P1DDC Chrysler Code - Transmission Control Module Monitoring Processor Performance Unallowed Reverse Engagement
Quick Answer
The Transmission Control Module (TCM) monitors the pressure regulator and solenoid logic to detect a failure in the activation of the pressure regulators and solenoids. Common causes include Faulty Transmission Control Module (TCM), Transmission Control Module (TCM) harness is open or shorted, Transmission Control Module (TCM) 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.
