There was nothing to really fix persey...In my situation the reverse issue was intermittent. I bought my sled in march of last year so I didn't get a lot of time on it however, I noticed intermittently that when the machine was cold and I would start it (let it warm up) and hit the reverse button nothing would happen. Drag it of the trailer drive it forward about 20 feet and I had reverse all day. Drive it up on the trailer go home, go to take it off the trailer sometimes it would go into reverse sometimes not. I told the dealer that some off the posts that I had been reading on different forums suggested that the "reverse issue" may be the result of the TPS being out of spec. He told me that he hadn't heard of any of the 16 sleds having a reverse issue and to bring it down. He hooked it up to the digital wrench and everything was in spec...(and while I was down there as it would happen it went into reverse just fine). He told me if it acts up this winter to drop it by. When I got home and went to take it off the trailer guess what...no reverse....Being a fan of dielectric grease and having greased most of the connectors as a precaution anyway I traced the reverse switch connector inspected it and added dielectric grease...in my opinion the connecter is cheap, white plastic and it really wasn't a tight connection. Meaning it doesn't "click or lock" together. However, after adding grease firing it up multiple times within the last month or so the switch has always worked. Bad connector? Luck? Idk, but for now the issue seems to be resolved hopefully for good.?
