woke up this mourning, and my car wont go into gear , when the engine running it cant get it in gear, the clutch has preasure, its a new slave and master cyclder and i think the slave's seal is cracked, but i know dont if that would make it not able to go into gear. gosh i hope its not a tranny problem.

Yes you need to replace the slave if its cracked

twigg

yea the slave is fine its the seal between it and where its connected, leaks from there, but i knew that and it still went into gear, not it wont at all. so that should fix it?

A cracked seal in the slave cylinder will not cause this. If the pedal feels good, as in doesn't go down to the floor real easy, the problem is likely elsewhere. I can't really say what it could be, but first place to check would be the clutch disk itself.

twigg

anyone else have any ideas what it could be? throw out bearing? hope i didnt just foobar my clutch

i had this happen to me once ... with me it was the pilot bearing broke and all the little needels packed them selfs against the clutch and pressrue plate cazing it to keep from engauging also i know of a honda that the stock clutch came apart at the rubber as it doesint have springs on the clutch. some of the rubber broke and packed it self inbetween the same way...and the stock rx7 clutchs have rubber also so this could have happend.....more likey than anything something is jamming the clutch to keep it engauged when the motor is on.

you can get under the car and take off the starter and see if you can find any chucks of rubber, clutch or needel barings in the bottom of the bellhousing. any thing more than dust in there you may have found your problem

good luck

simple question, but maybe it was over looked. Did you check your clutch fluid?

Also, how well did you bleed it, they can be a bear to bleed properly.

Could be a pilot bearing.

i just got an 85 gsl-se and and having a similiar issue, sometimes it engages properly and sometimes it doesn't, could it be one of the same issues?

Thank you for using the search function, first of all.

You say it only happens sometimes? Under what conditions does this happen? It could be a problem with the hydraulic system if it only happens under high rpms, when first starting up, etc. Does it get better if you "pump" the pedal?

If the hydraulics are OK, it's prolly the transmission itself. The FB transmissions don't seem to be very strong.

have a friend step on the clutch while you are looking at the slave to see how far the fork travels and see if it holds its' position. the new brake master and clutch master you just put in may have been sitting around on the shelf for a long time from where you bought it. Could have issues. Bleed the system again, check fluids, and check to see how the fork travels. you can eliminate the hydraulic part this way. If it'a all good then you have other issues as mentioned above. pilot bearing, pressure plate.....

I'm having a similar problem. I had the problem last winter and now it's back. For some reason, when it gets cold, the clutch pedal doesn't seem to be doing it's job. The fluid is new, it's been bled and there are no leaks, so it's a mystery to me. Try warming up the car for 10 minutes and see if the problem goes away. If it does, then maybe someone can figure out why.

drp

when i start her up it seems pretty good still a little rough, but it does once it is gong already. it started last week on a cold night and does it since then. it happened just now, i was driving slower than usual ( even less pressure on the gad pedal so it took me longer to shift) and shifting between 3300 and 4000 rpm. once i turned the street the gears wouldn't go in anymore. i pulled over and sat there for a few seconds pumped the clutch waited a few more seconds tried once (no luck) then it went into gear the 2nd time. the car has 72k original miles so i dont think its the tranny. i am new to the whole rx7 but where would i check the oil in a 13b engine?

this time it only happened once, last time i drove it (wendesday) it happened like 3 times....

I would say to cross your fingers and hope it's just a hydraulic issue. You figure after so many years, you're probably due for a replacement master and slave cylinder anyways so that's where I'd start. If that doesn't fix it, then find a used tranny to throw in there. They seem to be a dime a dozen lately. In fact, I've got a spare in my own garage at the moment.

is there a way to check the tranny fluid? also i was going over receipts and such and it looks like the previous owner rebuilt the slave cylinder like a year ago. if its is the master cylinder (crosses fingers) would it be better to rebuild or get a new one?

I should mention that he had replaced the brake fluid with dot 4 with silicon i believe and it was a bit low so i added dot 4 (not sure if it had the silicon) would that maybe be the culprit and all i need is to bleed it?

Thanks for all the help...

Even a new master or slave cylinder will be faulty. I ran into that problem when I replaced my setup from Advance Auto Parts. Ended up going to my import parts supplier instead for a new master and slave.

I prefer to buy brand new instead of a rebuilt kit, just for the fact of having a new item, brand new in the box, ready to be slapped on. Less complications. And, I didn't think they offer rebuild kits on master and slave cylinders.

Tranny fluid is checked by crawling under the car, removing the fill plug, and putting your finger in there. The fluid level should be right at the edge of the hole. If it's lower than that, fill 'er up.

drp

if its worst case scenario and i need a new tranny, how much does one run, can i swap it for a 2nd gen tranny or do i have to stay with my tranny type?

Don't jump the gun yet. Check the hydraulics and make sure they're working properly, if not, replace both the master and slave, along with the hose. If those are good, then check to see if the pressure playe is releasing. There are 2 inspection covers, one on the top, the other on the passenger side.

If the pp isn't moving, it could be a bent/cracked clutch fork or the pivot ball that it mounts on has snapped off. By now it's time to pull the tranny and inspect those parts along with the clutch, throw out bearing and pilot bearing.

drp

i will have to have that checked out, i dont know much about clutches or trannies. I have been double clutching aswell, will that help at all?

last question of the night, its concerning me that when i stick the car in reverse its always makes a thump sound and it seems to be forced to go into the gear, is that due to old age or ????

It happens mainly when the car has been running, and not really from a cold start.

85 FB

A thump noise? When you put it in Reverse, do you first put it into another gear, like 1st, to keep the transmission from spinning, and then into Reverse?

drp

no i dont put it into any other gear, is it recomended i do? Thats exactly what it feels like!!! It keeps spinning!!! I guess i am used to the newer cars that you can just stick it into reverse no problem....

The proper way to put a stick shift into Reverse:

Car must be at a complete standstill. Put the shifter into 1st gear and then into Reverse, while the clutch pedal is depressed. It will go into Reverse. That's the ONLY way I was taught to properly put the car into Reverse. Doing this ensures that the gears line up properly AND to stop any moving gears for Reverse. It's how I was always taught, and it's always worked on the cars I've been in.

Kind of the same deal when taking off from a stop to go forward. I always drag my shifter into 2nd before putting it into 1st gear.

Oh wait no, I'm not. The FB trannies are very strong for the original hp of the vehicle.
