Help, gears won't go in all of a sudden

[jworks]

So the gears for my 92 hatch will not go in at all, every time I try to put it into a gear it would either dully bounce off or make a awful grinding noise. It was working fine all day yesterday no problems what so ever. Does anyone know whats going on here?

slave cylinder

slave cylinder

Is it known to just go out like that?

[bbejj123]

things can happen...after all it is a 16 year old car

[jworks]

Can it be the master cylinder? I just got a call from someone saying it can be the master cylinder.

[SW20Racer]

can you engage the gear when the car isnt running? i was able to when i had the same problem, and it turned out my clutch explosioned all up in my tranny from being old. it was even kind enough to cut 1/4" gouges into the transmission walls

[sil40drift]

It can be both.

Get under your dash, Look for leaking where your clutch pedal goes through the firewall. If there is fluid, your master cylinder is bad..

to check the slave cylinder you can get ur ass under the car and have someone push the clutch pedal and u watch and see if the slave cylinder is pushing the clutch fork. also look for leaking fluid by the slave cylinder. check for leaks period.

Both slave and master cylinder are an easy job you simply unscrew the lines, Unbolt and bolt in the new one then run some fluid through it and bleed it. Simple.

I just check under the car, there are no fluids leaking

[fran13]

that doesnt matter it could've been leaking all this time while u drive and u couldnt notice oh and how are those shock u picked up from me.?

[fran13]

trust me ive gone through both of those problems like 3 times on the slave cylinder and master clutch they both mess with ur gears. oh yeah both can happen from one day to another.

dosent matter. check anyway. mine was shot as well. it wasnt leaking, but when i took it off it fell apart. basically just go ahead and check everything.

[ericcastro]

check to see if your clutch fluid is full.

Then go under your car and have someone push the clutch while you are looking at the slave cylinder. does it function??

clutch fluid is average, where exactly is the slave cylinder? is it obvious to see when I get under there?

[ericcastro]

yeah, it is on the side of the trannsmission. It has a little button that pops out when the clutch is pushed. this little "button" looking thing is what engages the clutch parts that are inside your transmission.

If the little "button" isnt poping out and pushing the end of the fork, then you cant disengage the clutch to change gears. And there is a problem in the line somewere.

Trace the line going from the master cylinder to the slave. You'll see it, its on the right side of the tranny.

At the end of clutch line.

[astrophixvox]

My gears didn't start grinding over night but I replaced the slave cylinder and the grinding noises stopped. Process of elimination.

[jworks]

The slave cylinder is working and there are no leaks, so I'm assuming that its the master, so should I go ahead and replace both slave and master?

[mrmephistopheles]

Damn this is so dumb

COULD BE MASTER, SLAVE, OR CLUTCH!

Do this:



1. Check hydraulic clutch system.

Look under the car while your boyfriend pumps the clutch. If the little rod pushes the armature back ok, then your hydraulic system is fine.

If fluid is leaking when the clutch is pushed, check for the source, and you'll figure out which cylinder is bad. For the slave, you may have to pull the boot back to see if it's leaking.

If it's the clutch, you may have thrown a spring (I had this happen once).

2. Check Clutch!

This is basically a clutch job, so if you only have one car, have a spare clutch ready to go.
You may have shattered your disk, thrown a spring, or any number of random occurrences. Any of these can cause you to lose the ability to change into gear (while the car is on).
Just take off that old clutch and inspect it. You can put the new one on or try & reuse the old one if everything seems ok, but if you're going to put on a new one, you must resurface the flywheel.

Could also be the clutch pedal bracket itself snapping off.

[ericcastro]

The slave cylinder is working and there are no leaks, so I'm assuming that its the master, so should I go ahead and replace both slave and master?

If the slave is working, that means its the clutch itself. The slave wouldn't work if the master cylinder didn't work.

So we already figured out the problem before the MOD came in.

So follow the second part of his advice. your gonna learn to do a clutch job. its actually pretty easny. A one day deal. Couple hours if your quik. just make sure to have a friend help or be careful when pulling the tranny off. Its heavy and can fall on you. Also make sure to use some jack stands so the car doesn't fall on ya.

good luck.

post your findings when done.

[Kwonza Says]

My flywheel bolt broke off and I couldnt put it in gear so yeah clutch job look for that and if it did break off then buy all new bolts good luck : )

[soreballz]

I'll add to the list of things it could be... CLUTCH FORK PIVOT.

Does the pedal feel normal, or stiffer than normal? That'd be a broken clutch disk.

Pedal won't come up? Either the slave, or the master cylinder.

I'm not sure what a broken clutch fork pivot feels like.
