Acura MDX ProblemsCheck Engine and D4 Lights Flashing
The Acura MDX may develop issues with the automatic transmission.
Rough shifting may occur, and the “D4” light and check engine may begin to blink. The check engine light will also illuminate, and OBD trouble codes P0700, P0730, P0740, P0780, P1768 and/or P1768 will be stored in the computer.
If the transmission shifts roughly, the failure is very likely mechanical failure of the transmission. If the transmission performs normally, a faulty sensor, or dirty transmission fluid may be the case.
In most cases, it is necessary to use professional diagnostic equipment to provide a diagnosis, and complete the repair.
The longevity of the transmission is dependent on strict adherence to the manufacturer's recommendation for ATF replacement intervals and procedure.
A shudder or vibration may develop while driving at speeds between 35 and 40 MPH. Our technicians tell us this condition is commonly caused by a failed automatic transmission torque converter. It is recommend to replace the torque converter and install an updated powertrain control module (PCM) to correct this concern.
