I took a tranny out of a an sdl in about 2 hours. I used an 88 300te for the doner transmission, and it was much more difficult. The clearance for the wagon was much tighter, and getting the bolt out of the housing took much more time.
When I did this I didn't use a lift, but just used jack stands. I also made a jig for the foor jack to hold the tranny.
I still have this parts car, if you need anything, let me know.
