I rebuilt my 94 yj transmission because when I bought the jeep it was grinding when shifting into 2nd and when downshifting in all gears. I found my shift dogs for 1st and 2nd lying in to bottom of the case and synco were shot. Now that I have it back together and installed my problem is when I’m at idle I can shift in all gears and downshift fine once I take off and go from 1st to 2nd I can’t get in gear, I can put it in 3rd thru 5th and downshift back to 3rd but it won’t downshift into 2nd or 1st until I’m almost completely stopped. I’m completely baffled
