Hey Mike,
That is one heck of a good idea with regards to the transmission. So what you are saying is: since the egine is not moving the drive shaft, it will not move the gears and will not help to "pop" it out of gear - right?
I will not be able to move the truck around, but with the clutch in, I could raise the rear tires and try to move a tire a bit to possibly get it out of gear? I guess I would have to raise both rear tires or esle I won't get it to move...
As you can probably tell...I am a "one man show" out here...I will see what I can do!
Please let me know if I understood you correctly.

Some valves move a tiny bit when I hit the springs with the rubber mallot..I think they will all be loose soon.
