2003 Dodge Ram 1500 P0605 and P0700 Codes: Do I Need to Replace OEM Solenoids or Address Transmission Issues?
Hello experienced mechanics, I'm currently experiencing P0605 and P0700 error codes on my 2003 Dodge Ram 1500. I'd like to know whether I should replace the original equipment manufacturer (OEM) solenoids in the transmission or if there's a more likely underlying transmission issue. Can you clarify what these codes typically indicate and how to diagnose them accurately?
Do you have access to a scan tool to read TCM error codes? P0700 indicates that the Transmission Control Module (TCM) has detected a fault in transmission operation. This code is most commonly caused by a transmission-related issue, such as faulty solenoids or internal mechanical problems. While it's rare, a failed PCM or TCM could also be responsible—however, this is unlikely. Always use a scan tool to retrieve detailed diagnostic data before replacing components.
