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.
  1. 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.

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    PCM P0736:00 Reverse Incorrect Ratio: No Sub Type Information This DTC indicates a gear ratio error either in or while shifting to reverse. The fault did not last long enough to set a more specific DTC. The failsafe logic disables reverse for the remainder of the key cycle during which the fault occurred.
