Ok so I bought this 04 foreman es and when I got it, it only had first and reverse. I ordered a shift angle sensor and shift motor. While waiting on my parts to arrive I decided to just putt around the yard on it in first gear and now when I try to electric shift or manual shift it to 1st it springs right back to neutral. I can get it to stay in first as long as I take off as soon as it shifts but as soon as I let off the throttle it goes right back go neutral. I have now replaced the shift motor and angle sensor and still get the same results. Can anyone give me some tips on what might be going on. I'm stumped. Thanks
