*Correct diagnosis is 1/2 the repair!!*

First you need to confirm whether the clutch (on the flywheel) or the
overdrive is causing the slippage.
To do this you ABSOLUTELY MUST disable the overdrive as a badly misadjuster
overdrive operating valve can produce similar symptoms.
To do this I would remove the overdrive operating valve completely. (There
are other ways but this is absolutely definitive).
Now drive the car up a long hill where you are amle to use full throttle at
around 3000 RPM (maximum torque) for a few seconds. If it is the clutch (on
the flywheel) that is causing the slippage these operating conditions. Test
this a few times to be sure.
If there is no slippage we have confirmed that the overdrive clutch is at
fault.

Step 1 completed. Please report results.

Agree - I had to re read your note to be sure which clutch you were talking
about.
If you have the GB cover still on you, could disable the OD by
disconnecting the solenoid - probably easier than removing the operating
valve.
Regarding testing the OD relay, yes as MS says they usually fail positively
and usually the operating coil.
To bench test:
With a 12V supply on W1 and W2 you should hear a clear click for ON and OFF
This would prove that the coil is OK
Contacts not quite as easy to verify.
Same test as above but an ohm meter on lowest scale across C1 and C2
An anologue meter is preferable and you can see if there is any dithering
when the contacts close. Operating should be positive and crisp.
I would also be suspicious of the TS - they can have some weird failure
modes and go out of adjustment,

Alright=E2=80=A6thanks for the replies so far. Still trying to get all =

And again, how to bench test a solenoid?

Correct diagnosis is 1/2 the repair!!

=20

First you need to confirm whether the clutch (on the flywheel) or the =
overdrive is causing the slippage.=20

To do this you ABSOLUTELY MUST disable the overdrive as a badly =
misadjuster overdrive operating valve can produce similar symptoms.=20

To do this I would remove the overdrive operating valve completely. =
(There are other ways but this is absolutely definitive).

Now drive the car up a long hill where you are amle to use full throttle =
at around 3000 RPM (maximum torque) for a few seconds. If it is the =
clutch (on the flywheel) that is causing the slippage these operating =
conditions. Test this a few times to be sure.

If there is no slippage we have confirmed that the overdrive clutch is =
at fault.

Step 1 completed. Please report results.=20

You may recall the very extended overdrive and clutch saga last year. =
Long story short(ish)=E2=80=A6

Stymied as could not get pump out. Turned out to have been =
=E2=80=9Cfixed=E2=80=9D at some stage with some form of =
=E2=80=9Cchemical metal=E2=80=9D which was coming loose/apart.

Why not a new clutch I thought? Sensible while you=E2=80=99re in the =
area looking at a 30+ yr old item.

New clutch=E2=80=A6no good. Noisy, wouldn=E2=80=99t =
engage/disengage/play at all.

Gearbox out again.

Turned out that the new clutch kit was defective. (Thanks Mirek) =
(Genuine B&B from AHSpares).

New one did work.

All=E2=80=99s well for first 10 or so miles. Then the dreaded =
slippage(?) starts. But it=E2=80=99s not quite the same. Reminds me more =
of a slipping clutch. (But NO smell)

Yes, plenty of oil. Over the full mark. Looks very clean. Pretty sure =
it=E2=80=99s 40wt non-detergent topped up with 30wt non-detergent. (Or =
vice-versa). Am confident in state of the filter, magnets etc.

No, I have not pressure tested it yet and yes, I dread restarting the =
whole bloody process all over again. I=E2=80=99m not sure I can face =
taking the box out again once, let alone multiple times.

What I want and experience tells me I=E2=80=99m unlikely to get is a =
miracle cure!

One initial question=E2=80=A6..do OD relays either work or not work? ie, =

First thing to do as per MS is to identify which clutch is slipping.
Regarding testing the solenoid, not as simple as the relay.
They have 2 coils - a holding and pull in that is disabled when engaged by
a small switch.
I would suggest leaving it attached to the OD with cover off.
Pull the wire off the GB 3/4 switch and feed directly with 12V. The
solenoid should move the operating lever positively. Check for full motion.
There is supposed to be about 10 thou shaft end float to avoid binding.
If you have a dc ammeter then you should see an initial current of around
18A from memory then almost immediately dropping to around 3-4A. It should
also drop freely when off.
Do check the TS.
Good luck

Yes the solenoids can cause all sorts of problems.
Around the time you last worked on your overdrive OD Spares were having
problems with a batch of solenoid as I recall. May want to check with them.
If the "pull" coil or points in the solenoid have burned out, usually
because the adjustment is done incorrectly,  the hold coil will have
insufficient power to move the solenoid armature to the "engaged" position
consistently.
After you have confirmed that the vehicle clutch ( the one on the flywheel)
isn't slipping it's time to move onto checking the overdrive.
You can eliminate the possibility of problems within the unit by manually
engaging overdrive by pulling up on the setting arm while on a road test
with the tunnel off (don't get caught up in the driveshaft because they
will probably have to put you into the coffin in pieces).
If there is no evidence of your "slipping " issue when the unit is manually
engaged then start looking into operating issues.
Haven't we been through this before?

