Will not go into gear PLEASE HELP!

[DSMjunkieNH]

Baught my buddies Eclipse GSX off him that had clutch issues. He was a smart kid and couldnt figure this out himself either. Ive had the tranny out 3 times in the past week and cannot figure this out. Everytime i finish up i bleed the clutch and adjust the pedal properly. Car will not go into any gear at all! heres whats in the transmission. ACT streetlite flywheel (had resurfaced because i thought that may have been it, machine shop says it isnt stepped at all), ACT street disk, ACT 2900 pressure plate, 1G slave and the car had an extremepsi master cylinder to slave cable. The previous owner told me that a performance shop out west had this problem with one of their GVR's because of the high pressured pressure plate they swapped the braided cable from slave to master and made their own hard brake line. I had the tranny out the first time and thought screw it this didnt work, ill make my own hard brake line. That didn't work either. I cannot seem to figure this problem out and heres where it gets weird. You can sit there and bleed it bleed it bleed it for hours and then itll go into gear fine and pump the clutch a few times and get it in gear and shifts like butter. let it sit overnight and it wont go back into gear. I really need help on this one guys im geting ready for IFO on October 13th and can use the help, im located in Rochester NH please post thoughts here of what you think the problem could be or even text me for faster responses. 603-767-8447

Sounds like the hydraulic system is either leaking internally, or air is getting into it. Try bleeding it again, see if it works again. If so then there is a leak somewhere, probably the master or slave cylinder needs replaced.

I agree with ^^^^ id look into the clutch master. Mine was randomly losing pressure, mainly if i didn't drive it or didn't have to shift for a while (not using the pedal on a long drive). Never saw a leak or lost fluid but I'm assuming the internal seals were shot. Made it tough to shift in any gear and sometimes grind downshifting with the pedal to the floor.

I'm sure having all the heavy duty clutch components only amplifies the problem, even if it were just a small loss of pressure at the pedal.

I agree with them, sounds like a bad master. I would also recommend checking step by yourself. It's not that difficult. I use Frequently Asked Questions for reference on adjustments. Hope that helps

Flywheel hasn't been stepped I had it resurfaced. I'm ganna change out the 1g slave for an oem 2g slave in a little bit . Don't think it's the master but idk we can't figure this problem out even had it to shops and all they do is bleed it for a while then it works just for that day.

 

[Breezio69]

So the only thing that's ever been done to the master is just bled?

I specifically remember when mine was going out, I could go out after sitting over night and the pedal was "limp". Meaning the first 80% of pushing it in was almost zero resistance, and it would barely return. Then I could pump the pedal about 8-10 times and feel the clutch pressure almost become normal, like and equal push throughout the shifting motion.

 

[Talyn]

Exactly how long does it take to bleed your system? You seem to be implying that it is taking much longer than it should(shouldn't take more than a few minutes with an assistant). Which could also be attributed to a leak.

 

[DSMjunkieNH]

It took us about 30 minutes to get all the air out. like i said before you can bleed it for a very long time, drive it and have to pump the clutch a little when you come to a stop, but once you let it sit and then come back to it, you can pump it up and still wont go into gear. It had the braided line from extremepsi on it and i removed that and made my own hard brake line. also have a 1G slave which is just a bandaid right now i honestly cannot figure it out at all!!

 

[Dave4g63]

I had a similar problem after I installed a new slave on my GST, turned out i messed up the little crush washer when installing it and didn't realize it. It wasn't really leaking fluid but she wouldn't hold pressure too long so I would triple check your lines and fittings. sure sounds like air is getting into the system.

