1.) You can pull the gearbox without pulling the engine. You will have to
remove the seats, carpeting, and parcel shelf. Then you will need to
disconnect the hand brake cable underneath the car so that you can remove
the fiberglass gearbox cover.
2.) The OEM synchros wear out quickly and some of the ones on the market
did not work properly from the start. Buy a set of uprated ones from
British Car Specialists (NFI) or other source that checks out the quality
before they sell them.
3.) While you have the box out you might as well replace the first and
third motion shaft bearings and the O-rings, and the accumulator piston
rings on the overdrive. These last items can be replace with the gearbox in
place, but the task is easier when it is on the bench.
When you unbolt the bell housing from the rear engine plate, pay attention
to where each individual bolt goes. Two of the bolts are "dowel bolts"
which are required to precisely position the gearbox so that the first
motion shaft lines up with the crank shaft.
When reassembling, be sure to put some grease on the pilot bearing.
Good luck,
