Truck was driving fine. Pulled the rear actuator to inspect and when I re installed, the truck would not go move in any gear. Its an automatic and when you shift into drive, nothing, reverse nothing. When you put it in park, you hear a whirring sound that winds down almost like its being put in park while it's moving. Does the transmissions computer need to be reset or something? Im sure the actuator is put back in correctly...Thank you for any help!
