downshifting maybe? the trk is staying in higher gears longer and doesnt go down into first unless your under 15mph i think. mine acted stupid like that too for a bit then when i let off the gas it freewheeled and when i resumed cruising it would be in 3rd, then 4th. im going to an m50d in mine if i can find one for my 3.0 4wd.
