AS68RC code P0756 FIXED

Post by Rudy210 » Tue Apr 18, 2017 12:21 pm

I swapped press sw 4 and 8. Code returned. I went through the diag flow for P0756. I believe it will need a TCM. Has anyone ever replaced a TCM because of a code like this?
Or any other type of code similar to this?
Thanks

Well we finally fixed this thing. Installed linear solenoid B.. Allison trim solenoid. Although we did not have a direct code for it. And double checked all press. sw. connections. Trans codes gone. Was then able to relearn. Trans works great. Hope this will help someone.
