Drive - 9th Gear
WARNING: This page is about a different variant/trim than selected.
- Solenoids A, B, 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 shuttles the transmission control valve 1 allowing line pressure to enter Feed 1 hydraulic circuit, which directs fluid to the transmission control valve 2. The transmission control valve 2 directs Feed 1 fluid to the Drive hydraulic circuit. 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.
- Solenoid B allows Drive fluid to enter the 29C hydraulic circuit, applying the 29C Clutch assembly.
