Stuck in fwd

[Tx Jim]

I have a M4900 cab tractor with syncro-shuttle that I put in reverse and now it won't come out of rev. If the 2 speed selector and the 4 speed selector are both in neutral and I put shuttle in fwd it loads engine. It will back up in all gears. I checked shuttle shift linkage and it all appears in working order to the clutch housing. I've owned tractor for 4 yrs and it has 1452 hrs on speed/hr meter. I'm stumped. Thanks for any ideas,Jim

PS I posted this on the General forum and then decided this Forum would be more appropriate.

Will the gear selector not go into forward, or will the gear selector go into the forward but the tractor does not respond? We had a NH one time that could not shift between gears, the dealer told us the clutch plate was corroded from mud. He cleaned it up and it worked again. Since then, we have kept the clutch plate pressure washed and it has worked fine.

I had an M4700 that the linkage below the selector would jump out and not go into neutral. I had to get underneath and operate it to clear it. Maybe you have a similar problem?

You are definitely showing to be locked in two gears at once! Reverse is where you are at!!!!

I split between between engine and clutch housing,removed shuttle shift assembly and upon dis-assembly I found reverse synsonizer bad.
