Denno the reason I was guessing the tranny was I don't get any shutter in the RPM's and it doesn't feel like the motor. Tranny fluid is full,bright red and has no burnt smell to it. The previous owner only had it a short time and wasn't the one who had it rebuilt. I have a TS chip in it and thinking of unplugging it to check and the only smoke comes when you get on it hard with the HP turned up to 75.
