Description

What is a transfer?

It is installed at the rear of the engine and outputs the driving force from the transaxle differential case to the rear by changing the direction by 90 degrees.
In the 4WD system installed in the GR Corolla and GR Yaris, the driving force to the rear axle is controlled by an electronically controlled coupling installed in front of the rear differential.
It is a mechanism that constantly adjusts the driving force to achieve the ideal driving force distribution in each mode (Normal, Gravel, Track).

Description

Since the transfer oil temperature of the GR Corolla and GR Yaris tends to rise during continuous high-load driving on circuits, etc., a 2WD protection control (transfer protection control) is adopted to prevent the transfer oil temperature from becoming abnormally high.
The HKS TRANSFER OIL COOLER was developed to extend the life of transfer oil and protect transfers, focusing on the fact that the temperature of the transfer oil tends to rise.
For vehicles equipped with the Transfer Protection Control Cancel Program, it is possible to activate the cancellation program (cancel the 2WD conversion), and even if you drive continuously on the circuit, it will not become 2WD. (If you activate the cancellation program, it will not be covered by the car manufacturer’s warranty.) For more information, please check your car’s warranty policy. ）

Without the transfer oil cooler installed, the oil temperature continued to rise, but the test was stopped when the oil temperature reached approximately 150°C.
With the transfer oil cooler installed, the oil temperature stabilized at around 100°C, and the test was stopped.
Based on these results, if we estimate the temperature at which the oil temperature will saturate if the race continues, the temperature difference with and without the transfer oil cooler is expected to reach approximately 50°C. With the transfer oil cooler installed, the temperature can be stably maintained at around 100°C even during continuous driving.

The transfer protection control cancellation function is available for vehicles manufactured from 25/4 onwards.
The transfer protection control cancellation function does not apply to other vehicles.
The wiring and operation of the pump controller differ between vehicles equipped with the transfer protection control cancellation program and those with earlier models.
