John Deere 350C Reverser Problems

I am getting erratic behavior from the reverser system. It seems to be attempting to remain partially in forward all of the time so when you put it in reverse the two clutches are "fighting" each other. I have been told that when the clutches themselves fail, they just slip so the machine will not move.

Are there any O-rings or gaskets that are prone to failure that allow some pressure to be applied tom the forward clutch?

Is it perhaps the Forward-Reverse valve that is worn? I see no O-rings on this valve in the parts schematic, so I am wondering if this part is prone to failure?

Call me lazy, but is it possible to remove the reverser valve assembly without removing the radiator, then engine, then the entire reverser?
 
The reverser control valve CAN be removed without taking out anything else (like the engine or reverser housing). Taking it out though isn't likely to do you any good. Sounds like you've got burnt/warped clutches that are dragging. That is common in worn 350-series reversers.
 
Thank you for the replies.

A mechanic at Pape Machinery (local JD dealer) had the same diagnosis. Just got the engine out last night.

Should I remove the entire reverser housing or just the clutch pack / gear and shaft assembly?
