[TR] TR3 gearbox oil leak

If they used RTV as a sealant, the gear oil has caused it to fail and it
will leak like a sieve.

Made that mistake a couple times.  It isn't formulated for gear oils
although there is an RTV on the market now that they claim is up to the
task.

It is possible, though not easy, to change the rear seal with the unit in
the car.  But if it were the rear seal leaking that badly, it would be
pretty obvious I think.  Of course, I also think it would be easy to tell if
the gearbox was that low on oil, too.  If you do this, be sure to inspect
the sealing surface on the flange, and use a Speedi-sleeve if necessary.

I did have one A-type OD that started leaking pretty badly at the adapter
plate, I think because a piece of gasket blew out (possibly because the
plate was distorted and didn't clamp the gasket evenly).  I managed to
mostly stop that leak by draining the gearbox, cleaning the area thoroughly,
and then heavily 'buttering' the entire gasket area with Permatex "Ultra
Gray" RTV.  Used the whole tube as I recall.  Let it dry thoroughly before
refilling with oil.  It was still working some 6 or 8 months later when I
replaced the entire gearbox & OD.
