Lately in the mornings the clutch feels very lite and it's hard to engage 1st and 2nd but after about 15-30 min it feels a little stiffer "thereís actual press" when you push down on it the gears are smooth form 1st to 5th no problems engaging. After the car sits a while at work same thing all over again.

Iíve checked fluid levels and all is fine
No leaks

What could be causing this? Any advice is appreciated

Thanks

Sounds like a slave cylinder to me. Its hard to shift because its not fully disengaging the clutch. Try pumping the clutch a couple of times before shifting the car at all. That should help after it sits a while. Also, it will probably get worse to a point where you have to pump the clutch every time you push it. Been there before. I guess it could also be the clutch master cylinder instead, but Ive seen way more slave cylinders go out.

joesfiero thanks and I'm going to look into the slave cylinder first. Even before I do that I'm going to drain and add new fluid and bleed the line just in case.

Thank you for your advice greatly appreciated

I've been procrastinating on this issue and now it's bit me in the A_ _ any how . Today the petal just went free flowing only after pumping it consistently did I get a little pressure going. I managed to get home, I did a bleeding and it just went back to the way it was before which was pump a few time 3-5 and then with a little trouble it would engage. I check for leaks and I have none not at the master cylinder or the slave. My question is could the slave be bad and still not leak? is this possible?

Need anyone's help asap as this will determine if I go into work tomorrow or stay home to take care of my baby (my fiero that is)

thanks a million

When the pedal drops like you described, it sounds like the slave seals are gone. Get a new slave cylinder, bench bleed it before installing it, and then gravity bleed it, to make sure all the air is out. You can also push the slave push rod into the slave body and close the bleed screw, to get the last of the air out.

First of all is it hard to shift when the car is off? If so it could be a cable issue. Try greasing and adjusting the cables

Yes, the slave 'could' be bad and not leak, but usually the symptoms are different than what you describe.
In your case, I would suspect the master cylinder. Hard to find a leak, because the fluid is often hidden under the floor carpet, or the seals in the master are just bypassing--but not leaking to the outside. Pumping the pedal forces the seals out and seals them off enough to pump up pressure, but just pressing the clutch in normally will not do the same thing.

Have you lost any fluid from your clutch master cylinder?

I have the same problem with my Indy. After it's been parked I have to pump the pedal about 20 time to build pressure back up to be able to shift.

Bleeding won't help, you have a bad seal that is allowing the system to lose pressure.

My experience is that the master will go bad and cause this. I'll let you know what happens after I replace the master.

If the system is not losing fluid then it's usually an internal seal in the master versus a slave that will leak externally.

Thank you all for you input, it turned out to be the slave cylinder. I put it in and it shifts like brand new. There is pressure through out the entire pedal travel and it engages beautifully.

Again thank you all for your help.

Now I only have to change the oil pan to get rid of a tiny little oil leak and that's it I'll be ready for the Punta Gorda show.
