LobsterThief Posted March 1, 2012 Posted March 1, 2012 Ended up swapping the tranny out. Please delete, thanks
Blue88Comanche Posted March 1, 2012 Posted March 1, 2012 sounds like what dad's libby is doing. from what i read the TCU may need to be flashed or replaced.
cruiser54 Posted March 1, 2012 Posted March 1, 2012 Year? TCU controls shifting, not the ECU regardless.
Geonovast Posted March 1, 2012 Posted March 1, 2012 Unplug the TCU, and see if it will shift normally with the selector.
