Bleeding T56 Clutch??

[vette427-sbc]

LS1 T56 with a GMPP Hydraulic throwout bearing, remote bleeder... How the hell do you bleed these things??!! has anyone had any success without using a vacuum bleeder? Im getting a little pedal by doing a conventional push clutch, open bleeder, close bleeder, release clutch. But the trans still grinds going into gear. Its odd, it will go into gear once or twice, but then the pedal gets worse and it will grind horribly. I dont see any leaks or drips anywhere. Going to try some more gravity bleeding tomorrow.
Reason for emergency: Big fathers day car show that my dad and I always go to together. I would like to at least make an appearance with my car.

Sounds like you might have a leak or a bad clutch. Those are much easier to bleed then the lt1 t56 that I'm familiar with. You should be able to gravity bleed as well as bleed them like you would brakes. I could be wrong, but in theory it seems like the same concept as brake bleeding.

Whats your clutch pedal ratio? Is it pushing enough? Is your throw out bearing shimmed enough?

When I first bled the system, I put the trans in gear, had someone step on the clutch and I was able to rotate the driveshaft by hand (indicating it was disengaging). The more I think about it the more I think its an internal leak somewhere. Thanks guys

Is your master cylinder "bench bled" properly? The reservoir on the clutch is usually so small it is easy to run it dry when bleeding the t/b.

You have to hold the bleeder above the throw out bearing to get the air up to the bleeder. I used a Mightyvac last time to do my clutch with great success.

buddy of mine had this issue....he counted and said he said he had to pump the pedal 64 times before he actually got some sort of resistance to bleed out... then he pumped an additional 50 times... bled out... 40.. bled... and so on... until the pedal felt stiff enough

Only thing i got to work reAlly good was a phoenix pump- push the fluid in from the bottom up & the air rises... Tried everything else & this was the best for me After days of working it.

I cant bench bleed the master since the reservoir is attached to the car, so I let the master hang vertical to let the air from the back float up. Seemed to work as I was able to take the car out tonight for a drive. The pedal is really light though. Im not sure if I like it to be honest. But it seems to work so Im happy. Clutch is just a centerforce dual friction.

This is a good tip... I think Ill try this to see if I can get anymore air out of the system. Thanks!

I like this too...

The mighty vac is 20$ and is money, I just changed my clutch master over the weekend and it took me 10min by myself to bleed the new hydraulics with the hand pump.

On my set up, I had to pull up on the clutch pedal to kinda get fluid moving then I was able to bleed normal.

You are probably done by now but I also tried and tried and what worked very quickly for me was to use my mighty vac with the cone end on it. I had my son push down on the pedal and I stuck this in the internal hole on the master cylinder and pulled out any air that way. it has worked ever since.
