The towing concern people have touched on (disconnecting the drive shaft)
depends on whether your LBC has a traditional "splash" gear oiling system
or a gear oil pump. Some cars have a gear oil pump in the transmission to
circulate oil (I'm thinking the 5 speed TR7/8 may have a pump), and this is
driven off the engine power input part of the transmission. Flat towing a
car with a gear oil pump does not power that pump and does not circulate
the oil in the transmission, which starves the tranny of oil and ruins the
transmission. This type of car tends to be newer, in general, and may use
ATF in the manual transmission. As Jim says below, the TR6 has a tradition
splash oiling system.

Towing a TR6 will not damage the transmission. The gear oil is
'circulated' the same way that it is when the car is being driven, since
the constant motion shaft is still turning the countershaft when in
neutral. This may not be the case on all LBC's, but don't concern
yourselves with your TR. I would say that towing one with a dry tranny
will ruin it as fast as if you drove it that way.
