Jere, I went back and re-read your post. I got it partly wrong.

It sounds ike you could well have a leaking clutch master. I'm having
the same problem. I will replace it shortly. However, my clutch fluid
leaks inside onto the carpet.

As for the "Lump" feeling in the tranny --- I had that happen in my 85
GL tranny just before I had to have it rebuilt.

And whatever you do, go ahead and change fluids to the Redline MT 90.
You will never regret it. I have been using it for a number of years
now, and it solved some problems for me. I do change it every two years.
