I have a 98 allegro bay with allison trans. On our last trip, stopped for gas and when we left, the auto park light would not go out. Holds good on a slope when shifter is in park so i know the trans is coming out of park. shifting out of park causes the light to go out for about a second then it comes back on. I think it is probably a sensor but which one. ANY HELP WOULD BE APPRECIATED.
I DID A LITTLE TROUBLSHOOTING ON MY OWN AND IT LOOKS LIKE A PRESSURE SWITCH AN THE CONTROL UNIT THAT ENGAGES THE AUTO PARK. PART # 15961566. IF THIS WORKS I'LL LET YOU KNOW.
