2004 Rancher 400 ESP/Auto trouble

Hi. New member as I just purchased this ATV. Thanks in advance for any info. I have already seen the extensive write up in the stickys but have a few questions.

The atv will not go into Auto mode no matter where the switch is located.

It cranks and runs great. Shift into to drive and the gear shift indicator just shows "–". It drive fine in 1st gear but will not shift and still just shows "–".

When you put it in reverse sometimes it drives fine other times it bogs down the backfires and quits. After this if you recrank it it does the same thing. The guy I bought if from showed me a "reset". Hold down both shift buttons turn on key. Immediately let go. Then push up, down, up. The shift motor actuates, then push in throttle, let go of throttle, start the atv put in in reverse and it runs fine.

Is this something the recall was meant to fix?

I looked through the service manual and it has a process for retrieving codes, but I was not able to retrieve any. It seems like there are a lot of people that have issues with these trans. Any thoughts would be much appreciated
