So I recently removed my transmission and had it rebuilt not Ive got it back in. But I cant seem to get the cross member to fit back in it was a pain to get out and seems like it will be worse to get back in. Anyone have any ideas that make could make it easier?

 

no personal experience, but i think the official tool is a frame spreader. unofficial tools are a big hammer, or drive in a 4x4 or maybe rig up a bottle jack or an old fashioned bumper jack to spread the frame rails a tad.

 

Is the rubber isolator(not correct name) still attached to the crossmember or the tailshaft?
Remove it.
The crossmember needs to be installed from above & pulled down into position.
Should still have enough room to slide it in sideways then pull down with the isolator off.
Get all 4 bolts in one end(dont tighten) then persaude the other side down & get the other bolts in
Or just do what dhvaughan suggested & spread the frame,,,,,cant believe I said that lol

 

Well, when I replaced mine, i just used a big *** hammer, put it in catty-corner, and hit the hell out of it until it went into place. could do that, then take a spud and line it up to the bolt holes.

 

There is a certain way which may take hours to find but once you find it will slip right in or you can help it in with used of BFH

 

put it up above the back of the transmission where the frame is wider then tap it foward and down it goes in pretty easy this way

 

Here's the way I did it. I got a bottle jack and a 4 x 4 and installed it between the frame and pumped on the bottle jack until it freely went in. Just my 2 cents though...
