Long story short, I picked up a cam/heads 95 Z28 that supposedly had a blown trans. After having the T56 rebuilt, I found that the actual problem was a shredded rear end. Put a set of Motive 4.10's in, all good.
Now since getting it all together, I've had nothing but problems getting the clutch to disengage. The car starts fine, but once it's running, the clutch doesn't seem to be disengaging completely and I have to force it into gear. The car had a Spec stage 2 clutch when I first got it which was way too aggressive for this car. The throwout bearing was also loose since the retaining clip had broken, not sure how long he had driven it like that. I bled the the hydraulics, no change. Replaced the hydraulics with a pre-bled factory linkage, no change. Replaced the clutch/pressure plate with a factory style part from NAPA, no change. New throwout bearing, no change.
Before replacing the hydraulics, I thought the problem was either a bad master or slave. I was able to take the slave adapter off and close the gap about half and inch and was able to get the clutch to release and drive somewhat normally. Figured a new linkage would fix it but no joy. After installing the new linkage, I also noticed that the strap holding the cap on the slave rod did not break after depressing the pedal the first time, as it is my understanding is supposed to happen. Another thing is the clutch fork, it's super loose. I know it's supposed to pivot on the t-bolt, but even after engaging the throwout bearing, it moves over an inch, really sloppy. I've ordered a new fork and pivot, but I want to know that might be the issue before I take this transmission out for a third time. I don't think the fork can be slid onto the throwout the wrong way, can it? It's either on or off I would think. Could the pivot be bad/worn and cause this? Could the fork be bent? I'm at my wit's end with this car. Any help is much appreciated.
