DESCRIPTION
Some vehicles may exhibit an OD OFF light flashing with DTC P1783 stored in memory after driving at highway speeds for extended periods. There
may also be ATF leaking from the transmission vent tube onto the air cleaner box as well as intermittent hard shifting. These symptoms may be caused
by operating conditions that cause the ATF temperature to exceed 135 degrees C (275 F). This concern is most likely to occur after extended periods of
highway driving when air temperature exceeds 100 degrees F.
Customers having this concern should have their vehicle repaired using the repair procedure shown.
