P0982 Shift Solenoid D Control Circuit Low

Low-voltage fault, in practice a short to ground, in the control circuit of shift solenoid D. Ford is the documented user: its summaries list SSD with P0765 open, P0982 short to ground and P0983 short to power, checked continuously through the driver feedback within 0.5 to 5 s. Which clutch this hits depends on the gearbox. In the 6R80 and 6F, SSD is a variable force solenoid feeding CBLR or C456 via the SSE multiplex valve; in the 6R140 it drives CBLR alone. In the 2023 diesel summary SSD is fed from supply TSPC2 with SSB, the converter clutch and line pressure solenoid. GM's six-speed and Allison tables do not use P0982. Ferrari reuses it for an actuator 3 sensor reading too low.

Likely causes

Solenoid D control wire shorted to ground
Internal short in solenoid D or the main control assembly
Damaged internal lead frame or connector inside the transmission
Faulty driver in the powertrain or transmission module

Symptoms

  • MIL on and default gear operation
  • No engine braking in first or no reverse, depending on gearbox
  • Harsh shifts into upper gears
