[Healeys] More Transmission/overdrive questions

[Williams, Allen]

A lister sent a link to a youtube video on the rebuilding of an OD. The
rebuilder said there was originally no gasket on either side of the brake
ring. My unit confirmed that. There was some type of sealing agent used, so
that's what I'll do with mine. Someone has already mentioned a metal to metal
sealant they use, albeit not nessarily on a Healey.
I am certainly no expert on the workings of these units, but if it is slow to
engage, the first thing I'd check is the dash switch. Mine occassionally takes
a mind to engage leisurely when I flip the toggle switch rather than make
immediate contact.Also, I'd verify the relay and throttle switches were not
corroded and working properly. Also, make sure the solenoid is working as
intended. After that, it could be an oil pressure problem caused by an
obstruction, or internal seals. If you can get the oil drain plug off the OD,
you can check the magnet and filter screen for clogging. When I opened mine, I
was shocked at all the goop that was in there including all the gold colored
particles mixed into the oil. I think some would be present from normal wear
and tear, but how much, I don't know.

Subject: More Transmission/overdrive questions

I had my overdrive & transmission rebuilt by Quantum Mechanics approxamately
4-5 years ago. Initially, all was well, however recently the overdrive has
developed a leak between the brake ring & either the rear housing or the main
housing. I cannot tell if there are gaskets between these parts. There is
evidence of some kind of sealant. I have verified that the nuts are tight
around these components. As far as I can tell none of the gasket kits
available for the overdrive include a gasket for these two joints. I know I
could make a gasket but I would like to know if any supplier sells this gasket
either separately or in a kit.  What is the best sealant for this
application?
Second issue. Originally, the overdrive shifted into overdrive nice & crisply.
I drive about 6000-8000 miles per year. I keep the transmission topped up with
the appropriate oil. Recently, the shift into overdrive has become sluggish.
Initially, when the car is at ambient temp. (80 degrees) the shift can take as
long as 2-3 seconds. After it is warmed up it takes about 1-2 seconds to
engage. I have verified that when engaged an appropriately sized pin can be
inserted into the lever & alignment hole on the side of the O.D. Do you have
any thoughts on what may be causing this?
