Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Shift High Range and Low Range
When the car is stops (less than 2km/h or 1.2 mph and less than 1500 rpm), the AT selector position is neutral, the brake is applied, and the TOD switch is changed to 4L from TOD (or to TOD from 4L), the high-low shift motor starts by power applied from the TOD control unit and turns the shift shaft through the worm gear.
The shift shaft turns the shift cam through the torsional spring.
The end of the shift cam moves the lockup shift fork and the spiral groove on the outside of the shift cam slides the high-low shift fork.
