1 Answer

remove shift relay block under hood, look for corroded wires to UNDERSIDE of relay sockets. common issue, under reported. in mean time, take cover off two relays, use your finger to close relay contacts, shift should work fine. what happens is open condition closes when downward pressure from volt/ohm meter is used to check continuity......then reopens when pressure is removed, drives you batty.
