no, the gen4 doesnt have an ECT option and as far as i know you cant install it.
and yes, most toyota transmissions are designed to be economic so they hunt for the lowest RPM to save gas. thats whats great about the pre 97 V6 auto. it could be economical but when the ECT button is depressed the tranny becomes more sensitive to downshifts and holds RPMs longer.
