Hey guys, kinda having an issue with the car... About a year ago, I noticed during a 3-4 shift at wot, and high rpm, my clutch pedal gets real stiff and makes it very difficult to make the gear change. Now this doesn't happen all the time, seems to come and go. I'll give you some info:
- 66k miles on the car
- Rev limiter set at 7750 rpm, I shift around 7600 rpm give or take
- Clutch does not slip
- No issues during normal driving or 1-2 wot shifts
- Fresh clutch/brake fluid and properly bled
I've been researching the issues for a while now, and still can't come to a final verdict. Give me some thoughts and opinions on what this might be.

The thread below is the best thread describing my issue, but never explains the exact cause:
I had this issue on my LNF. I have no idea what that thing is, but removing it fixed the issue. I feel like its some type of buffer to make the clutch pedal easier to push.

The only other thing I can tell you from my LSJ days is the TOB pressure valve starting to fail. There is a valve in the TOB that bleeds of excess pressure in the high rpms. When it fails it gets difficult to shift and sometimes can lock you out. This is one of the biggest reasons the LNF is considered an upgrade as it does not have this feature.
Here is mine when it failed on my LSJ. First the pedal started getting hard. Then is became almost non-existent. It never leaked a drop of fluid and when I pulled the trans all of that fell out. Drove it home 1000 miles broken like this.

Yeah, this is in the back of my mind as the issue (hoping its not), lol.
It's odd that it wouldn't act up all the time though and every gear if this was the case.
Its probably starting to fail. It seems to slowly fail. Maybe it has something to do with load/torque? Idk for sure. Having changed over a dozen TOBs on these cars I have never understood them, I just hate them haha.

Yeah, I always hear of people having issues with tobs during clutch installs and such.
They are super fragile when empty and being filled. Too many people try to bleed them like brakes and **** the seal on them. Vacuum bleed them only. Do not bench bleed. Inspect the seal prior to install.
The round thing on the line is a damper. I deleted mine and it is night and day better. I was told they only came on base models, but idk how true that it

I had one in my LNF.
Its abou 4" in diameter circle right off of the master cylinder.
Thats what happened with my clutch it felt like very hard to press the pedal at high rpm shift from 3-4, lots of load. I was told it was the pressure plate shitting the bed.

My pressure plate and disc were fine. Could have put them right back in.
Did some google image digging but couldn't find an actual picture. It has the standard line male and female fitting on it. Male line into female side of the damper, and then the male side of the damper into the female clutch master. If you pull it out, the male line fits into the female clutch master.
Not sure if it will reach with the factory molded line. I know it reaches with an aftermarket braided.
There is a good chance you don't have it, but if you do I would remove it regardless if it solves the issue or not

Thank you for this. Now I know what to really look for. I took a quick look yesterday, but I was in no mood to be under the car due to how hot out it was. I'll check again today as I'm replacing my trans fluid.

Don't know if it was so much the clutch you needed or the new TOB (which I fear is my issue)... but you also mention your flywheel was shot, so I see how that helped. My clutch seems to be perfect still.
I did a solid pull this morning pulling onto the highway, and shifted into 4th and had no issues. Seems like it happens more on hot days.
The dampener is seen from the top. Look behind the fuse box next to the strut tower. You move have to push a wire harness to the side but you can see it if it's there. You can see where the line connects to the master and it's right off of the master of you have it.
If you have it hit up Josh and get the OTTP stainless steel clutch line. I have it. You can't just remove it as you will need a longer line to reach without it. Josh's line is long enough to use it or delete it.
