Does this sounds like air in the line to you?

Car: S13 240sx 5 speed.

Today I had an interesting experience to say the least.

No matter what I did with the clutch, clutch in or clutch out, and what I did with the ignition, car on or off, (and all the variation of these 4 variables) I could not put it into gear.

Here's the story if you're interested

went to get my car tested for emission. So I drove around for a little while to warm up the cat and then I pull in. They do the first test and everything is fine. Then the guy leaves it in nuetral and wait to start the 2nd test. The car won't go into any gear. Not 1.

I'm thinking wtf is going on. They push my car out and it was true. It wouldn't go into any gear. WTF WTF WTF. I turn the car off and it won't go into any gear. Clutch in clutch out won't go into any gear. I turn it on thinking the movement will get the syncros meching. No luck.

After playing around with it for a little while it just pops in like nothing happens. So I begin to pull away and I stop on a red light. Put the car into nuetral and AGAIN won't go into ANY GEAR. I had to grind it into 2nd as traffic behind me gathered.

Also while it was in gear it slipped alot. But it wasn't like WOT where it goes grip grip gip. slip. It was more like it engaged during the last 5% of the throw and then would slip slip slip.

I was to scared for it to lock out of gear again so I help the clutch down at all the lights. When the clutch was 100% disengaged it would making a *SHHHHHHH* sound.


I have no idea what could of caused this problem but it wasted nearly 2 hours of my day off so I'd like to know.

doesnt sound like air in the lines, see if you are out of transmission fluid.

[SochBAT]

did you try repeated pumping of the clutch? Maybe you're short on fluids, or the clutch is crap, or the tranny is dry. IIRC, 80w90/

[ranisron]

tranny will soon be shot...

my Altima experienced the same thing (actually worse). my whole car would shake with the tranny...

75w90 actually cheat :p

or the slave cylinder is bad..
check to see if it moves out like it should.. and check the clutch fork/pivot ball too

frist check the fluid. then adjust the cluch peddle pivot.

I'm currently having a shitty problem with my clutch peddle assembly. The engaugement is all random. After driving it for 10mins, the engaugement would be at the very top of the peddle. It started at the middle. The peddle would be extremely hard to press too. I've checked the lines, zero air. This all happened after I rebuilt the clutch master cylinder. I thought i did something wrong to the CMC, but it looked fine after i took it apart. So now it has to be the slave cylinder that took a shit. I just got a new one from a member on here and about to install it in 10mins. Hopefully this resvolves my problem.

I also get locked out of gears sometimes. i have to like double pump to put it into gears.

strange thing: today i was at the school parking lot waiting for a spot. i must have sat there for like 10 mintues. Well once i found a spot. I let go of the clutch (foot of peddle so clutch is engauged) and the clutch wouldn't catch to the fly wheel. It seems like the engaugement went beyond on the peddle. I had to drive home like this in traffic; hoping i wouldn't get stuck in the number 1 lane.

stupid car!

edit: i just tested out the new slave cylinder. I'm still having the same problems. WTF?!
It can be my bent pushrod on my CMC or a bent clutch fork in my tranny :(

Here is something interesting I heard

"when they changed the clutch and didnt grease the input shaft. When it got hot, it would almost sieze onto the shaft, and she couldnt get it into any gears. If you let it sit a while to cool down, you could get it into gears."

Any comments?

[NemeGuero]

that fuckin' sucks if thats the case...
the first time I did my clutch though, I didn't lube the shaft... (hehe) and I didn't sieze..
that's really a poor design if that's the case. I think something else still must have been wrong...

makes a LOT of sense to me.

make sure you check the fluid though, I spun a bearing in a toyota transmission, it was pretty gnarly. all cuz I never checked the fluid, and it was doing things similar to your problem.

[KarateBoy]

By fluid do you guys mean the fluid in the lines or what's in my tranny?

I know my slave cylinder reservior is to the max, but that doesn't mean I don't have air in it.

Tranny fluid, I want to drop some Redline MT90 in there. Have any you guys ever hear of mixing it with something else? I believe some sentra guys do that...this idea seems strange to me.

[NemeGuero]

don't mix it..

[Slidin240Wayz]

Check the air.

it is best to change CMC and CSC at the same time. one being stronger than the other has a tendancy to blow the other one out, quickly. make sure to bleed your clutch to remove all chance of air being in the system

[nrg]

i have a rebuilt cmc, and new csc with ss lines. zero air in the lines; just checked it today.
I do have a bent push rod. so i really think this is causing my problem.
