6l80 swap
Good day,
I have a 6l80 swapped 2008 gmc sierra I used my 08 E38 OS 12617631 with a 07 T43 OS 24239353. On HP tuners I cannot see my transmission speed and output shaft speed on my ECM and HP Tuners is pinned at 255.
how ever I can see both readings if I select transmission and go to these readings. I also do not have cruise control, command start or TU/TD I’m not sure if they are related but I believe they might be at-least the first 2. Everything else seems to be working.
Does anyone know of anything I can do to resolve this or got a idea of a starting point?
I can post my Hp files if it would help
