Okay so I have checked for codes a few times now and dont get any. After checking for damaged or loose wires I could not find anything out of the ordinary. after repeatedly pressing 4 hi it suddenly locked in and i can switch from 4 hi to 4 lo BUT NOW IT WONT GO BACK INTO 2 HI. when you press 2 hi the light blinks twice , you can hear the shift motor moving but it goes back to 4 hi. Maybe this narrows it down to a weak shift motor?
