Slow Travel Speed Selected by Quick-Shift Switch:
1. When the conditions, the travel mode switchis in the Hi position and travel speed is less than 10km/h, exist, MC activates the travel mode selector solenoid valve by pushing the quick-shift switch.
2. Pressure oil from the transmission charging pump shifts the travel mode selector valve through the travel mode selector solenoid valve.
3. Pressure oil from the transmission charging pump flows to the clutch slow speed side through the travel mode selector valve so that the clutch is shifted to slow speed.
4. MC stops the travel mode selector solenoid valve by pushing the quick-shift switch again.
5. The travel mode selector valve is shifted by the spring.
6. Pressure oil from the transmission charging pump flows to the clutch fast speed side through the travel mode selector valve so that the clutch is shifted to fast speed.
