OBD-II TROUBLE CODE GUIDE
P0700: Transmission Control System Malfunction
The transmission controller has stored one or more separate fault codes.
What P0700 means
The transmission controller has stored one or more separate fault codes.
Common possible causes
- Transmission-module fault code
- Electrical or voltage problem
- Solenoid, hydraulic, or internal transmission issue
What to check first
Record all stored and pending codes and freeze-frame data before clearing anything. Inspect relevant wiring, connectors, hoses, fluid levels, and obvious damage. Use vehicle-specific service information and test the affected system before purchasing parts.
A code is not a parts order. Several faults can create the same code, and replacing the component named in a code description may not correct the underlying problem.
