Hey in2pro. After tryiing what you had sent me about the shift solenoid and it checked out ok, I finally figured out what was wrong. It is kind of one of those "how dumb can I be" times. I had replaced the ignition lock cylinder, casing and switch. When I put the new switch in, the gear was not meshed with the lock cylinder so that the switch did not turn enough so the shifter would work. I got to thinking about it yesterday and took the switch out, bumped the gear up a couple of notches to the last one and what do you know, it works!

I still do have a lingering problem that actually led to all of the trouble in the first place. Periodically, the battery warning light comes on when I turn the engine off and remove the key. I had noticed I could shut it off before by reinserting the key and twisting it back. I got to thinking the cylinder lock and switch were probably wearing out. I couldn't get the damn cylinder lock out of the casing so I replaced the casing also. But that did not solve the problem. the battery light turns off when the engine is running but still comes on when the key is off. I think now it probably is a short somewhere so I am going to try to chase it down. If I don't watch it close, it will run the battery down overnight. Any thoughts.

 

Did you ever figure it out ? I am having the same problem I changed the lock cylinder and case the switch was off I got it and then one day I turned my truck around backed it up and next morning would go out of park . I've replaced the switch . The brake light switch. Shift interlock solenoid and still stuck in park
