Folks with Auto Trannys need to reset them ocassionally. The reason is the torque converter goes into lockup based on throttle position and when the calibration gets off it will drive you crazy unlocking the TC when it should be locked up. i. e. Under light throttle an out of cal APPS *thinks* it's at the idle position so it tells the TC to unlock. It will absolutely drive you crazy and until you know better you'd swear something was going south in the trans.
 
1. Disconnect your batteries then let it sit. I let my truck sit a couple of hours to overnight but I think the minimum might only be 30 min.



2. Reconnect the batteries turn the ignition to "on" (DO NOT CRANK IT OVER).



3. Slowly push the go-pedal to the floor and slowly release it back up (repeat a few times).



That should re-calibrate your pedal. You can also take the cover off the APPS unit and put some dielectric grease on the connectors in there as they dry out.
