Switching Logic For Solenoid Valves

Switching Logic
The solenoid valves 1, 2 and 3 are the actual shift valves of the transmission.
The solenoid valves 4 and 5 are gear change valves. They are only used as auxiliary valves for upshifts and downshifts to facilitate "smooth" gearshift.

NOTE: Power is cut to all the solenoids in the event of the transmission control failure.
