Ford 3600 won't shift into 4th/8th gear

I"ve got a Ford 3600 with an 8 speed transmission. It will not shift into 4th/8th. I had the cover off a few days ago, and checked the detent (ball looked fine) - wouldn"t shift with detent ball/spring/plunger removed. The set screw is set well in its divot on the rail. With the engine running and clutch out I tried shifting and could hear a low-level growl.

I"ve concluded that there must be a misalignment at the shift collar. Maybe a bent fork.

What sayeth you Gurus??
 
will it shift with the engine off?

when you shift it to 4th, then pull the cover.. does it look engaged?
 
Howdy Chris,
It will not shift into gear with engine on or off. I tried it with the engine on and clutch out to see if I could hear it grind - and it did grind.
 
My money would be on a bent fork... provided the shift lever is actually engaged in that rail.
Can you move the left rail rearward with a pry bar with the cover removed?

The fork is definitely engaged on the rail. Cannot move the left rail rearward with a prybar (BIG screwdriver - didn"t get rough with it).
