P0983 Shift Solenoid D Control Circuit High

High-voltage fault in the control circuit of shift solenoid D. Ford defines it narrowly as SSD short to power; the open circuit stays with P0765. On the 6R140 the solenoid outputs are run by a smart driver chip (ADLER) that does the open and short checks itself, while older units use a feedback line from the output stage; both need 0.5 to 5 s. Since SSD on Ford six-speeds controls the low/reverse clutch, either alone or through the multiplex valve, a constant power short can apply that clutch at the wrong time. The 2020–2023 gasoline summary keeps the same assignment. GM documents no P0983 for its geared automatics, and Ferrari uses it for an actuator 3 sensor reading too high. Ground faults are P0982.

Likely causes

Solenoid D control wire shorted to a supply
Solenoid D with shorted windings
Conductive contamination between neighbouring pins
Faulty smart driver or output stage in the module

Symptoms

  • MIL on, default gear
  • Clunk or tie-up feel if the low/reverse clutch applies unintentionally
  • Upper gears blocked
