P0950 Auto Shift Manual Control Circuit

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

General electrical fault in the circuit that carries the driver's manual up and down requests to the transmission control, as used by tip-shift gates on automatics and by automated manual gearboxes. A Chrysler patent shows the classic design: a transverse gate beside the drive positions with a proximity switch that signals upshift on one side and downshift on the other. No manufacturer documents this exact code publicly. The module typically checks the switch signals for states that cannot occur. P0951 to P0954 are the range, low, high and intermittent faults, P0955 onward the mode select circuit. Usually manual shifting is disabled while normal automatic driving remains available; MIL use varies.

Likely causes

Failed up/down switch or sensor in the selector lever or paddles
Damaged wiring or corroded connector at the shifter (e.g. after spilled liquid)
Clockspring or steering column wiring fault on paddle-shift vehicles

Symptoms

  • Manual or tip shifting does not respond
  • Gear display or warning message
  • Automatic mode still works normally

Repair estimate

DifficultyMediumDIY possible
Parts and labour€40–450
Time0.5–2.5 h
