2007 Chrysler Sebring P0700 and P0765 Fault: Transmission Stalls at 45mph and Returns After Restart
I own a 2007 Chrysler Sebring with 147,726 miles. The check engine light activated, and after connecting an ODB-II scanner, I received diagnostic codes P0700 and P0765. I replaced both the transmission solenoid and associated sensors, then reset the system. However, as soon as I reach 45 mph, the vehicle shifts into neutral unexpectedly until it feels safe to re-enter first gear. This behavior has never occurred before. The issue began after a weekend trip in the mountains—upon returning, I started my car the next morning and noticed the check engine light came on for the first time, which coincides with when the transmission problem started. I'm seeking advice as this is a significant issue affecting drivability. Any insights into resolving P0700 or P0765 in a 2007 Sebring would be greatly appreciated.
P0700 and P0765 indicate circuit-related transmission issues—specifically, the Powertrain Control Module (PCM) is not detecting expected voltage signals. The phrase 'next morning I cook my car' appears to be a typo or misstatement; it likely means 'started my car.' Please confirm this detail. A thorough inspection of the transmission electrical harness is recommended. P0765 specifically points to a failure in the U/D solenoid circuit—this may involve three consecutive continuity test failures, or one failure if triggered by gear ratio or pressure switch errors. Additionally, please verify your transmission type (common models include 40TE or 62TE) as this affects troubleshooting.
