Transmission Swap - HELP!!

Buy two long 2' socket extensions, and a wobble-head socket sized to the bellhousing bolts. It makes removal and installation much easier whether you're using an air ratchet or hand tools.

Never, ever use the bellhousing bolts to pull the trans onto the engine...the trans housing is aluminum and you will break it. If it won't push flat against the engine by hand, it's not aligned right.

Do what the other guy said regarding the torque converter. Pour fluid into it until it's full, then slide it onto the trans input shaft while gently rotating. Keep pushing in and rotating to ensure it is fully seated...it's possible to mount the trans w/ the converter not engaged to the pump, and you'll destroy your new trans.

Get a flywheel turner tool, only costs $15 or so at NAPA and you'll be glad you have it when removing and installing the torque converter bolts.

Use an accurate torque wrench when installing the bellhousing bolts and torque converter bolts. I like Loctite thread locker (blue for bellhousing, red for converter).

Find the torque specs for the bellhousing and converter bolts. They're in the Haynes/Chilton manuals. Mine's in the garage and it's freezing out there. Probably posted here somewhere.

Brake parts cleaner is great for cleaning bolt threads, grab a can while you're picking up the extensions/socket/Loctite/etc.
 
Sorry this may be a silly question. I thought the torque converter was already installed on the new tranny...if thats the case how do i slide it on the trans input shaft? Does it just slide with the transmission or do i detach it from the transmission?
I really think a Haynes/Chilton manual would be a good investment before you dive into this project.

The torque conv just slides onto the input shaft, but it has to engage the pump. The pump may or may not be aligned w/ the converter as you're installing it, thus the need to rotate the converter while gently easing it inward.

I was under the impression you were getting a used trans and torque converter from a salvage yard. If so, the converter may or may not be properly installed onto the trans when you receive it.
