Help please-no clutch fluid is coming out

obender66

Hi all,

Clutch fluid is getting very dark so I thought I'd flush it out. Done that dozen times on G35-no issues.

After pumping clutch pedal and holding it in I opened bleed screw and few drops of fluid came out. That's it. Pumping clutch pedal more did not help. I pretty much unscrewed bleed valve completely-nothing.

Otherwise clutch works fine-feels like brand new, gears shift fine, pedal does not get stuck on the floor. That means that there's a proper pressure in the system.

I emptied reservoir, wiped all sludge and filled it with fresh RBF600, but I want to have all the crap out of the system!

Help with this will be greatly appreciated!

Alex

All that immediately comes to mind is you have so much nasty in there that it's clogged the bleed screw.

THIS.

Can try removing the bleed screw entirely.

I replaced about 1/2 the bleed screws on my calipers over the years.

If you took it to a dealership they'd tell you you need a new transmission.

At least remove the bleed screw completely and see if it starts draining. If it doesn't, there is a union for the hardlines in the driver side wheel well behind the fender liner that I would check next.

You may not have to remove the bleeder. Open the valve and stick a small, stiff wire in the hole. Doesn't work all the time but a lot less messy than removing the valve.

Update:
Took the bleeder out-nothing. Just stuck a pin in hole where bleeder came out and all the goo started to drip-dark gray, almost black, gradually getting cleaner. I let it gravity bleed for about 5 minutes, then I screwed back the bleeder and hooked up Mityvac vacuum pump(8500 model) and let it drain overflow tank about 3 times. No, it does not have enough pressure to damage the seals, but does great job evacuating the old fluid out. I do not think that fittings can properly seal the system to get the air out, if any-that was not my issue.
Tightened bleeder up, started the car-all gears worked fine. So Mityvac as one person fluid replacement device works.
For a little piece of mind I did clutch pump routine couple of times-all clean liquid coming out, all gears work fine.

Thank you all for help

Alex
