OK, you guys have talked me through every problem I've faced so far.

I have done all the searches I could but still have a few questions regarding the TKO 600.

For the first 1500 miles, all was well, slipped smoothly into all gears but ground into reverse unless I slipped it into 4th first. So far, sounds normal.

Now, it has gotten harder and harder (requires more and more pressure to get it into first at a stop) and it grinds in reverse now after slipping it into any other gear first.

Shifting into any gear on the run is effortless and no grinding. Even into first while moving is like butter. 2-3 shift has never been a problem. Goes right in.

So, why the sudden grinding in reverse after putting the box in another gear first? And why does it take a good hard push to engage first at a light (no grinding, just a nice firm slow push)?

I have a hyadraulic clutch with no way to adjust the slave cylinder. No rod with any adjusting nuts. Fluid reservoir is full and no leaks apparent.

So, what could be causing the change in gear engagement of first and reverse?

SOLUTION

Everything from the clutch to the master cylinder was as good as new. the problem was the pilot bushing was defective. Binding just enough to cause the input shaft to keep turning even with the clutch fully disengaged. Replaced it, all is good now.
