Drive - 8th Gear
WARNING: This page is about a different variant/trim than selected.
- Solenoids A, C, G, H and PISA are on. Solenoid G shuttles the mode enable valve to provide line pressure to transmission range control valves. The PISA is held on to prevent an unintentional parking pawl engagement if hydraulic pressure at the park servo is lost.
- Solenoid C is PWM in order to create a pressure high enough to shuttle the transmission range control valve 1 and the 38C regulator valve. This allows Drive fluid to enter the clutch selector valve, which directs Drive fluid into the Drive 2 hydraulic circuit. The 38C Regulator valve directs Drive 2 fluid into the 38C hydraulic circuit applying the 38C Clutch assembly. Solenoid A does not allow Drive fluid to enter the 123456C Feed hydraulic circuit.
- Solenoid H allows line pressure to enter the TCC VFS Hydraulic circuit, shuttling TCC Control Valve and TCC Reg Apply Valve.
- Line pressure is now able to flow through Solenoid F into the 1 Rev/6789C Clutch Feed hydraulic circuit. 1 Rev/6789C Clutch Feed fluid is directed into 6789C Clutch hydraulic circuit by the Clutch Selector Valve, which applies the 6789C Clutch Assembly.
