GR STI Squeaking Clutch, Pops out of 6th

Depends why it is popping out.

I'd assume not being fully engaged due to firewall issue.
In a different platform I might guess trans rebuild time.

That's what I'm hoping for. Trans only has about 70k miles.

popouts occur normally due to synchro wear...would suggest try fluid flush, if not its rebuild time...I too am not looking forward to the rebuild cost on these...get super mad at myself each time I mis-shift...

Yeah that's what I'm worried about. Hoping the quick fix will work (need to be installed anyways).

I don't believe it is normal to need a trans rebuild for a few times your cars milage. My 05 was over 230K when it was rebuilt, and it was still working fine. It was just making an clanking noise at idle when it was very hot. Shop told me they didn't see anything wrong with it! But since I have it's gear ratios lengthened while it was apart, it had all the important shafts and gears replaced. The noise was gone though we don't know exactly why.

I agree its definitely low mileage to have it happen...have seen it though when people rest their hand on the shifter while driving, grinding a lot an similar...im currently at 170k myself and have intermittent 3rd gear grind at high rpms fast shift, I assume the prior owner was doing some spirited stuff to account for this...otherwise no issues either

The car is single owner and I don't rest my hand on the shifter. I don't think I grind the gears or treat the transmission too aggressively but that sort of thing can be hard to self diagnose.

I think I'll have time to install the "firewall spot weld fix" this weekend. The issues with popping out of 6th only happens occasionally so it would be a while before I could confirm if it worked.

Try doing the humble rumble fix kit and also do a trans flush. See how it works out before going for the full rebuild.

Welp, pulled the cowl off and all the spot weld are in one piece and there's no noticeable flex in the firewall. I'll hold off on installing the kit since I don't see any reason to poke holes in my firewall and will hold on to the kit for the inevitable.

On another note, I noticed my clutch master Cylinder was filthy and when I opened it, it was very low. I'm now wondering if the squeaking is because air got in the system? I'll be putting the car on a lift in a few weeks to do some suspension work and I'm going to do the transmission fluid at that time as well. While I'm there, I'll bleed the clutch and take a closer look at the master cylinder assembly. The squeaking does sound like it's coming from that area.

Sometimes when the rod from the slave pushes the fork, there tends to be squeaking noise at times. What i do is spray it with some multi lube or white lithium grease all over it and the spring. It tends to go away after that and usually last awhile too. Not saying thats whats going on with your car but it may be something to consider.

I will have to give that a try. Thanks for the tip.

I also forgot to add this too. Ive done this as well and have had great success. This guys video is kind of funny at first but it works. For you case of describe clutch squeak, i would try my previous recommendation and also this one. Both are quick simple and cheap fixes. White lithium grease is our friend.

For years I thought my clutch was squeaking on my '12 hatch. Thought it was spot welds. Turns out it was actually the left side of my seat squeaking when I depressed the clutch.

You should do the Humble Rumble fix sooner rather than later, especially if you already have the kit. I did mine about a month ago with about 120K on the odo. There's no point in waiting. You'll be kicking yourself if one day those welds give out and you can't get the car into gear. It's really not that bad of a procedure if you take your time.
