P1715 Lincoln Code - Shift Solenoid 'B' Fault
Quick Answer
The Shift Solenoids "A" through "D" are VFS that vary hydraulic pressure by actuating a hydraulic valve. Common causes include Faulty Shift Solenoid 'B', Shift Solenoid 'B' harness is open or shorted, Shift Solenoid 'B' circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1715 Lincoln Description
The Transmission Control Unit (TCU) applies variable current to the shift solenoid which varies the pressure in the hydraulic circuit to the regulator and latch valves of the clutch that in controls.
Shift Solenoid A (SSA) and Shift Solenoid C (SSC) use proportional operation. As the current from the TCU decreases, the pressure from the solenoids decreases. As the current from the TCU increases, the pressure from the solenoid decreases.
With zero current, SSA and SSC fully close the hydraulic valves which apply zero amount of hydraulic pressure to the regulator and latch valves of the clutch that it control and release the clutch.With maximum current to the solenoid, the hydraulic valves fully open for maximum pressure to the regulator and latch valves to apply the clutch.
Shift Solenoid B (SSB) and Shift Solenoid D (SSD) use inverse operation. As current from the TCU decreases, the pressure from the solenoid increases. As current from the TCU increases, the pressure from the solenoid decreases.
With zero current, SSB and SSD fully open the hydraulic valves which apply maximum hydraulic pressure to the regulator and latch valves to apply the clutch that it controls. With maximum current to the solenoids, the hydraulic valve fully closes to apply zero amount of hydraulic pressure to the regulator and latch valves of the clutch that it controls and release the clutch.
