I just purchased a used (250 hrs) worksite model and outfitted it with a Curtis soft cab and overhead console. I haven't been able to use it much yet, we still have too much snow. But I have noticed that it is very difficult to shift through the gears especially when shifting from reverse to low or mid. Sometimes when backing up it doesn't want to stop and keeps inching along unless I shut it off. I've read that changing the transmission fluid and filters helps. Any other ideas???</P>
