Torque Converter

The torque converter is equipped with a lock-up clutch. The lock-up clutch closes depending on load and speed.

ATF

ATF is a permanent fill. ATF does not need to be changed during maintenance.

The ATF levels inside the planetary gear and inside the final drive are checked and filled at the same time.

Drained ATF must not be used to fill again.
