190 XT

My AC 190xt likes to jump out of high gear when decelerating. Have read they do it in 3rd gear. Mine is fine in all gears except high. Don't use it much but would be interested to what causes it to jump and what is the fix. Thanks

Wear in the shifting collar(s) from use and/or abuse. A major split and replacement of parts is the cure.
I worked at an AC dealer when the 185- 200 tractors were new. In an effort to avoid major repairs, I was tasked with tweaking problem tractors. Welding, grinding, moving, deepening, etc. the detents in the shifting rails was one trick. Another was doubling up detent springs. it's kind of tricky, trial and error work.

I agree with Bob, I've ground out the front of the shift rail notch and weld the back to move the fork ahead a little. It's a cheap fix if it works. You can always put new parts in.
