Re: Sm420 install

Done this R&R too many times over the years

Best trick I can share is to get a long grade 8 bolt the size of the 4 bolts that hold the trans to the bell housing (can't remember the size off hand). Then cut the head off the bolt and screw it into one of the top bolt holes (left I think). Lay trans on its side on your standard jack and lift it up enough so you can slide the upper hole of the trans onto the bolt. It's now supported and you can rotate it by hand to get the input shaft to line up and push it home.

Don't forget to leave trans in gear before you pull the stick off, that way you can rotate the shaft with the back yolk to get the splines to line up with the clutch splines.

Used to be a one man job when I was younger. Now need to have my wife on jack duty.

Good luck, and be careful! That sucker is heavy.
