Hisun 700 shifting issues in high

[Julie Doeppke]

We bought a Hisun 700 UTV, used. It has an issue when you run it in high. It drives but acts like it is shifting when you get around 35mph. Clutch looks good. Read many articles and not sure transmission or something in rear of UTV. Looking for any advice.

Sure sounds like a transmission. Have you made sure the transmission is full, of the correct fluid? And if it's a wet clutch, that should be topped off with the correct fluid also.

If it runs strong up till the 35 or so, before the problem starts. And there's no noise coming from the rear differential. I'm leaning towards it being a transmission issue. If there are any belts involved, that's another possibility.
