Hi, my Dad has a very well cared for 2001 Mazda B3000 5sp manual tranny 2wd truck (same truck as a Ford Ranger). The transmission started making a noise a few weeks ago. We drained the fluid and put in fresh, did not solve the problem. The tranny and clutch worked fine just made a horrible noise every now and then. We knew it needed a new clutch, pressure plate, and throw out bearing. We had already priced the parts. My Dad has been working 6-7 days a week. We were just waiting for him to get a weekend off to tackle the problem.
Someone told him at work that before tearing into the tranny try and bleed the clutch and see if it helped. Well a couple of days ago my Dad just opened the valve on the slave cylinder and pumped the clutch a few times to try and bleed it. Since then he has no clutch watsoever. There is no clutch pressure. We have pumped and bled, pumped and bled. I have searched the internet over to try and find out what we could be doing wrong. Tried all of the remedies found on the net. But still no clutch.
Is there anything we are doing wrong? Or is there any tricks or procedures we could try? This is his only way to work. All he did was release the slave cylinder bleeder on the tranny. No new parts or nothing. He had perfect clutch pedal before he did this. We are so baffled. Any advice would be greatly appreciated.
Thanks,
brc

Hi there !
It depends on the noise you hear and when you hear it because if its there all the time that mean its inside the trans but if you hear it just while you push the pedal or when you need to shift that means your clutch cylinder or pressure plat or throw out bearing has issues. So maybe you need to discribe more about the noise and when it starts .
Also I think there is air inside the oil line, maybe when you or your dad was pumping the pedal to bleed the cylinder there was air coming back. so try to do it again.
let him pump the pedal while your hand on the cylinder plug and after he pumps for 5 or 6 time tell him to push the pedal all the way down and hold it , then open the plug and let the air come out then close the plug and tell him to pump again and do the same operation until he feels more pressure on the pedal and dont forget to add fluid before it runs out . if it still bad maybe you will need to rebuild the clutch cylinder or buy new one.
Good luck buddy

Thanks so much for the reply. We are not really concerned about the noise at this point. It is not much of an issue. The problem that we can't solve is getting the clutch back working. We have done the procedure you mentioned about pumping the clutch and opening the valve and filling the resevior to get the air out. We have pumped and bled so much this weekend that we would have take turns b/c our legs would give out. We went through three full bottles of brake fluid in the process.
We just don't know what to do.
Thanks again,
brc

Well my friend i think you got a check teh salve and master cylinder because if the seals inside are worn out that means they dont hold pressure, So you can just change it or rebuild it .
The same thing happend to me 5 years ago and drove me crazy i was pumping for hours and the pedal still the same thing untill i changed the master cylinder and everything went well.
Good luck buddy

brc19761; I agree. Sounds like a hydraulic problem... Just like a brake master cylinder, if you are 'foot' bleeding, it is very easy to go past the normal pedal travel and rupture the cup in the cylinder. Clutch master cylinders and slave cylinders should always be replaced as a set. If money is tight, I'd go with the master, first.
Check up under the dash, where the pushrod comes out through the firewall. Pull back the rubber boot and see if any moisture is present. If so, no-brainer. Replace the master cylinder. I prefer to gravity bleed hydraulic systems, but doesn't always work. But, with a new master, you should be able to 'foot' bleed without any further issues.
