First Gear, Drive and Second Ranges

Since the shift solenoid valves A and B are ON, pilot pressure operates the shift valves A and B.

Therefore, line pressure passes through the manual valve and the shift valves A and B, and then operates the low clutch. Unlike in the case of first range, the low and reverse brake does not operate and the rear internal gear engaged to the front carrier by the low clutch is locked only against anticlockwise rotation by the low one-way clutch; however, it can rotate clockwise. Therefore, the engine brake does not occur when the accelerator pedal is released.
