What does P0783 Mean? The PCM has detected an abnormality in 3-4 shift function. The computer controlled automatic transmission uses shift solenoids to manage the transfer of fluid between hydraulic circuits and actuate a change in transmission gear ratio. Varying gear ratios are needed to increase and decrease vehicle speed, maximize engine performance, and optimize fuel efficiency. engine code P0783P0783 fixobd P0783dtc P0783obd code P0783obd2 P0783P0783 car codediagnostic code P0783car code P0783check engine code P0783fehlercode P0783P0783 fiatcodigo P0783codigo falla P0783P0783 kody b??dówcodigo de falla P0783 What are the common causes of P0783 ? Low transmission fluid level Dirty transmission fluid Faulty shifting solenoid valve Shifting solenoid valve harness is open or shorted Shifting solenoid valve circuit poor electrical connection How do you troubleshoot P0783 ? Like the all engines, the car engine system employs specially developed hydraulic lifters (known as switching roller followers) for the P0783 code intake and exhaust valves. The lifters can be collapsed by disengaging an internal locking pin. The locking pin is disengaged using solenoids to alter oil pressure fed into the lifter.
