      Remove the transmission mount crossmember first for much improved access to the shifter (and note any shims/washers that come out with it).

        The shift linkage will have to go. Remove driveshaft early on for easier access to the rear trans mount bolt. Lose the cross mount asy & speedo cable. Even at that, it doesn't exactly fall out. Dennis

            Remove the driveshaft. Support the engine, and remove the transmission mount. Remove the speedometer cable. Lower the transmission, but not so much that the fan hits the shroud, or the distributor shielding hits the firewall. You can then get at it. Lowering the engine/transmission lowers that end of the transmission some out of its tunnel. Little fingers help.

            Support the engine with a "saddle" made to bridge the oil pan and support the weight from the block/oil pan rails. I then use a scissors jack to lower and raise it after I remove the mount/crossmember. You could jack on the oil pan, but you risk denting it. Those things are expensive. Look up "saddle" for messages by John Hinckley in the archives for directions and pictures on how to build this. To summarize, the saddle is made from 1" x 6" pieces of lumber forming a "U". Get the picture. It tells a 1000 words.

              Here's the "saddle" - 2x6 base, 1x6 sides that snug up to the sides of the pan, 1" higher than the depth of the pan. The ultimate low-cost tool
