Question about Chrysler Town & Country
2002 Chrysler Town and Country 3.8 after driving at highway speed for about an hour, experienced a "jerk and sharp spike in rpms" followed by "loss of power." After pulling over, shifted to park and back to drive and no engagement; checked other gears and no engagement. Checked tranny oil - level and color appear normal. Shifts normally and no unusual sounds. manual key check revealed codes: p1684 and p1698 other than noted below, have not experienced any difficulty with shifting; trans oil changed mid-november note: last august the previous owner had the tcm replaced with one pulled from another vehicle because it was in lim in mode and the shop that did the work did not program it and owner was told engine light and prndl would remain lit until this was done at a dealership.

It appears that you have a power connection issue. First thing you will want to do is to clean the battery terminals really well. Wear safety glasses when disconnecting and connecting the cables. Batteries produce hydrogen, when charging. Very explosive. I have had this happen to me without safety glasses on. Not good. NEXT thing is to ensure that the connections on the computer are plugged in solid. Also, make sure that the connection on the transmission is plugged in solid. You have lost power to the TCM (Transmission Control Module). Most likely cause is the connection on the battery. If this connection gets really poor, it could take all of the alternator power, just to try to jump that bad connection and recharge the battery. Also, all modern cars are very susceptible to low voltage. Computers have a hard time working when the voltage drops below 12 volts. Clean connections and you should be good to go. Then go to an auto parts store and have them check the codes. They will let you press the "clear codes" button and clear the codes.

Code p 1684 refers to battery disconnected within last 50 starts
indicates a loose battery terminal wire or bad ground connection broke the electronic circuit to the ECM and /or the TCM
code p 1698 refers to no CCD messages received from PCM take the vehicle to an accredited service center that has experience on your make of vehicle and have it properly diagnosed

Your transmission fluid contain water,thats why the colour of the fluid changed to pink.And of such the clutch is slipping causing the engine to reve up before shifting - Check transmission cooler.

Your going to have to get the car scanned for the DTC code. The Check engine light indicates that the ECM has detected an issue with the cars engine or transmission performance. Your hard shifting could be the failure to the Pressure control solenoid (PCS), that would be a DTC code P1811. The PCS is located under the trans axle side cover assembly. IF you go to Auto Zone, they can scan your car free of charge and can give you the step by step instruction to replacing the part that may have failed. Good luck and keep me posted, be glad to help.

I would get your wheel sensors looked at. (Most vehicles have them incorporated into the wheel bearing for the front) If you are getting a false reading at a wheel, your ABS will engauge.

You need to change out the tranny fluid completly and change out the filter as well. The pump in the tranny seems weak and the fluid may be getting dirty and heavier and harder to pump.

The only reasonable part is the labor charge. I couldn't second-guess the shop's recommendation, maybe both parts are needed, but you could have them replace the shift solenoid, and try driving it for awhile, see what happens. Then if you need the TCM, try a used one from a salvager for less than half the cost of new. That is something you could install yourself.
Whatever you decide, good luck.