So, here is Michael=E2=80=99s =E2=80=9CStep 1=E2=80=9D completed. (See =
his email, below).

1.	Removed the operating valve and, just for luck, disconnected the two =
wires into 3rd/4th switch. Took the car for a spin. Up/down =
longish/steepish hills, 10 miles on motorway. Various rpm=E2=80=A6..no =
slippage at all.
2.	Had a puncture=E2=80=A6..nail in tyre. Rear RHS. Flat as a pancake at =
once. Nearly onto rim. Nail! I imagine the inner tube is shredded and =
the tyre may be a write-off. (Usually are!). Anyhow, I bore you with =
this as I=E2=80=99m convinced that I=E2=80=99d never have got the wheel =
off without the little scissors jack which I carry to get the car up the =
first few inches until the Healey jack comes into play. Just a =
suggestion=E2=80=A6=E2=80=A6.
3.	Got home and jacked car up to test pressure. Steady at 520psi which, =
I recall, is plenty. Stayed at 520 across rev range. Dropped very slowly =
once engine was off and dropped to zero as I engaged/disengaged OD a few =
times. Which is normal I think?
4.	Solenoid makes a robust =E2=80=9Cclick=E2=80=9D when it should and =
engages the OD when activated.

So what=E2=80=99s a sensible =E2=80=9CStep 2=E2=80=9D??

I have been urged to check the setting of the Throttle Switch (TS). =
Assuming that the slippage returns (and why wouldn=E2=80=99t it?), =
I=E2=80=99ll short the TS out to see if that fixes it. If it does, =
I=E2=80=99ll check the adjustment.

Suggestions would be more than welcome=E2=80=A6=E2=80=A6I do dread =
having to take that box out again. I=E2=80=99ve got a very adequate ramp =
and a very strong volunteer(?) but, regardless of all that, it=E2=80=99s =
still quite a task. And, like a few of us, I=E2=80=99m not as young as I =
once was. I=E2=80=99ve always enjoyed the lines from the manual which I =
reproduce, below. =E2=80=9CGently ease=E2=80=9D!?!=20

            I have been urged to check the setting of the Throttle
            Switch (TS). Assuming that the slippage returns (and why
            wouldn’t it?), I’ll short the TS out to see if that fixes
            it. If it does, I’ll check the adjustment.<o:p></o:p></span></p>

Question  ... when you got home and did the pressure test I presume that
was AFTER you had put the valve with the "top hat", ball, spring and valve
rod cap and washer back into position?

Okay, then it is confirmed that neither the clutch (on the flywheel) nor
the overdrive cone clutch (in it's normal drive condition) are producing
the slippage.
>From this we can conclude that even when the overdrive solenoid is *not*
energized the slippage is occurring at the overdrive cone clutch and that
for some reason hydraulic pressure is finding its way into the overdrive
operating cylinders even when the overdrive operating valve is closed.
This can be caused by leakage past operating the valve or residual pressure=
.
The question of residual pressure can be resolved by checking that the
bleed hole in the bottom of the long overdrive valve push rod is not
blocked.
Whether or not hydraulic pressure is leaking past the operating valve ball
can be checked by ensuring that the ball is clearly on its seat when the
operating valve is *not * energized.

Could it be as simple as the rubber buffer below the solenoid plunger going
rotten and disappeared? This could also apply to adjustable metal stop on
the other model.

The solenoid will only work reliably if the plunger is well up into the
solenoid. If too low there is insufficient magnetic circuit to reliably
pull the plunger in.

I have had this where the overdrive does not always engage and sometimes
would disengage without a reason

Hi, Thanks for this.

Not sure I understand fully.=20

Once I=E2=80=99d finished the test drive with the OD operating valve out =
of the car, I returned the rod, ball, spring etc and put in the gauge =
rather than the nut. And got 500+ psi.=20

What I can=E2=80=99t do is understand the leap to the OD cone clutch. =
Not arguing=E2=80=A6just saying no comprende. As I sat in the car, I was =
thinking that the function of the OD seems OK and that it=E2=80=99s =
being interfered with by something in its =
circuitry=E2=80=A6=E2=80=A6relay, solenoid or throttle switch. =
That=E2=80=99s probably wishful thinking as I really don=E2=80=99t want =
to be swimming in those waters.

