2018 Coleman UT400 Trans keeps popping out of forward

[dman66]

My buddy has a ut400 that the forward gear keeps popping out of gear. She only has like 400 miles on the odometer .the shift cable has been adjusted and the shift lever has been updated / modified. All other gears are good. Is there an internal detent cam or something that wears out or shift fork that can be replaced ? Or is there some other magic that I can perform ? Looks like the engine needs to be split.

THis might not be related.  I have a 550 UTV and I use primarily the low forward gear.  This means the shifter must be pushed fully upward.   I noticed that there is a very slight "click" and a final movement if I hold the shifter all the way up as I begin to move the UTV.  As if it is not quite fully engaged without that last extra push as I give it a little gas.   I also found that some UTV dealer (Hisun/Coleman dealer) had a video pointing out this very same thing.   Like I said, may not be the problem you have. Good luck.

This is the issue, it is a know issue that Coleman will not deal with.  Go to this post to fix the issue.  I did this, but it was to late of a fix and now I have to replace the transmission.  Gear are "F*^ k e d"
