I hear you. When I drive my 07 AT Yaris, one thing that is very different from similar cars with AT is how the tranny shifts up or down only when absolutely needed and not more. Few downshifts when gas pedal is pressed moderately. It actually reminds me old style hydraulic logic AT action when gear depended solely on speed, unless one pressed gas to the max and then it would downshift. I'm thinking this is limiting unnecessary shifts for durability. When I dropped the pan to replace fluid and filter at 66,000 miles, there was little clutch debris in the Yaris AT's pan. Small fraction comparing to Corolla when I did a similar service at 60,000 miles. Now, there are some technologic differences that can additionally account for the debris difference in Yaris:
Throttle by wire
Full flow AT filter
WS synthetic fluid
etc.