=20

I did, as a matter of course, clean out the tiny hole in the rod but =
didn=E2=80=99t detect any blockage=E2=80=A6.which doesn=E2=80=99t mean =
much as something minute could have been inside and been washed away by =
the detergent/hot water then WD40=E2=80=A6..

=20

After someone=E2=80=99s advice =E2=80=93 some time back =E2=80=93 =
I=E2=80=99ve got another rod whose aperture has been drilled out to =
1.5mm. This was =E2=80=9Cto allow the OD to disengage faster=E2=80=9D. =
Don=E2=80=99t recall if I tried it. Could that rod be any help here?

=20

The ball seems to be sitting square on its seat and the tip of the rod, =
where the ball sits, is not worn or chipped.

Residual pressure=E2=80=A6.. goes to 500+ when I switch OD ON and stays =
there until, engine and switch OFF, I energize the solenoid a few times =
whereupon it drops to zero.

=20

Another test drive(s) seems called for. But the hood is off to enable =
access and the forecast is grim for the next week.

=20

Very open to more suggestions. Thanks,

Simon

Okay, then it is confirmed that neither the clutch (on the flywheel) nor =
the overdrive cone clutch (in it's normal drive condition) are producing =
the slippage.=20

>From this we can conclude that even when the overdrive solenoid is not =
energized the slippage is occurring at the overdrive cone clutch and =
that for some reason hydraulic pressure is finding its way into the =
overdrive operating cylinders even when the overdrive operating valve is =
closed.

This can be caused by leakage past operating the valve or residual =
pressure.

The question of residual pressure can be resolved by checking that the =
bleed hole in the bottom of the long overdrive valve push rod is not =
blocked.

Whether or not hydraulic pressure is leaking past the operating valve =
ball can be checked by ensuring that the ball is clearly on its seat =
when the operating valve is not  energized.

"What I can=E2=80=99t do is understand the leap to the OD cone clutch?"

 Fair question.
Between the flywheel and the rear wheels there are only 2 places where
"slippage" can occur these are the clutch and the overdrive's cone clutch.
The gearbox, other than the cone clutch in the overdrive, is a go/no go
arrangement, i.e. no "slippage".
The rear wheel splines, believe it or not, can also produce "slippage " if
they are in really bad condition but I presume that isn't the case here.

The test that you just completed resulted in no driveline slippage when the
overdrive was disabled.
You are reporting slippage when the overdrive operating system is enabled
so it follows that further diagnosis of that is required.

Yes, your next step would be the same test drive, i.e. full engine torque
on an uphill grade, to confirm that the slippage issue has returned now
that the overdriveoperating valvehasbe re-installed.
I would do this test drive BEFORE making any adjustments to the overdrive
valve or solenoid in order to confirm that meerly installing the overdrive
operating valve resulted in the slippage issue returning.
Hope the weather improves, beautiful day here.

Spitballing ...

I went through my BJ8's O/D a few years ago. The car had 64K miles on it 
when I bought it (approx. 1984), and about 215K* miles on it when I did 
the overhaul. The O/D cone clutch was serviceable--and AFAIK didn't 
slip--and I reinstalled it. If new cone clutches were readily available 
I /might/ have bought new, on principle, depending on cost, but all I 
could find was a re-manned one from DWM. To me this implied they didn't 
often need replacement, whereas known wear items like the accumulator 
are offered by several vendors (I would have installed one with an 
O-ring if I'd known about it).

All this to say, unless the car has extremely high mileage and/or the 
O/D has been abused somehow I'd be surprised if the clutch is worn 'to 
the bone.' Obviously, slippage in the cone clutch would cause Simon's 
car's symptoms; if so, the problem will get progressively worse (and 
more consistent). I think one way to test an O/D clutch would be to 
really lug the car pulling an uphill grade in 4th-O/D, if the clutch is 
going to slip it would do it then (as would a worn engine clutch). 
There's also a (remote) possibility that, for some reason, O/D pressure 
fluctuates during driving.

* Anyone else have this many or more known miles on a Healey?

    depending on cost, but all I could find was a re-manned one from
    DWM. To me this implied they didn't often need replacement, whereas
    known wear items like the accumulator are offered by several vendors
    (I would have installed one with an O-ring if I'd known about it).<br>
    <br>
    All this to say, unless the car has extremely high mileage and/or
    the O/D has been abused somehow I'd be surprised if the clutch is
    worn 'to the bone.' Obviously, slippage in the cone clutch would
    cause Simon's car's symptoms; if so, the problem will get
    progressively worse (and more consistent). I think one way to test
    an O/D clutch would be to really lug the car pulling an uphill grade
    in 4th-O/D, if the clutch is going to slip it would do it then (as
    would a worn engine clutch). There's also a (remote) possibility
    that, for some reason, O/D pressure fluctuates during driving.<br>

    * Anyone else have this many or more known miles on a Healey?<br>
