dude, under the dash ... get down there and look at the pedal. You are going to see a rod that physically pushes into the master cylinder through the firewall (sorta like a penis i guess). Well you just gotta adjust it's nuts so that it pushes in further.

cup'em further back? lawlz

hadn't even tried starting the car before i noticed it when bleeding the clutch line. but i've had a car with a leaking slave and another with a bad master and both exhibited those symptoms.

it's quite simple. the clutch is not disengaging for you. when the car is running the trans is designed not to pop into gear easily without disengaging the clutch. now you just have to figure out why it's not. you have a few choices.
  1. faulty master
  2. leaking slave
  3. air in line
  4. not fluid being pushed due to inproperly adjusted clutch pedal
  5. stuck slave
  6. you are pushing the wrong pedal

if there is the normal or more resistance in the clutch pedal and the clutch slave piston is not pushing out my money is on the slave being bound up. none of the other things would result in that. 1,2,3,&4 would result in a softer pedal.

There is no leak, so only thing to check is the adjusting clutch pedal and slave not extending fully.

did you use same clutch or this new clutch setup,sound like defective pressure plate or stock up tranny,happen to me last year i got a defective pressure plate from act.

Its a new act clutch not the same one that was on the car. I try to adjust the pedal and no luck. I will try to bleed the slave again and might take it apart. I hope its not a defective clutch. I hate to take it apart again.

Tell you what can you start the car out of gear and then shift throught he gears while it is running? +1 on air in the lines etc.

cardriverx 10-08-2007 08:02 PM

Im telling you try a longer shaft between the slave and clutch fork. A hardended bold rounded off works really good.

It shift when the car was not running and it doesn't shift at all, when the car is running.

then the clutch is not moving for somereason. you have air or a mechanical failure of the hydraulic system. Bleed it with a vaccuum bleeder etc and also get down there and watch the slave to see if you get any motion out of it. adjusting the rod into the master will help you compensate for this but i doubt it will 100% cure the problem. bleeding it however will most likely fix the issue. also i find it helps to manauly move my slave while trying to bleed it the first time to kind of prime it.

supra441979 10-08-2007 09:02 PM

I just bleed the clutch by the slave cylinder and that didnt do anything. Also I hook the slave apart and the rod does not look like its bent. Will try a longer rod tomorrow. I can see the slave cylinder moving when the clutch pedal is press though.

dude...the lil rod attached to the clutch pedel needs to be pretty much ALL the way out for it to work...same issue I had and have with my ACT clutch....ya need a 10mm and a 12mm(if memory serves right)....get that lil rod out as far as safely possible and you should be good....If its something else..you have my condoulences...cause dropping the tranny twice sucks balls....(been there done that)

thats how my clutch was too

supra441979 10-08-2007 10:54 PM

I will try to extend the rod all the way in tomorrow.

supra441979 10-09-2007 12:09 AM

All the way out as in the closer to the 12mm nut right? (towards back of the car)

magnamx-5 10-09-2007 08:13 AM

Make it longer yeah. dude my ACt XD clutch did the same stuff. Do you have a vac bleeder?

longer as in towards the back of the car right? also no i dont have vac bleeder i used the one man bleeder from harbor freight ones and have someone pump the clutch pedal

supra441979 10-09-2007 08:25 PM

Well guys I try to adjust the rod and it didn't do the trick. Looks like I'll be taking the tranny out and swaping out the clutch again. :vash:

Did you try a longer shaft between the slave and fork like I said?

Gloko 10-09-2007 10:48 PM

I can almost gurentee its the rod length....The ACT takes quite a bit more pressure to compress over stock.. so the stock clutch hydros have problems....I know how ya feel though cause this same shit happen to me and its been so long I forgot how I ended up fixing it....I sorta remember pulling off the clutch master cylinder and putting a extender piece or "bit" in between the rod and plunger.....been too long, sorry...

I guess I can stick on long skinny bolt on that and try it. It just doesn't make any sense to me. I had ACT clutch on it right before I swap the motor and All I did was swap the motor and swap with new ACT clutch and it doesn't go in gear when running.
