What Causes Clutch to Drag.

[jhv48]

If you've read my previous posts, I have a TKO 600 that grinds going into reverse, no matter what you do first, and is tough to slip into first gear at a stop. All other times, it shifts beautifully, both up and down. Ran fine for 1500 miles. Problem just started.

I checked and replaced the slave, master cyl. bled the system. The slave pushes the fork about 1 1/2 inch. No leaks or air bubbles. Both are 7/8 inch bores. Standard SPF units.

Clutch is properly adjusted so it engages about 2 inches from the floor. No slipping is present.

We pulled the trans and examined the clutch. Everything looks fine. No warps, no oil, no glazing, nothing appears bent, warped or abused.

So, what else is there. And, like I said, the car only had 1500 miles on it of all street driving when the problem cropped up. Tremec said that it's not the tranny. Got to be something wrong with the clutch.

So, what do I check next? I really don't want to replace all the clutch components, but also don't want to button it back up and have the problem persist.

Experts feel free to float a solution here. I have a day or two before we put it all back together.

SOLUTION

Pilot bushing was causing the input shaft to turn when the clutch was depressed, thus causing grinding in reverse and difficulty pushing lever into first from a stop.
