I need tranny help ASAP!!!!!

Pull the top of the trans back off and inspect..........you should be able to shift it by hand if assembled right.......if you can then put the top back on and shif with the shifter, then all is good. If not you have messed up somewhere..........where, I do not know, no pic's

Im pretty certain your problem lies in how you reassembled the shift fork rod assembly on the top cover. I think you need to dissassemble back down to where you can remove the top cover again and check a few things (probably not what you want to hear but youve had enough practice at it now!). If i had to guess Id say theres a chance the roll pin in the shift fork rod isnt in far enough or is in too far and thats catching and not allowing you to grab gears. You have to make sure the flat spot on the shift shaft rod is facing you inside the top cover. Id double check the orientation of the horseshoe and the 1/2 and 3/4 inserts on the horseshoe. With the cover off and on the bench, move the shift shaft with your hand, rotate it etc as if you were going through the gears and see if you bind up as it tries to go into the gears youd be shooting for if you were driving down the street. Make sure the shift forks are oriented properly on the shaft. The downward angled sides should both be facing the rear of the tranny. If you want to take pics and or video of the shift fork cover assembly and post them Ill look at it and see if its right. If you can move the sliders into the gears by hand you should have no problem when using the shifter handle. And be one hundred percent sure the forks are resting in the valleys of the sliders when assembled.

For anyone following the post, it WAS the roll pin. So keep that in mind if you ever tear apart your tranny yourself. The shift shaft roll pin MUST be driven below the surface of the shaft but not far enough to protrude out the bottom. Glad it worked out for you. If anyone else ever needs advice on tranny rebuilds, etc feel free to ask. Brandos probably a pro by now too!
