Modulator Valve

COAST CLUTCH
This valve adjusts the hydraulic pressure to the coast clutch when the gear is in the 1st, 2nd and 3rd and R ranges.

The hydraulic pressure (line pressure) coming through (2) passes the fluid passage in the valve, enters chamber (A) and pushes the valve downward. At the same time, however, as spring force pushes the valve upward, the hydraulic pressure is adjusted and applied through (1) to the coast clutch.





LOW COAST
This valve adjusts the hydraulic pressure to the 1st and Reverse brake when the gear is in the "L" range.

The hydraulic pressure is fed from the manual valve through (1) and after being adjusted in the valve, it is transmitted through (2) and 1 - 2 shift valve to the 1st and Reverse brake valve.
