When my T-5 acted like that I had the wrong gear oil in it. The GL5

I thought the internal slave comes with the master as a kit. When one
side goes, so does the other. If the MC was bad, pumping it should make
a difference.

In addition, a bad master cylinder is likely to pump contaminants into your
