brown, welcome to TBN. 
The description of the problem is vague, but since it "feels" different in 4WD, it sounds like a tire slipping on the ground or a wheel slipping inside the tire. If the tires are aired-up, you can chalk a reference mark on wheel/tire to see if the bead slips.
Provided you have enough hydraulic fluid, seems unlikely anything is "starving" the HST after only 200 hours. If you search on BX transmissions, you will find they generally either work fine or don't work at all. We basically just keep clean oil and filters and pray to the hydraulic gods. There really isn't anything else to adjust or maintain.
