Low-Reverse Clutch Hydraulic Circuits

WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

When the low-reverse clutch is applied in REVERSE, LINE pressure from the pump is directed to the multiplex shift valve by the manual valve through the REV hydraulic circuit to move the valve. Line pressure is also supplied to the low-reverse/overdrive clutch regulator valve from the pump. The low-reverse/overdrive clutch regulator valve is controlled by SSD and directs regulated pressure to the multiplex shift valve. The multiplex shift valve directs the regulated pressure to the low-reverse clutch through the CBLR SUPPLY circuit.

When the low-reverse clutch is applied in PARK, LOW or 1st gear below 8 kmh (5 mph), SSE pressure is supplied to the multiplex shift valve to move the valve. LINE pressure is supplied to the low-reverse/overdrive clutch regulator valve from the pump. The low-reverse/overdrive clutch regulator valve is controlled by SSD and directs regulated pressure to the multiplex shift valve. The multiplex shift valve directs the regulated pressure to the low-reverse clutch through the CBLR SUPPLY circuit.
