Code P0780 2021 Honda CR-V Description

The P0780 diagnostic trouble code (DTC) in a 2021 Honda CR-V indicates a shift error within the transmission. This code specifically relates to an issue with the shift control system, which is responsible for managing the transmission's gear shifting process. When this code is triggered, it means that the transmission control module (TCM) has detected a problem with the shift solenoid C circuit. This can lead to improper gear shifting, causing the vehicle to experience issues such as harsh shifting, delayed shifting, or even the transmission getting stuck in a particular gear.
