Low/Reverse Clutch Hydraulic Circuits
To apply the low/reverse clutch, the manual valve can be in any position. Line pressure is supplied to the D1 regulator and latch valves through the PUMP circuit. SSD provides regulated solenoid pressure from the SREG circuit to the solenoid multiplex valve through the VFS4 circuit where it is directed to the D1 regulator and latch valves through the CL DC circuit to position the valves. The clutch D1 regulator valve provide regulated line pressure from the PUMP circuit to the CL D1 circuit to apply the low/reverse clutch.
Low/Reverse Clutch Hydraulic circuits Applied In PARK, REVERSE, NEUTRAL And 1st Gear
In 2nd, 3rd, 4th, 5th and 6th gear, the D2 Latch valve directs a small amount of fluid from the PUMP circuit the CL EXH circuit. When SSD is hydraulically off and the Manual Valve is in DRIVE, CLD1 circuits are filled with fluid from the CL EXH circuit under low pressure, (21kPa/ 3 PSI). This keeps air out of the CLD1 circuit resulting in a smooth downshift into 1st gear.
