Pinpoint Test Q : DTC P0736
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
- Normal Operation and Fault Conditions
The PCM monitors clutch applications for all gears. It sets a DTC if it detects ratio errors but is unable to detect which clutch caused the issue. The transmission logic disables the gear in question. If multiple incorrect gear ratio DTCs are set, look for a common clutch involved in the operation of those gear applications. If no common clutch errors are found, look for line pressure or pump pressure issues.
