There are only so many (or few) places for oil to leak from the gearbox.
I have my doubts that that is the problem.
Can the underside be cleaned sufficiently to have a 'clean' look to it from
the below?
If so, I suggest cleaning it, topping up the oil and take it for a very
short drive - enough to engage the overdrive.
Park the car overnight on some clean newspaper or something else to see
where it is leaking.
Then put it up on a lift and see if you can then see where the oil is coming
from. Oil spots on the paper are 'bread crumbs'
Possibilities -
Make sure all bolts on oil pan and gearbox are tight. If oil is coming from
one of the bolt areas - gasket could be torn?
oil pan warped and seeping out that way?
Rear oil seal?
If not the oil pan or loose bolts - no way to do anything but pull gearbox
and maybe engine.

Subject: [TR] TR3 gearbox oil leak
What do you all think about a car (fortunately not mine) with a supposedly
rebuilt overdrive gearbox but which is leaking a cup and a half of oil every
200 miles?
The owner insists it is the gearbox and not the engine, although the leak is
hard to pinpoint.
I must confess my ignorance of gearboxes as I usually send them out to be
rebuilt by a guy I really trust.
So my question is, is there any type of gearbox leak which is amenable to a
fix other than pulling the gearbox out ?
