transmission problem...wont go in gear

[smurf13]

ok...so today i was messing with my timing a little bit and i took it for a drive up the street. left the stop sign spun second a little bit, shifted into third and it wouldnt go in. came to a stop and it would go in any gear and the clutch pedal was stuck all the way to the floor...cut the car off then shifted through all the gears effortlessly. cut it back on and then it wouldnt go in again. cut it back off then it wouldnt go 1st but it went in every single other gear. so i put it in 2nd and drove it back to my house with a couple of weird whining noised. It didnt pop out of gear or anything but if i took it out of 2nd it wouldnt go back in to a gear. got in on my drive way and with it idling it went in every gear. took it up the street again it was very hard getting it into second and back into first when i came to a stop but it went in without grinding or popping out. parked it and 30 min. later took it out again and the bam...wouldnt go in gear and the clutch pedal was kinda stuck to the floor and then had to repeat the process

please help guys. thanks in advance...oh yea car is a 1992 240sx, stock dohc ka. im not quite sure if the clutch is after market bc the guy i bought it from didnt say anything about it but it does feel a little stiffer than a stock 240 clutch

first off I would check the fluid level...I had a similar problem last month...while you are under the car look at the slave cylinder, if its leaking that could be your problem...But what I really think the problem is, is that your throw out bearing is bad...only reasons are because you said you were driving hard enough to spin in first to second and that might have been the final straw. this happened to my buddies 240. He could only shft if the car was off and when it was running it had a crazy vibration...this is also the same problem that i encontered on my friends eclipse today...the bearing literely fell out in pieces...hope this helps

I have a feeling your clutch fluid is completely out. Pop your reservior and check if theres any fluid to begin with

[spooled240]

yeah sounds like the clutch is not disengaging at times. This happened to me not too long ago after I would drive my car hard, it was very hard to pop it in gear at a stop sign or wherever. For me, I just adjusted the clutch pedal out a little so there was more travel before it hit the floor, still had about an 1 inch-1.5inch of freeplay. It's pretty simple to adjust just make sure you have enough freeplay for the clutch wear...but of course check your fluids, master cylinder, slave cylinder, and maybe bleed your system for any possible air bubbles...

werd! check the fluids and if its full you might want to replace your slave cyclinder, sounds like what it is its not to expensive. though ill tell you this if your constantly on the clutch like hard driving burnouts drifting what not. you will go thru them fairly quick. i know i do least cuz of drifting

thanks for the inputs guys but yesterday the clutch fluid was close to minimum so i added some fluid before i parked it for the night and i came back this morning and it doenst seem to be leaking anywhere...will that pretty much eliminate the possibility of a bad slave or master cylinder? i can start the car in the gear i want but it will stall if i dont get it moving even with the clutch stuck to the floor

[Didderson]

it will stall if i dont get it moving even with the clutch stuck to the floor

if your clutch pedal actually 'sticks' to the floor or doesn't come up easily then your slave cylinder is probably blown. They're pretty cheap to get, should be below 20 bucks at autozone. It could also be that pivot ball on the clutch fork is broken but your problem seems to be from elsewhere. Only way to truly find out is to pull the trans off, or fix the slave cyl. bleed it and see if that fixes things.

Good luck

Go and check your slave cyl. There may not be any leaks on your driveway, but push the boot around with your fingers and ill bet you fluid comes out. First have a friend push your clutch pedal in and get down and watch the salve cyl while he is doing it. Does it move? No? Then replace slave cyl, remove damper box if it is still there, and bleed it. Yes? Does it have full throw in it? Yes? My bet would be on broken clutch fork pivot.

[spooled240]

bleed your system man, it's easy just need two ppl..get your gf or wife w/e to pump the clutch pedal while you undo the bleeder screws near the slave cylinder and on the pass side frame rail under the car....if your lucky, the bubbles will spurt out and your clutch will be fine..

[smurf13]

i checked my slave cylinder the other day and it seems to be doing what its supposed to be doing, its moving when the clutch is pressed down. it isnt leaking anywhere and we also tried to bleed it. im kinda leaning toward the the throw out bearing because its making a weird whining noise when i press the clutch all the way down. if not that the clutch fork pivot but either way im probably going to have to drop the transmission.

[spooled240]

is it a loud noise? I never heard of a throwout bearing screwing up and causing the clutch to not disengage/pedal to stick to the floor...

the clutch pedal linkage does have a mechanism where the pedal will stick to the floor as you may have noticed when bleeding your system..

did you try adjusting your pedal? I was thinking maybe the pedal doesn't have enough travel to the floor to disengage the clutch all the way. Try it man it's simple-look at your clutch linkage under the dash and loosen the nut and you can spin the rod that goes to you master cylinder which will adjust your clutch pedal..try this for troubleshooting because dropping the transmission is a bisch good luck!

[smurf13]

tried to adjust the clutch pedal but no affect, still wont go in gear when car is on i would i check the clutch pivot fork? is the only way to drop the transmission?

[spooled240]

i don't see any other way

[1sikS13]

dropping the transmission is really quite easy, you should not stress to much about it, besides if you have never done it..its a good experience. i can drop min in about 15 minutes now and 5 minutes of that is just getting the last bolt on the top of the transmission which is a ****in pain in the ***

[Vegascorbin]

One note of caution about droping a trany if you have never done it. The job is not hard but the Trany is heaver that people think. DO NOT BE UNDER IT WHEN YOU WORK IT LOSE OF THE ENGINE. Use a jack and wood blocks etc to support the transmission while removeing it.

Droping a trany on yourself HURTS! (don't ask how I know this:)

If you have the parts ( clutch, pressure plate, throwout berring etc) you can remove the transmission, replace the clutch (speaking stock clutch) and reinstall the transmission in an afternoon if you are at all handy with tools and have a friend to help handle the transmission.

thanks for all the tips guys

so what happened on this?.. im having same problem now on my 92... on new stage 4 clutch and jun flywheel and i also changed the fork to what i thought was a newer one... im thinking its my throw out because of the whining noise it made when i pushed clutch in for the last week it shifted

[g35paul]

well i fixed mine the other day... my throw out bearing went through my pressure plate... I guess i had way to much pressure on it... the pedal was adjusted all the way out... seems to be fine now that i replaced clutch, pressure plate, throw out and adjusted clutch.... i
