Mark,
If it engages, even momentarily, then we can usually assume that the valve
and pump are doing their job. So, we have to wonder why it won't stay
engaged. This is 99 out of a hundred times attributable to the o-rings on
the accumulator housing. They get hard and shrink and allow the hydraulic
pressure to bleed around the accumulator piston which acts upon the two
operating pistons.
So, pull the accumulator and R&R the o-ring(s)

Subject: [Healeys] Overdrive Ideas Needed
I have read and reread my email notes from the past 12 years and nothing is
fixing my problem.
I have adjusted the solenoid according to all my manuals ( drill bit in the
side lever of the trany}
and even adjusted a little bit past the hole and it still won't engage by
itself. I did get it to the point of working but occasionally it would not.
This was before winter and before my attempt at trying to adjust it to get
it
to kick in every time.
So now I'm back to the basics and have to reach across the trany and push
the
lever down manually to get it to engage. It has to be a hard push and even
then it kicks out after a few seconds.
The solenoid engages with a nice "snap" all the time and the throttle switch
works properly,
so I am almost there. When I had the adjustment set up a little past the
hole I couldn't
get it to kick in even if I pushed on the lever manually. ( I thought that
was
a bit strange so I
went back to the lever being directly lined up with the hole)
What a PITA this adjustment is when you do it by yourself.
The trany cover is off, I can see the solenoid engage and the lever moves
over the hole and I
can stick the drill bit in the hole per the manual and notes. I took the
valve ( steel ball, spring, rod etc.) out of the top and made sure all was
clean and free of dirt and observed that the ball did move when the lever
was
over the hole in the side of the trany.
My last ditch thought is that I am using the Redline MT90 rather than engine
oil and maybe
the trany just doesn't like this stuff for some reason.
Man these tranys suck without overdrive.
Any thoughts would be greatly appreciated,
Mark
