933f forward/reverse adjustment

I've been running my 933f with no issues until recently. The forward lever pops out especially under a load. Is there adjustment for this or do I need to look at the interlock mechanism? The manual shows this but no directions on what needs done to repair it. Thanks

Not familiar with your machine, but taking a guess this is not a power shift transmission? I had similar with a 9u D6, jumping out of low. I removed the interlock from the side of transmission as it was much less work than removing transmission. Nothing jumped out as worn. Cleaned and lubed all the lock pins, and put it back. It solved my problem.

Working on a loader nothing is easy, unless you like playing monkey (hanging from one foot, head down in hole). I wish you luck, and just maybe someone that has been there done that will chime in.

Thank you Ray. I bought this machine with issues in the finals. After almost a year it was up and running. The machine is strong but after it pops out of forward, I have to kill the machine to re-engage. Hard on the machine and me too! Seems like it is getting worse.
