Remove and install new transmission 904 auto

Add to list above, disconnect battery neg. cable and remove starter. You need to rotate the engine to get at each torque converter bolt. Use a socket at front or a screwdriver thru the starter hole. Mark one bolt location on torque converter & flex-plate (paint or center-punch) since they only fit one way.

If you drive the front up on ramps, you will have room to work below, or you can support it on the frame rails. You don't need a lot to secure the engine since it will still be on the front motor mounts. A wood 4x4 across the inner fenders works (rags to protect paint). It is hard to get at the top bolts unless you lower the tranny a bit (remove x-member). Ratcheting box wrenches might help a lot. I have wrestled out a tranny by hand, supporting it a bit on a rope between the torsion bars, but now have a scissors transmission jack from Harbor Freight which makes it simple (good for many things). The transmission only weighs ~150 lb, and much less once you pull the torque converter.
