Hi everyone,
So after all the headaches I had getting my motor in with the wrong brackets.... I guess I couldn't really expect the transmission to just go in properly...

Ok I'm not sure what transmission came in this truck when it rolled out of the factory... Its a 1986 GMC High Sierra 1/2 ton Short Bed 4x4, and it came factory with a 305. So my guess is it had a 700R4 in it originally. When I bought it, it had a 350 motor with a TH400 and a NP208. They had the transmission installed without any transmission mount in between the crossmember and the adapter plate. Yes, they "drilled" their own holes in the crossmember. When I say "drilled", I mean it looks more like they used a hammer and a punch.

Ok, long story short, I forget how I took it out, and I can't get it back in. The engine is installed, and the transmission is attached to the engine. The adapter plate is on the transmission, and the transfer case is bolted onto the back of it. There is a jack under the tranny pan holding it all up right now.
I tried installing it with the transmission mount inbetween the adapter plate and the crossmember, but the transfer case hits the floor of the cab before the crossmember can get up in place. So I took the trans mount out (and put it together the rigged up way they had it), but now my crossmember looks too low. I'm pretty sure I got the wrong crossmember (as in the crossmember was made for the original tranny, and someone just tried to rig this up), or I'm doing something very wrong here.
Does the crossmember bolt below the frame? Or inside the frame?


To sum all of this up, does anyone have a picture of a TH400 and NP208 installed in a chevy pickup truck?

Thanks!
