As the vehicle speed increases, the transmission control module (TCM) receives input signals from the automatic transmission input and output speed sensors, throttle position sensor and other vehicle sensors to determine the precise moment to energize or turn on. Shift solenoid valve C is commanded ON and Shift solenoid valve A is commanded OFF. 2-3-4-5-7-9-10 Clutch Applies 2-3-4-5-7-9-10 Clutch Regulator Valve Shift solenoid valve C is energized and applying pressure against the 2-3-4-5-7-9-10 clutch regulator valve allowing LINE (2) fluid to enter the 234579-10 CLUTCH (27) fluid circuit. 234579-10 CLUTCH (27) fluid is directed to the 2-3-4-5-7-9-10 clutch assembly. Fluid is also directed through orifice #70 to the #6 check ball valve. 2-3-4-5-7-9-10 Clutch Assembly 234579-10 CLUTCH (27) fluid is directed through orifice # 19 into the 2-3-4-5-7-9-10 clutch assembly. 234579-10 CLUTCH (27) fluid moves the piston against spring force to apply holding of the 2-3-4-5-7-9-10 clutch plates. 1-2-3-4-5-6 Reverse Clutch Releases 1-2-3-4-5-6 Reverse Clutch Regulator Valve Shift solenoid valve A is signaled off allowing 123456 CLUTCH (21) fluid to exhaust through orifice #5 and into the 123456 CLUTCH EXHAUST (23) fluid circuit. 123456 CLUTCH EXHAUST (23) fluid is directed to the exhaust backfill blow off valve through the EXHAUST BACKFILL (39) fluid circuit.
