I'm having issues with my 9870 . It has the pro-drive transmission. When going down a steep grade it will speed up too much then shift down. To the point it almost will pull the rear tires off the ground. It's like something is letting the oil bypass somehow and letting it free wheel(coast)and not slow or hold the machine back. Has anyone ever had this problem?
