I noticed while riding yesterday that when taking off in high it will lurch like something is possibly slipping. It will do it 2-3 times until it picks up some speed. Low and reverse do not do this. Belt seems to be fine based on sound, no squealing. Within the last 50 miles I have changed the rear fluids with OEM Polaris fluids. I thought maybe it was low, but if anything I had slightly too much and let the excess flow out.

Anything else I could look for or check?

Thanks
