Why won\'t my 4 speed go into gear? Is it possible to incorrectly install the top cover of an SM 465 so that it won't go into gear at all? I know the front and rear forks were on correctly, but I'm not completely sure about the reverse since I can't see. My truck doesn't have a bolt-in tranny hump so I'm working in a confined area and I refuse to cut the floor out of my truck. I just need to know why you guys think it won't get in gear now. I honestly wish I'd known how to get the shifter off before I'd pulled the top cover as now it wont work at all. GRRRRRRRRRRR!!!!!!!!!!!!!
