Sorry, have'n a tough day,
You ain't worked on too many cars right?
Do you plan on doing more work to the car? If so then get an assembly manual for your year/model, not a chilton or haynes,
there's an O ring or two where it slides into the trans, you may have to remove the speedo gear to get to one, I maybe wrong, been a while and I'm easily confused.
I'll run out to the garage and check my magic book.
