I'll start a wiki:
Get a pilot tool for location of clutch disc.
With car raised on stands:
Disconnect battery
Remove seats & shift lever. Remove both tunnels. Disconnect overdrive wiring.
Cover car floor between center and passenger door with plywood (for sliding transmission across floor)
Disconnect driveshaft from trans (and axle if necessary).
Remove starter motor
Disconnect clutch linkage from bell housing operating lever (this is a 4-cyl, right?).
Support rear of engine (undo throttle linkage if necessary).
Support transmission with floor jack or transmission jack.
Loop old fan belt around rear of trans as a handle.
Undo rear transmission mount from under the car
Undo and remove bolts around engine plate. Note which are dowel bolts and placement of bolts as they are different lengths .
Do not allow trans to hang from first motion shaft. Make sure engine and trans are both supported when you're disconnecting the trans. I was able to insert a wood block between the valve cover and firewall which kept the engine from tilting backward. It pretty much balances on the front motor mounts.
It is possible to pull the trans rearward into the passenger compartment and slide it out the passenger door. You need plenty of pieces of wood to support it and to protect the carpet. This is a two person job.
With the trans out, you'll be looking at the clutch
Now for the humor:
Re-installation is the reverse of removal.
