Intermediate (2, 6) Clutch Hydraulic Circuits (Applied)
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
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 SSC is hydraulically off and the Manual Valve is in DRIVE, the Clutch C circuits are filled with fluid from the CL EXH circuit under low pressure, (21kPa/ 3 PSI). This keeps air out of the Clutch C circuits resulting in smooth shifts when the clutch is applied in 2nd and 6th gear.