 

[DSMjunkieNH]

Should i get a 2G oem slave and put the braided line back in then bleed it bleed it bleed it and see what happens guys?? that is crazy how just the washer did that to you man

 

[Dave4g63]

I would put new 2g oem slave back on it with a braided line and make sure everything is clean and that you replace all the washers. If all thats good then the only thing to blame would be the master cylinder. I would suggest bench bleeding the slave before you put it if you can, this video shows a pretty ingenious way of doing it [ame=http://www.youtube.com/watch?v=AWKybsZMHZs&list=PL4B97C16D423317DD&index=6]Trans & Clutch 6 - Bench Bleeding the Clutch - YouTube[/ame]

 

[DSMjunkieNH]

Jafromobile is the man! Thank you for that video ive been searching for one. My number is at the top of this post, saw your from NH and would love to meet new people man! Ganna give this a shot tomorrow or Friday and then let you guys know how it goes from there i doubt itll fix it though

 

[Breezio69]

i doubt itll fix it though

Why no faith? You said having the 1g in there was already a bandaid fix, and its the only component in the clutch system that you haven't replaced.

 

[DSMjunkieNH]

quick update for you guys, took my engine and trans out again for the third time. I am going with a completely different setup. Flywheel, disk, pressure plate and going from their. Eliminate the problems in the transmission that way if anything it is a hydraulic issue at the least. My Clutch setup that i had is for sale all for $350 shipped. ACT streetlite flywheel, brand new act clutch disk, and 2900 pressure plate.

 

[Skewer]

Sure sounds like a master cylinder to me! The op stated that bleeding it allowed it to work for a day. We have seen a number of cars come through our shop with master cylinders that have had internal leaks. The internal leaks allow air to get in to the hydraulic system... It was mentioned multiple times, but just go to the Mitsubishi dealer and buy an OEM master cylinder and call it a day.

We sell them too, if interested:

1G Master Cylinder

2G Master Cylinder

I've seen this problem on cars with too much fluid in the reservoir. The sudden spike of low pressure in the reservoir when you push down the clutch, combined with little or no airspace in the reservoir, causes air to suck in where the reservoir meets the master, and the fluid gets full of air bubbles. After a bunch of driving around, the clutch needs to be bled again.

 

[koafallenangel]

Definitely sounds like the Master but to be safe you should change both. If after changing them out and bleeding still doesnt fix them it maybe a small leak in the lines. Wipe them down and track back as far as you can to see if there is any drips afterwards.

 

[kenjiw]

This is what happened to me a few weeks ago. It wouldn't go into gear when the car was on and would grind if i tried to put it into reverse. What ended up happening was that a spring in the clutch fell out and lodged itself so it wasn't engaging properly. So i replaced the clutch and that fixed the problem.


EDIT: I actually replaced my clutch master cylinder first before replacing my clutch and i bled it properly and it still didn't work.

 

[Breezio69]

Man, sure sounds like you're doing things the hardest way possible and ignoring all the help in this thread.

But good luck with the new setup.

 

[mrichards56]

ok i was having the same problem do you have the stock clutch line still if so i would order a steel braided one i got mine from extreme psi because in the line is a pressure regulator/ resistor thing that sits on the transmission mine was messed up removed it and the line and replaced it and clutch works better then ever and its really easy to install.

 

[T-Flexx]

Had exact same issue on my first 91 gsx. My issue ending up being the master cylinder. Internal leak.

 

[YUPOK]

I'm going to throw my two cents in here,

I would have to agree it's the master. I had a master on another vehicle once that I could not get to bleed. It did exactly like your saying, would hold pressure for a little while then fail. I rebuilt the master with all new seals etc. Same thing. Turned out there was a groove in the cylinder that was allowing the pressurized fluid to slowly bypass the brand new seals and piston. No saving it, I had to replace the master.

Don't throw out your old clutch, upgrades are always a good thing but you should be able to sell your old clutch setup, this problem sound like hydraulic not mechanical but you'll have a nice new clutch setup from the experience.

Just think, when you finally get this fixed, you'll have fixed a nice car that nobody else could get right.

I Had the same problem as you and I fought with it for Hours! I bet you I bled that thing TEN times over, They way I got it to bleeed out was moving the slave (on the tranny) back and forth while someone else wasy bleeding and pumping the clutch, Finally after that it puked up a bunch of bubles and I could get it in and out of gear ....sounds like you have other plans though....if you keep having the sam problems try what I did I bet you it will work! good luck!
