Diagnostic code P1782 - 1999 Dodge Caravan

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.

Okay i have a 1998 dodge ram 2500 and i ran a obd ll and it gave me those same codes so i dropped the trans pan and filter , replaced the pressure sensor and the solenoid ,new oil and filter and my p/u runs great and i also changed the shift sensor . You then take the bolts out of the pump plate which is the one that holds the filter or you wont be able to get to the pressure and solenoid , i bought the gasket ,filter ,shift sensor ,pressure sensor and solenoid for $70 but if you buy these parts separate it can get costly at around $250 and thats not including the type of trans oil type plus.

First things first don't assume the trannys bad if you scan this code that you need a mechanic or transmission needs replaced first think back have you been having trouble imtermitently for a while? Then you might want to take it to a mechanic or was there an event that happened before you started having issues with it such as stuck in the snow, deep mud water hit a road hazard? Everything worked fine until then you should take a look at the hoses, connections, etc. You may have knocked a wire loose, damaged a hose or sensor. Easy to see and repair. Most of the time transmissions last as long as the van if you take care of it. If its fine one day and not shifting the next like mine the transmission is most likly fine I am sure after being the victum of a month of being burried by our rude snow plow operator I damaged someting external when I got stuck on a huge iceball. It knocked a hose off fixed that and replaced fluid so checking wires now since this poor van was so abused before I obtained its a wonder it runs at all. But the tranny and engine are the only things that have no issues its everything else thats falling apart! Check the little things first before you go to a mechanic. A loose wire, low fluid pressure, and such will cause the tranny to malfunction and you will get codes saying that because it is not wirking right fix the cause of the malfunction all codes go away remember the diagnostic system will list many codes because the transmissiin is very complex this does not mean its toast it can't decide so it list everthing that is effected because one little thing got jnocked loise or a hole in a hose. Save yourself being raked over the coals.
