[Healeys] Munched overdrive

[Simon Lachlan]

Bill,
Agreed. Been there, done it, wrecked it. God knows how; the reverse cut-out
switch was working fine. (I think that, if it's a leap year and you're
standing on one leg and all your camels are looking north, you can somehow
get the thing into reverse even if the switch is apparently working.)
You may need a new main shaft as well. The end can get chewed up in the
meltdown process. Mine was so bad that
I couldn't separate my od from the gearbox. I kept thinking I was doing
something wrong/had missed the point somewhere. In the end, it took two big
chaps and a lot of brute force to separate them. (When it comes to "brute
force and ignorance", I'm better at the latter.)
Over here the cheapest option is go to a specialist and swap your case full
of shrapnel for a new/rebuilt unit.
You might think of going to a 28% instead of the standard 22% which is one
tiny ray of sunshine in the whole wretched affair.
I do, most sincerely, hope that I'm wrong and that you find a quick, cheap
and easy fix.
Simon

I hate to be the bearer of really, really bad tidings, but...

Somehow, you managed to have the car still in overdrive   and it didn't have
time
to drop out of overdrive when you placed it in reverse and released the
clutch. I'm afraid your winter will consist of pulling the engine and
overdrive, and finding a replacement overdrive or someone who has a set of
planetary
overdrive gears, because when you open your overdrive, you're going to find
a major handful of metal shards where a gearset used to be.
