Hey everyone,

I have a R3644 that will not stay in forward gear. Soon as throttle is applied, it pops out. Reverse works fine. If I physically hold it in forward, it does work but I fear the problem is just going to keep getting worse. Tractor has 220 hours on it.
I had the shifter pop out of gear on me a few times in the past but never to the point of always popping out, as it does now.

Any hints to what the problem may be would be greatly appreciated.

Thx.

Hoping you figured this out by now and got it fixed?
Was it the clutch?
Or perhaps the shifting fork that was worn down from shifting from fwd to reverse without the tractor being fully stopped?

Bones1, that's what mine occasionally does.... it pops out of reverse.
The nut that "backed off", which one, where?
How do you know the shifter fork is broken? Did you see it? Isn't that located inside the transmission housing in the depths of the tractor?
