Re: 2003 dodge caravan with po750 trans code.. replaced...

P0750 = Shift solenoid A - circuit malfunction. Probable cause: wiring, shift solenoid, Engine Control Module (ECM) / Transmission Control Module (TCM).
TCM electronic control unit (TCM ECU) can be accessed using a diagnostic scantool connected to the Data Link Connector (DLC) of the car. After TCM ECU memory scaning from internal errors, (Diagnostic Trouble Codes - DTC memored), you will be able to know exactly what piece is damaged. After bad piece replacing you will be able to erase the TCM ECU memory from internal faults, and reset TCM ECU = exit transmission from 2nd gear.

04 dodge neon with codes po700 and po750 what are these and how can I fix this car runs fine but wont shift out of first gear


Code 700 is a generic code that means there is a problem with the transmission or the control module. Code 750 is for a problem with the low-reverse solenoid circuit.
The circuit and the trans control module would need to be checked. A shop manual will be necessary to get the testing procedures.

Diagnostic code P1782


P1782 DODGE - 2/4-OD Pressure Switch Circuit Possible causes of this code are: - Low transmission fluid level (check level hot transmission only)
- Dirty transmission fluid (has transmission been serivced at least every 60,000 miles, fluid and new filter?)
- Faulty 2/4-OD Pressure Switch
- 2/4-OD Pressure switch poor electrical connection
- 2/4-OD Pressure switch circuit is open or shorted
P1782 DODGE Description The pressure 2/4-OD Pressure Switch is part of the pressure switch of the transmission. The pressure switch are located in the solenoid assembly. The switch provide input information to the Transmission Control Module (TCM). The switch will inform to the TCM is pressure exist in a specified hydraulic circuit. the TCM uses this information to verified that the solenoids are working or not.

Diagnostic code for dodge caravan 1996 P1784?


The code is about the switch that monitors the hydraulic pressure for operating the low/reverse clutch of the transmission. That clutch is called into play for all forward gears as well as reverse, so it seems reasonable if that clutch were not working that the car wouldn't move in any gear. I would begin by making sure that there is sufficient trans fluid by inspecting its dipstick. If needed only use ATF +4 but don't overfill it. Also, just on a chance, take a look underneath to see if you see any motion of either the left or right half axles (or one moving, but one not) which would be another reason for no motion due to a drive shaft disconnection or some such anomaly. Other than that, your problem could be with the Low/Reverse solenoid switch in the solenoid pack portion of the transmission (the box on the driver's side of the trans) being stuck. That can be repaired without removing and rebuilding the transmission so let us hope that may be the cause. I would have the car towed to a good independent trans shop that has a reputation for knowing how to service the Chrysler electronic transmission.

Hope this helps.

The speedometer is not working and the trans. seems like it's not going into 2nd


computer diagnostic will give you codes to repair vehicle better but sounds like you need to replace Vehicle Speed Sensor (Output Speed Sensor) On a 31TH TRANS sensor located near the transaxle extension housing, on the 41TE trans located between the module and the park/neutral switch (black)
