Hey all,
I have a 2004 GTO with the 5.7 V8 6 speed with 45000 miles on it.This is my summer/fun car but not my daily driver. Every year I put it up for the winter. Since it has been getting pretty nice outside here in Ohio I decided to get my GTO out today. I finally got it all started and running. While playing with getting it running for the first time I did not have any issues with the clutch(It felt normal when pressing it in to start the car) Once I got the car started the clutch went straight to the floor. I pumped it a few times and still the same thing , no pressure at all. Since it has been sitting all winter I started looking for leaks and that kind of thing on the floor. No go. Everything thing looks good. I open up the clutch fluid reservoir and it is empty. I open the break one too and it is also empty(Not sure if this has anything to do with anything but just thought I would put it in here incase) I went ahead and filled both of them and then pumped the clutch a bunch of times( I know this is not the proper way to bleed the clutch but I watched a video that suggested it and I figured it couldn’t hurt) some fluid got taken in but not a lot. I have two real concerns. One where did the fluid go? Is this a common thing when cars sit over the winter? My car was barn stored but it doesn’t look like any animal damage or anything like that. All lines are metal and look good and are not leaking. The line that runs from reservoir to the cylinder was showing a very small leak but I was also moving things around a lot and im not sure if that’s how it normally is or if I hit it or something. Should I attempt to bleed out the clutch? or is that a waste of time? which brings me to my second concern, Two is that if there isn’t a leak that probably means its leaking at the slave does anyone know if my slave is inside or outside of the trans? From the research I have done I think its inside but not sure.
Any thoughts or advice would be awesome!

If you cannot locate the leak as is now, you will want to bleed the system. When you bleed it, there should be signs of a leak somewhere.
I have not dealt with the GTO at all, so I am not sure if your slave is on the inside or out (hopefully outside of the trans)..
Also is the brake fluid reservoir connected in any way to the clutch fluid reservoir? That would explain why both were empty…
JMHO

the first thing you have to do is top them off, now half the time if you pump the clutch a few times the system will bleed itself, however if it still isn’t engaging right, get a friend and bleed it, if your brake reservoir was empty as well they are either tied into each other or you have two separate issues you need to look for. either way you definitely need to bleed the brakes, they probably have a lot of air in them so bleed them pretty good, after all this is done clean everything really well with the cleaner of your choice and look for leaks.
Assuming your slave is in the transmission like on my Lancer, open the flywheel dust cover and see if your brake fluid is pooring out. if it is then your slave is bad and thats where your brake fluid is going.
On a side note if the above is the case, i was told with my car, that as soon as brake fluid gets on your clutch your gonna wanna replace it as it will damage it.
Best of luck to you in figuring out your gremlins friend!
Okay, I came home and started to bleed the clutch. I was then able to see that it is leaking where the transmission and the motor connected. So I am not exactly sure what this means but I know enough to know that it’s not good. I am thinking that it’s my slave but am not sure.
thoughts or advice would be great!Unfortunately, you have an internal slave cylinder… If you can’t find any leaks outside, then there is a very good chance it is leaking at or around the slave…
And if fluid got on your clutch, it is time for a new clutch (but if you are going to replace this, you might as well put a new clutch in anyway)

Ya that’s what I was thinking. How long do you think this job will take? I have done a good amount of car work in the past including a motor swap. I have not done a lot of work with the amount of time I work. This is my side car so I don’t mind it sitting for a while I work on it but im not sure if this is a job for me or not. I have never had to do a clutch before so im not sure what i am in for.
Advice on this?I have not personally done this vehicle, but being a RWD should be easier than a FWD… But you will have to drop the trans out of the way, so you have to raise up the vehicle safely some way…
Clutches, pressure plates and internal slave cylinders are real easy to replace, the problem is, getting to them… That is what takes the time..
I would guestimate a whole day if you are good with working with tools and have the stuff… Obviously a day or two longer if you lack tools and know how…
Here is a post I did replacing my Nephews Cobalt SS Clutch (and replaced the slave cylinder, which is the same type as yours). I am sure this is a lot more than you will have to do… But this can show you about how the slave works…
All the best
