>Are there any owners out there who have 'upgraded' from the 4 speed to
overdrive? Is it only worth doing when you need to replace the transmission
anyway? Or are there no longterm problems caused by cruising at highway
speeds with the regular transmission?

If you buy a ready to use overdrive transmission then it is just a
transmission swap. About the same amount of work involved in changing out
a clutch. Since you have a 74 model you can use either the A or J-type and
since the J-type are easier to find and have a less broad application (in
the TR world) this is what you are more likely to find. You will need the
column switch, a new switch plinth and a wire harness, all of which are
available from the parts suppliers. And a right angle speedo drive (unless
it comes with the transmission ).
I haveconverted a transmission and it is much more wirk. It requires a new
mainshaft and since almost everything is assembled to the mainshaft it
requires an almost complete teardown.
