Lately when driving my car if I come to a complete stop and put the shifter in neutral, it is then hard to get into 1st gear, or any gear. If I start to roll a little bit it will pop right into gear. I have the clutch all the way to the floor, and I have checked my master cylinder fluid and it is full. It almost seems like a hydraulic problem, but it is very weird b/c I have been driving my car for about a month and didn't have any problems until now. It is a newly rebuilt t56 w/ a new clutch, and resurfaced flywheel.

So could low transmission fluid cause a problem like this? I haven't had a chance to check yet b/c my jack is broken. Any ideas what it could be.

Perhaps you've got air in your hydraulics and it needs to be bled.

Or the slave or master cylinder needs to be replaced.

Check how much play is in the slave cylinder when you depress the clutch. I don't know how much movement is supposed to be in a T56 but I am guessing about 1-1.5 inches should be good (Does anybody know for sure?). Be a good time to bleed the system just in case, since you'll be down there.

If you have plenty of travel in the slave cylinder then I believe the clutch may be at fault, but seeing its been changed I am gonna put my money on the hydraulics as well.

Also check the fluid in the tranny while your down there, but I doubt it is a low fluid problem.

thanks for the reply, I will check all that out and try to bleed the cluth some more. I just thought it was odd that everything has been fine up until now. Also how do I check the play in the slave cylinder? Thanks again

To check the slave cylinder travel your gonna need someone to depress the clutch while your under the car and watching the travel.

Like I said I am not positive on how much travel its suppose to have but I am sure if you called a tranny shop they should know this off the top of their heads, but I believe 1-1.5 inches should be ample.

To bleed the system your gonna also need someone on the clutch while your releasing the bleeder on the slave.

Hope that helps, its been awhile since I did my T-5, but from what I understand the hyrdraulics are fairly similiar.

Okay the problem is that on the T56 slave, there is no bleeder screw. This is why so many people have problems w/ the hydraulics on these setups.

Also, I've been told that pressing the clutch in w/ the slave unbolted from the bell housing will cause it to explode, so how can I check the travel? I have read this more than once, any truth to it?

Thanks Again

Okay I forgot the T56 is not the same. Just realized the T56 has the slave going into the housing.

Sorry can't help then. I am sure someone on here must have an idea, or better yet try a fourth gen board, as they should have a much better idea on the T56.

I'm remembering one on the top of the slave cylinder just like on a T5 slave. `Course I've been wrong before, but a hydraulic system with NO bleeder makes NO sense.

As far as your problem, pressure bleed it with someone (pedal down, bleeder open, then closed, then pedal up) thoroughly and see how it ends up, clutch release-wise. Being that it's in all 6 gears, it's not the trans., it's the clutch release.

Thanks for all the help guys, but I am about 100% sure that there is no bleeder screw anywhere on the hydraulic system. I know that sounds crazy, but that is why soo many people have problems getting all of the air out of these systems. I have done many searches and researched the T56 hydraulics, and everyone says there is no bleeder and I have checked all over my setup and could not find one. I think I may have the problem solved though. It may take a little more time, but I'll let you guys know how it turns out. thanks again

Only way to get air outta a T56 hydraulics is to fork over the 120 bucks for a new setup..

theres a bleeder screw on the master cylinder isnt there?

Nope, not on a T56 but I think I'm getting it fingered out.

The T-56 master/slave is a complete and sealed unit. When it fails, you have to purchase a new one. There is NO way to bleed it, at least not to my knowledge and I've done several six-speed swaps including the one to my own car.

i wonder if my McLeod one had one or if I was imagining things

what happens if while installing the slave you let the pushrod all the way out on accident...is it trash?

Unscrew the reservoir cap. Take the slave out of the clutch housing. Dangle it at 45 degrees. Manually pump the pushrod. Air will bubble out at the reservoir. Continue pumping till all air is gone.

Black Beauty

the slave is held 45 degrees above or below the reservoir? below right?

yes it is held below, this is what I did and it worked. It CAN be bled of air, it just takes time and patience
