What is the P0700 Code?
The P0700 code is a generic diagnostic trouble code (DTC) that indicates a malfunction in the Transmission Control System. This code is often triggered when the Engine Control Module (ECM) detects an issue with the transmission control module (TCM) or the transmission itself.
