3. Check the rod on the slave Cylinder and Lever.



Perhaps this goes without saying... but check the length of the rod before pulling the tranny!

Easiest way to determine if the rod isn't too long is to clamp some vice-grips onto it, and make sure you're able to pull the rod further into the slave. If you can't pull the rod any further in, the slave may be bottoming out.

85 V6 Fieros did not have a 5 speed transmission originally.....so you need a clutch that matches the trans you have, whatever it is. Archie is still to be found on the web, so you should probably contact him to find out what you have now (or describe the cable connections and we can tell you).

Thanks to Gall757 and Patrick for the additional suggestions. Will do that before pulling the tranny.

Did it operate properly prior to being placed into storage?

To be honest... When i picked it up from V8 archie( back in 2013 when he had his shop in IL), We took it for a test drive. It was a bit of a rough ride and the car would shake momentarily when i would put it in gear but I could feel the punch. I thought I just need to break it in. I already had about 150 lbs of chassis reinforcement at that time. That was the last time i drove it before completing the diablo kit on it. since then I added prob another 100 lbs for additonal chassis work plus the 19 x 11 wheels. I would start the motor once a month and let it run for about 15 mins. Just to hear it. ha ha ha

I noticed the clutch issue last year when i was driving it up onto the flatbed. Trying to drive up the inclined flat bed was a task. I had it in 1st gear with my foot on the pedal and it was barely moving up the flatbed.

Even with the added weight and increased rotational mass, the V-8 should move the car quickly.
Before pulling everything apart, I would check the throwout arm shaft for binding. Perhaps the long period of storage has allowed some corrosion that is preventing full rotation of the shaft when releasing the clutch.

A squirt of penetrating oil might save you a lot of work and money.
Shoot some on the top of the shaft under the throwout arm and pump the clutch pedal several times.

I have an 85 Fiero based Lambo Diablo Roadster replica. It original had a 5 speed 2.8L,

5-speeds were not offered in 1985 for the V-6.

I find it hard to believe that Archie would anything out of his shop that wasnt road tested and in proper order.

Thank you olejoedad for the recommendation
I hope to try that this weekend. I will update you on the progress.

You are correct. I should have clarified that the my replica had the 4spd replaced with a 5spd before i took it to V8 Archie
