Experince with B&M 50442 - B&M Tork Master Converter

Here is some more info for you. When I start up my engine when its cold it fast idles at 1500 rpm until reaching operating temp and then it drops down to normal idling. My converter used to slip enough for me to easily drop it into drive/reverse at 1500 rpm. Now it's not like that. I could also by holding the breaks rev it up to approx 3000 rpm and then release and take of hard. Now if i try this the car wants to go forward hard even at 1600 rpm.

Some questions I have:
1. can loss of torque from enginge cause such a big differnece? To me the engine runs just fine, I still have more to check though.
2. See the picture above, what do you think this material comes from?
3. Could my problem be tranny releated, or is it the converter?
4. With this material in the oil, ,I need to drop the tranny anyways and have it looked up by a shop?

Tranny was gone trough last summer, have not been driving very much since. Converter swapped to a brand new at the same time.

Need the tranny experts advice here!
