Is this a tranny or converter problem?

[G-Force]

Lately I feel it takes a little bit more RPM to get the car up to speed. I feel like I am losing torque when I srep on it. The tranny and converter is the original from the factory and car has 61K. Do I need a new trans or converter? Any thoughts?

Hrmmmm

Is it slipping or just not making power? Big difference in the two, for diagnoisis. Also , mainline pressure would be good to know...
