You can try calling/emailing these guys in Atlanta and asking about an M47 ...you may get lucky.

Meanwhile:

You can try this to get a few more miles out of it.

Drain the trans fluid into a clean pan...a light colored cat litter pan will work just fine.

examine the magnet on the drain plug and on the filler plug.
examine the fluid --- sliver/steel shards on the magnets and in the fluid = gears.
Brass finer particles in the fluid---shimmery = syncros.

this will give you an idea of the damage done.

Refill with a Sythetic Manual Trans fluid. Redline MTL is one choice---2 qts + some.

Your your daughter can probably drive it for a while avoiding 5th gear, which is at the back end of the tranny and dosen't come into play. 4th gear is 'direct drive' aka 1 to 1 ratio. 5th is the Overdrive.

Another double step is to refill it with cheap ATF--Type F and drive it, drain again after a 100m or so into that cat litter pan and see what's floating around.

Then if the fluid and the magnets are not too contaminated. Refill with Redline MTL and drive it until you work out a replacement solution.

Just keep it out of 5th.
