I know there are plenty of these threads out there already, but my problem is a little different. I can start the machine and run it for about 20 minutes to a half hour, and it shifts fine. Then it'll just all of a sudden decide to do the flashing number and stuck in gear thing. I can shut the machine off to try to reset it, manualy shift it into neutral to try to reset it, and it wont work. If the machine sits for half hour to an hour, it'll start up and work fine. Anyone have any ideas?
