The part was $80 it seems to have stopped the confused overdrive, but now I get a dead pedal goes to idle and comes back after about 5 second's. So the timbo you say, I will try it and hope they take it back it if it doesn't solve my issue, I am not wanting to pull the ECM. I think I should get a full diagnosis $200. Do you think this will prove out a new bad or wrong APPS or ECM? Thanks for the info When I took the truck to the transmission shop when I first had the confused overdrive symptoms they told me I needed a new trans.. So I don't trust anyone.

Peddle gose dead, goes to idle and comes back. My transmission would shift between over drive and top gear then I move a ground that is over the alternator and the issue gose away till I got Po121 low voltage , replaced APPS got 5v. But now po121pd

New APPS sensor installed now random Dead peddle 5.9 C. Could it be ecm , alternator, or ground issue.?
