truck dyno'd at 370 hp. Getting on to it, the truck will not lock up the TCC by itself but it will lock up commanding it. The brown wire on the harness was moved to the appropriate location for the TCC and the pigtail for the front speed sensor was verified to be pinned to 22 and 23.
The things that i have noticed. There aren't any DTC's present but The input speed sensor is going bonkers. I replaced it and it is still going nuts. 8192 then way down and back up etc. I looked at the tune, the tune was by someone else but it appears to be ok. ... for the things i was looking for anyway.
I will attach the tune and a log file. Maybe one of you can give me a place to look or something to try. I would appreciate it very much.
I can upload more logs if you like but they are all the same.
4L80E no TCC lockup command
