Tips on removing LR gearboxes
FWIW, pulling the Landie Series 2A gearbox tip without all this hassle....
- Remove front seats, drive shafts, clutch op mech -- esp the jolly trans brake assy! etc.

Unbolt tranny from rear of engine
Take a sheet of *heavy* plywood and cut it to fit snugly between the gearbox crossmember and that immediately under the back of the engine -- ideally will be a tight drive fit. Support the center of this sheet with a suitable stand. The wood sheet should be absolutely flush with the tops of the 2 crossmembers. Doesn't have to be terribly wide -- about a foot across or so.
Unbolt yr gearbox at the two mountings at the back, remove 'em and lower gently down -- use a good bottle\trolley jack to raise the back of the gearbox. Back of the engine (flywheel case) will rest on the front crossmember and the gearbox will lie on your sheet of wood.
DRAIN THE OIL out of the tranny!
Carefully work the tranny off the back of the engine. You'll reach a point where the tranny pops off and can now be carefully slid to the rear. The wood sheet acts like a tray by preventing it from dropping down at the front. To remove completely, push the tranny slowly backwards -- the point will come when the rear end starts to pitch down past the gearbox crossmember. Once its touching the ground at the back, hop round, get underneath and a bit of pulling and wiggling will have it out and on the ground. (I'm assuming the Landie is standing on its wheels.)
To merely replace a clutchplate -- moving the tranny back on yr wooden tray about 8-12" will do.

Reinstallation. Get underneath and lift the bellhousing up until its resting on the gearbox x-member. Gently lift the back of the gearbox up whilst pushing. With luck, the bellhousing will easily start to glide forwards over the wooden sheet. A minute later and the tranny will be up nuzzling close to the back of the engine. Wiggle a bit to line up with the engine and viola! -- engine and tranny married up. Spin on the bellhousing nuts and bolts. Raise the back of the gearbox -- bottle jack -- insert and bolt down the gearbox mountings. Knock out the piece of plywood (stash for some other time!). Refit all the ancillaries. Done.
Doing a gearbox-out job this way is a pretty easy one-man venture: an extra pair of hands is a delightful luxury it available tho!! -- basically having a piece of gearbox support between the 2 x- members makes all the difference.
Good luck!

and another tip on removal. . .
I have always used an engine hoist to remove my transmissions, but my friend uses a much simpler set up. He uses a piece of steel pipe resting on the inside gutters over the doors. The seem strong enough to support the transmission. He uses a come-along to lift the transmission using this steel pipe, and he has a wheel for sliding it left and right. He runs a one man shop and this is the only way he says he can do transmission jobs alone. He can move the transmission back and forth as well when he wants to do a clutch job. Dave
