TN65 4 X 4, 4 wheel drive jumps out of gear

[nuttrees]

I own and operate a TN65 2003 model good tractor but lately as I live in Kentucky in the Appalachians mountains at 2000 feet in elevation and own and operate a 40-acre orchard well as you might imagine from the ridge line to valley can be 2 to 3 hundred feet well any way can you imagine sliding down the Mountain side when the 4-wheel drive pops out of gear

Now My Question is to anyone what is going on it works then it pops out on a strain I have slide Tight cheeked for my last time till I find out what is going on

All splines and snap rings in place no broken teeth and the Lever never moves from the locked position

I have not yet removed to sump pan / case so I an looking for tips before I tear in to it

Thank you

Cliff

I do not have the answer but that would not be a fun ride down the hill. Hopefully you have a front end loader to drop to stop the slide ride.
