What I was told was last fall it would not shift/light/ect. He replaced the battery, he would start and let it run for 5 minutes, shut it off and then it would work fine/clear itself. He told me it slowly got to be a longer before it would clear itself. They put it away last fall and late this spring he couldnt get it to clear itself, it stayed in 1st and all the lights stayed. He didnt mess with it this summer and just decided to sell it. Thats when I bought it and I am just starting to diagnose it.I Thought I would start with this site, the guys who have been there, done that. So as far as I know its been less than a yr but he really never tryed to dig into it.
