Graham:
There are two A type overdrive trannies on eBay at the moment. You
can
also contact Quantum Mechanics (www.quantumechanics.com) for a rebuild unit.
The simplest thing to do is going to be a swap with an overdrive
tranny, although you could buy the overdrive separately and add it on.
This is not for the faint of heart, however, as you would need to swap the
mainshaft for the overdrive version, add lockout switches to the top cover,
and add a speedometer angle drive. This is enough work that you would
probably want to do an overhaul while you were at it.
Cheers,
Vance

Subject: look ma, no overdrive!
I was deep in the bowels of my 72 TR6, trying to discover why the overdrive
didn't work when I discovered the problem -- no overdrive unit!
I would guess at some point the previous OD had blown up, and rather than
replace it, some DPO merely installed the non-OD transmission extension. The
car was OD originally -- has the switch, badge and wiring.
So ... where do I find an A-type OD without a core to exchange? (It's
A-type, right, for that year? Also, is it the same A-type that's found on
some other European cars of that era -- Volvo, etc?)
Also mulling whether to buy a rebuilt tranny and OD as a unit ... existing
tranny has GREAT synchros, but is very noisy when idling in neutral.
Thoughts, o wise ones? (beyond to look under the &*^*&^*(^! car the next
time to see if the OD is there!)
(BTW, I bought this car on E-Bay about a year ago from a small dealer ...
I'm pretty sure he didn't know the OD was missing, and he had fully
disclosed to me that the OD was not working -- ie nothing happened when he
drove it and flipped the switch.)
