Clutch pedal sticks at redline

My clutch pedal does not come up when I shift at redline. It comes up a few inches and then I have to lift it with my foot. Only happens at close to redline. Anyone have this issue?

Very common issue on this trans. Look into removing the "assist spring" on the clutch pedal. If that doesnt help, look into swapping to a stainless steel clutch line and adding some DOT4 brake / clutch fluid.

Is taking out the assist spring an easy fix?

Takes 10 minutes. Search them on google, theres quite a few videos and write ups. You will notice an increase in pedal effort, but its not going to be anything serious.

Do you think this could damage the clutch? Basically slipping the clutch?

Removing the assist spring? No, its just there to reduce pedal effort.

The sticking? Possibly, but basically as soon as you let out the revs will start dropping, and the clutch will return to normal operation (and under virtually no load at that). Its not anything like slipping the clutch for a 1/4 launch. Interesting point though, i've never thought of it like that before, but i dont think its an issue in that sense.

I believe Ish had the same issue with his car a while back.

Ya i meant the sticking. I just don't want extra wear on my clutch. Haha I can already do that myself. I will just pop the spring out tonight. Thanks for input!

Still do. Removing the clutch assist spring made my issue much worse.

I posted a video of this on youtube after several trips to local dealers and being told it's "normal". Someone from Ford sent me a message on youtube asking me to remove the video. Shortly after, my dealer had gave my information to Ford corporate for them to contact me. I talked with an engineer and he said that they were well aware of the issue and were working on a fix for all MT82 equipped cars (Boss, GT, V6) along with the new design being implemented into the S550 and that it would be available as part of a service bulletin. That "fix" was supposed to be out in early spring of this year (2014). To my knowledge the "fix" never happened.

My thread about this along with a link to the video I posted - Clutch pedal sticking..

If I knew I was going to keep my car for more than a few years, I would just Tremec swap it. However, I don't see myself holding onto this car for much longer (likely let it go sometime next year), so I will just deal with it for now.

Ahh yes, i remember us talking about it now ... I still think your case is different than everyone else, removing an item restricting the clutches ability to return to neutral physically cant make it worse... You obviously still seem to have the issue though, so maybe its something more extreme. At any rate, that conversation has already taken place, no need to have it again.

On a side note - mine has gotten better after a fluid change. 1-2 still does it frequently, just not as often, 2-3 hardly ever has an issue anymore.

I never noticed it before. Until I started doing 3rd gear pulls for data logging. I know I don't have the problem in 1st or 2nd. Not sure why it happens in different gears for different people. I would expect it to happen in all gears or one specific gear for everyone.

Well got the spring out. Now I just need to wait till it gets a little later to test and see if it did the trick.
