The ATF warmer is mounted on the transmission to reduce oil
viscosity frictionby increasing the temperature of oil in cold state,
which in turn improves fuel efficiency It is mounted on the entry of the
Electronic Throttle Controller (ETC) in series, as shown in the
diagram, and minimizes the effects of cabin heating system.
