What's up. I'm no mechanic, but I've had these issues before. I would say that your problem is in the hydrolics. I would check the hydrolic fluid resevior to see if it's low and the condition of the fluid. A nice fluid swap and bleed would be a good start. I would wrap the hydrolic line with some heat resistant tape to prevent your headers from cooking the fluid. That was what cured my "spongy" pedal after I would beat on the car or just rev the engine like a mad man. If your fluid is low, I would check under the bellhousing and around the master cylinder (in and out of the car) for leaks. But if your low on fluid, I would say there is a problem other than air in the line or cooking the fluid. Good luck.

 

Most have good luck by simply replacing the fluid - try that first.

 

You can try to bleed it but that usually dosent work....at least not the 4 I've seen. If it fails to work you MOST replace the slave cylinder and master cylinder at the SAME time. The reason for that is because you dont know witch one is causing the problem. In my case I started at the slave and it worked right for a week then started again. The master cylinder failed at that point. My buddy started at the slave as well and it was not the problem it was his master also. Since the problem was the master there was debree in his lines that did not come out when we flushed becase it was stuck in there, that ended up inside his new slave cylinder and needed to do it all over again. So thats why its a MUST to do at the same time. Good luck I hope this helps. Check the stickeys for more info.

 

I had this happen to me recently, turns out when I bled it at the beginning of the season, some air got stuck in the system. At the time, 2 things worked against me here, first was accidental pump of the clutch with the bleeder open. Second was the reservoir going empty.

Thought I had all the air out after bleeding it for half an hour, car drove ok, tracked fine through the 1-4 gears under WOT. It wasn't till a month later when I tried a highway pull in 3rd and 4th that the pedal "stuck" to the floor. Tried another bleed, fluid was clean. Had no clue what was going on. During dyno tuning, kept sticking. Was ready to go get a new slave, but figured before I do that I'll buy a mityvac and try it out. First time out, grabbed a good amount of air from the system. After numerous sessions with the mity, it finally is normal again. I'd try a normal bleed first followed by a mityvac.

 

Well I have checked my fluid plenty of times and replaced it with DOT 4 fluid...it seems to kinda sorta help the pedal return but doesnt completely.....but im defintley gonna try the mityvac...i was reading on here about drill mod thingy..thought bout tryin it after the mityvac....do u all kno any good ideas on a new transmission? or ideas on a rebuild??...but thanxs for the help, greatly appreciated ill keep u all posted on what happens

 

You dont need to rebuild your trans look at my post above.

 

im pretty sure im gonna be needin a new transmission its grinding in 3rd and 4th...it will go into gear if you are easy with it...i think the synconizers are going out...any ideas?
