System Features and Functions
The front of the TransTech™ III+ cabinet contains the control panel, the fluid fill neck for adding new
transmission fluid, and the fluid level windows.
Automatic Flow Direction Detection
The TransTech™ III+ is capable of automatically sensing the direction of fluid flow in the
transmission cooling circuit and aligning the flow internally. A dual one way filtration system
ensures that internal filters are never backflushed into a vehicle.
MODE Button
– Press and hold MODE button 5 seconds until the alarm sounds. After releasing the button

issues.
