6th Gear Solenoid Hydraulic Circuits with the TCC applied
WARNING: This page is about a different car, the 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
In 6th gear, the overdrive (4, 5, 6) clutch remains applied. SSB releases pressure to the 35R regulator and latch valves. SSC applies varying pressure to the 26 clutch regulator and latch valves through the VBS CB26 hydraulic circuit to apply the intermediate (2, 6) clutch.
The TCC can be applied in 4th, 5th or 6th gear. To apply the TCC, the TCC solenoid applies pressure to the TCC regulator valve and the TCC control valve to position the valves to apply the clutch.
