You guys are funny. A LBC without an oil leak is an LBC with no oil in it.

Somebody else will have to tell you if your tranny is built like this, Ed but if it is this is what it'll look like. What you can't see is an oil seal in the front cover that surrounds the splined input shaft, and a gasket between that cover and the case. There is also a gasket between the countershaft end cover which is out of sight but located just below the front cover. If you are leaking tranny fluid any one of these 2 gaskets or the oil seal could be responsible.

Not exactly like that, but very close. Here's a diagram showing the gaskets & seal.
The seal is the most likely culprit IMO, but it's worth noting that the washers (9) and (13) are supposed to be copper sealing washers. Since the threads go through into the inside, an ordinary flat or lock washer can cause a leak.

These illustrations give me a much better idea of what I am seeing and what may be causing the problem.
I wrote earlier that I put about 10 oz of Lucas Transmission Fix in the car and drove it on Friday for an hour or so, but saw no particular change in the oil leak. I drove it again yesterday, Saturday, and the oil leak was considerably reduced. But this may be because I drove the car for only about 15-20 minutes. I'll try again tomorrow for about an hour.
If the problem is not with the transmission, I may try the Lucas product that is meant for "fixing" engine seals. Normally I wouldn't try such products, but these Lucas products contain no solvents (or so they advertise).
Since the engine was rebuilt only a year and a half ago, I'm hoping the seals are still in decent shape.

Randall,
I thought so. But when I had my engine rebuilt, the shop put in "modern" seals, which I assume are fiber seals. In any case, I am still experimenting.

I thought the rear main seal is a rubber type lip seal? At least in a TR6

Not for a TR2-4 (unless you "upgrade" to an aftermarket seal).
