Bob is on the right track. When I first got my '90 Montero the auto shift was very sloppy. I did what Bob said and found some worn out bushings. I imagine the dealer could sell you some new ones. I found some in great shape at the local wrecking yard. <img src="/forums/images/graemlins/kewl.gif" alt="" />
