[Healeys] Overdrive install advice needed

[JSARCH]

I used non harding hylomar. BTW, it is extremely difficult to install the OD
onto the transmission if it is in the car. I would suggest removing the
transmission and mating it to the transmission with it in a vertical
position; bellhousing facing down. However, the assembly is very heavy to
reinstall into the car and it is best accomplished with two people. It can
almost be easier to remove the engine and transmission, install the OD and
then reinstall the engine/trans/OD back into the car.

Hi all

 

Thanks to much help from this list I was able to diagnosis the problem with
my overdrive.  It turned out that the overdrive solenoid had become non
functional.  Since I already had the transmission tunnel off and since the
overdrive has not worked properly for over twenty years I decided to get a
new rebuilt overdrive. The only question I now have is, how is everyone
dealing with the gasket between the overdrive and the tranny and the gasket
for the cover over the solenoid mechanism.  I haven't done any major work on
the engine since the early 90's when I rebuilt both the engine and the
tranny, and do not remember how I dealt with the paper gaskets. I've heard
that permetex is good, but there are different types of permatex. So what do
most of you use? And how do you use it.  BTW I was able to get 30 weight non
detergent oil at my local advanced auto parts store, so that problem is
taken care of.  

 

Thanks in advance for any advice you can give me.
