Its common to have issues bleeding the clutch. It may still have air in the lines. If this is the case, you need to unbolt the master from the firewall and set in on its side or upside down. This lets the trapped air escape. I did with 2 people, 1 pushing the plunger on the master up and down as if pumping the pedal, he was also gently tapping it to free any air. The other person does the typical bleeding procedure opening and closing the nipple. Good luck.

I had a mechanic friend from BMW stop by and we got it working, but then after a few more attempts it gradually stops working, so we figure there is a air leak and we pinpointed it to the master, cuz there is a newer slave from the wrecker yard. Il try that and see if it works, thanks for all the help guys il check back in if that doesnt work.

Ok, so i replaced the master cylinder as the clutch would not hold for more than 1 min without being unable to shift again. Now I when i am idle its fine and I can switch gears ok, but when i start driving as I drive the pedal becomes squishier and squishier until it start having problems again. If I pull over and give a few pumps the pedal comes back to life and works fine. WTH? Any suggestions? Ive replaced everything but hose and slave, but slave was from the tranny at wrecker yard. I dont think there was a hose attached to it though, so that may cause a problem.

Just buy a new slave cylinder. Your probably wishing you did that to begin with because now the tranny has to come out again.

The weird thing is after i turn off the truck, and pump the pedal it comes back again, and start working, its just once it starts driving that this happens.... seems really strange.
