P0700 - Transmission Control System Malfunction

The Technical Definition: This code indicates a malfunction within the transmission control system.

Common Symptoms: The check engine light will turn on, and you may experience harsh shifting, failure to shift, or the transmission going into a protective "limp mode."

Typical Fix: This is a broad, generic code that the transmission control module uses to request the check engine light to turn on. It requires a transmission-specific scanner to read the deeper, underlying transmission codes to pinpoint the exact mechanical or electrical failure.
