have longer stalks than the TR4 switch, I cannot confirm or deny this

other differences.
Michael (who now knows more about TR4 o/d switches then he ever wanted
to
know)
ISTR the column switchgear as a whole on 5/250/6 had shorter switch
stems and probably brought about because these cars had smaller
diameter steering wheels (I think). Those on my 1966 4A were
definitely longer (probably an inch?) than the many later models which
I drove but never owned long term
But on the issue of overdrives as a whole, you guys have a lot to
answer for <g>
Not so long ago, there was discussion as to whether the O/D should
engage gently or with a thump, should you use/not use the clutch?
I had sleepless nights about this!
Then, last weekend I trundled around the hills and dales of west
Wales. This was in an ancient but very original and tired 2000 with
180,000 on the clock. About 20 of her original 95 horsepower was on
permanent vacation and oil was going down the valveguides almost
faster than I could pour it in at the top. But her overdrive was a
dream. Instantaneous in and out, no thump, quiet and the car still
delivering about 32 mpg at cruise which with our gas prices is an
important consideration. D'you know - it was just like it always was
and I'm now really rueing the day that cars as a whole went to
straight 5 speed boxes. Then, on getting home, I went out for a blart
in CG to measure the contrast. Instanteous, quiet but a hearty 'thump'
on engagement - and that's just like it always was as well, so why
worry? Long live the 'A' type!
