<p class="MsoNormal" style="margin-bottom:12pt">UH OH! that is your slugglish
issue! I would drain that oil (for rear ends) and replace it with the 30W ND.
That rear end oil foams in the annullus and plays hell with the spring pressure,
passage thru the system and fast clutch engagement. Check it out on the
web...that heavy fish oil is not for British Trannys. If you put the heavy stuff
in to stop leaks, that's not the answer; neither is synthetic-too thin.The
gearbox and OD were designed to run on conventional oil...ancient as it may
seem. Yes, a small air compressor is enough of a blast to clear passages.You
will probably hear the clutch pistons engage if air is put on the valve
opening. If you remove the spring, ball, and plunger with a magnet, you
can then extract the valve and run a small wire down the middle to clean it-then
a blast of air-be careful to not get any lint from a shop rag into the mix. Upon
rebuilding a unit it is "suggested" to carefully enlarge the valve hole to
1mm (but cleanliness is probably best solution). The new pistons sold
today, and made by Overdrive Spares, (old Laycock group) are equipped with
rubber o-rings. Good that you replaced the tire bushings! Hank<u></u><u></u></p>

<p class="MsoNormal">Yes thanks for the tip. The problem is slow to engage. It was
suggested maybe accumulator O ring. Just did pull the check valve and all. Did
seem like dirty oil. I cleaned it all up. I’m already committed to extracting
the accumulator and piston but wanted to replace all the tranny mounts and
bushings which I did. Mounts were pretty squished and cracked. Bushings(radiator
saver)were fairly solid but were replaced. They were the original.
Cleaning and degreasing as I go along.<u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal">If(?)it is the O ring or rings, I guess they are metal on the
piston, I might just spring for a uprated from Dennis Welch or AH spares has a
combo housing/piston both which have rubber O rings. <u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal">Working my way to the extraction part. I want to use forced
air through the operating valve but I only have a small air compressor for
tires. Some kind of extraction tool would be helpful. (18G182) I have always
changed tranny oil regularly. Used ND 30 early on. Using MT 90 now for many
years. <u></u><u></u></p>

<p class="MsoNormal" style="margin-bottom:12pt">Warren- Don't know the OD problem
you are experiencing, but suggest before you tear into it, undo and clean the
check valve and ball on the top right side (if you haven't already done so). One
small spot of dirt lodged in the valve drilling can kill the hydraulics and make
it seem like a bigger issue. It may be worn parts, but, if not, this is an easy
first test. If it is dirt; good idea to change oil and add fresh SAE 30W
non detergent oil to the unit. Regards, Hank, <a href="http://healeyhelper.com" target="_blank">healeyhelper.com</a><u></u><u></u></p>
