Other cars I have owned had transmission control computers that "leaned" from your driving patterns and adjusted shift points accordingly.

Soooo....

How smart is the control programs used by Toyota transmissions :?:

Disconnecting the negative battery cable and turning on the ignition will reset the CMs in vehicles that I've worked on in the past, but it will also erase diagnostic codes that have been set in the PCM and TCM.

Found this in the online shop manual

The Electronic Controlled Automatic Transaxle
(ECT) is an automatic transaxle that electronically
controls shift timing using the Engine Control
Module (ECM). The ECM detects electrical signals
that indicate engine and driving conditions, and
controls the shift point based on driver habits and
road conditions. As a result, fuel efficiency and
power transaxle performance are improved.
Shift shock is reduced by controlling the engine and
transaxle simultaneously.
