Hello, I have been chasing a transmission gremlin in my 1989 9000 Turbo for more than a year now. I have paid to have the slave changed once, changed the master myself three times with one of them being rebuilt before I replaced it, changed the line from the reservoir to the master twice and commissioned a custom line from the master to slave. I’m running out of ideas.

There is no liquid leaking from the system, but air is still getting in. I have flushed the fluid more times than I can count at this point. I can’t bleed the clutch completely air-free.

How should I go about doing this? It’s stumped my usual mechanic, who is a foreign car specialist.

Clutch hyd setup Requires! a pressure bleed procedure.
There may be air in the system .. possible, as it's difficult to bleed properly
Two ways to do this;
a) a large /disposable 2 oz Syringe full of Fluid.. pressure forcing fluid into the slaves' bleeder nipple,, it's a Slow process tho.. persevere.
b) a rubber bung fitted to the Fluid reservoir opening and using a pump (bicycle even) to pressurize the Reservoir.

Other ugly factoid/possible is that the Slave which has a thin large O ring on it's back face.
On aftermarket units the machined in groove isn't as good as OEM at holding that ring in place.. as the slave is being manhandled during instal.
Unaware (inept?) mechs often unknowingly mount the slave with a displaced ring.
Which works for a while.. until it inevitably fails.
Then Blame is Loudly placed on the 'Crap quality' of the aftermarket slave.
Ain't Humans Grand?
