Chrysler town and country

I took the 3.8 good motor from my old 1999 town & country, and i bought a 2002 town & country with a 3.8 bad motor. Will the good engine from the 1999 fit in the 2002, and if so, what parts would not work, for the engine.



The engine will fit. However you will be giving up horsepower.

  • 1998–2000: 3.8 L EGH V6, 180 hp (130 kW), 240 lb⋅ft (330 N⋅m)
  • 2000-2007: 3.8L EGH V6, 215 hp (160 kW), 245 lb⋅ft (332 N⋅m)

The long block of each engine should be the same so all other existing components should bolt up with ease.

van is fine under 45 mph. Once over 45, it starts to “bump” – rough ride like something is wrong with a tire or something. (tires are fine.)



Is it the torque converter?

If your car shakes and shudders, it could mean the lockup clutch is malfunctioning. This might occur at speeds around 35-45 miles per hour. It’s a noticeable problem and feels like you’re driving on a road with lots of small bumps. A worn out lockup clutch can make the transition from acceleration to direct drive difficult, and it’s a sign that you need to have your transmission checked.

Chrysler 300How does the wiring harness on the anti-lock brake control module unhook? Is there something I have to do to be able to pull it off?  Did not want to pry on it too much. Was wondering if there is a release somewhere on it?



  • Depress tabs on each side of connector cover, then
  • Pull outward and upward on the lower half of cover until it locks into position pointing straight outward(2). Connector can then be pulled straight outward off ABM(1)

I was told I have a blown head gasket but these guys just seemed so unprofessional and would not answer any of my questions. So I’m wondering can it be a blown head gasket if there is no coolant leaks no misfires no white smoke. The only symptom my car has is it overheats when the car warms up when I stop the coolant in the overflow tank is boiling or bubbling. When they ran tests the said there was combustible gases in my coolant. Thank you.



If you are uncomfortable with the mechanic shop you took your car to, exercise your right to take it somewhere else. A compression test is a good place to start when diagnosing a blown head gasket.

A pressure gauge can be installed to the cooling system to detect excessive pressure. Most cooling systems pressure is under 20 psi. When engine cylinder compression enters the cooling system the pressure gauge would spike and exceed this amount. An engines compression in each cylinder can be 100 psi or more.

Boiling Coolant

Boiling coolant usually indicates a poor mixture. The coolant to water ration should be 50/50. Straight water will allow the engine to overheat quickly. So if the cooling system has been worked on recently and just topped off with water, it may be the cause.

Low Coolant

When the cooling system is low on coolant it will overheat as well. If this is the case, finding the leak and repairing it would be the best course of action.

1964 Chrysler 300K

I have a 413CI RB big block in this car. I am needing to replace the rear main seal next week, so I am shopping for a seal kit. These are the options I have, which would be the best choice? 1. Felpro 2-Piece, Fluoroelastomer seal; 2. Mr Gasket Rear Main Seal, 2-Piece Silicone; 3. Felpro 2-Piece, Rubber Rear Main Seal; or 4. Felpro Rear Main Seal, 2-Piece, OEM-Style Rope Thanks



To narrow down the choices one might consider the installation tools. You will need a rear main seal installation tool with a bridge to install the rope seal properly.

An example of installation of rope seal without the proper tool.

I wouldn’t venture to say that any one seal is the best choice. They are all designed to perform the same function.

Engine cranks but will NOT turn over. Changed battery, and got P1684-ECM reset code, no other codes follow. Check engine light flashes 5 times after initial “on” position. Not sure how to calculate the flashes. Need to know the flash count calc. Please advise.


Ok, I’m thinking that the PCM…aka engine computer….is either “shut down” by a shorted sensor or this is an indication that the PCM will need replacing.

Try unplugging the cam sensor. This is located on the passenger end of the front cylinder head. Crank the engine over for a minimum of 10 seconds with the cam sensor unplugged. I’m looking to see if the engine will start this way…….that is why you need to crank it so long.

P1684 CHRYSLER – Battery Power To Module Disconnected

Possible causes

  • Battery was recently disconnected
  • Transmission Control Module (TCM) was replaced or disconnected
  • Faulty Transmission Control Module (TCM)
  • Transmission Control Module (TCM) harness is open or shorted
  • Transmission Control Module (TCM) circuit poor electrical connection

Malfunction Indicator Lamp, Diagnosis & Testing

The Malfunction Indicator Lamp (MIL) is located on Instrument Panel Cluster (IPC). The MIL informs driver that an emission system fault has occurred and that engine control system requires service. The Engine Control Module (ECM) monitors MIL control circuit for conditions that are incorrect for commanded state of MIL. For example, a failure condition exists if ECM detects low voltage when MIL is commanded OFF, or high voltage when MIL is commanded ON.

Any MIL requesting DTCs that may be set should be diagnosed first.

1. Understand and validate customer concern. Inspect visible system components for obvious damage or conditions that may cause concern.

2. Inspect for related bulletins, recall/field actions and preliminary information.

3. Verify symptom is not exclusively a mechanical concern.

4. Connect a suitably programmed scan tool, perform Vehicle DTC Information function and verify at least one control module communicates with scan tool.

5. Verify there are no control module Internal hardware performance DTCs set.

6. Ignition ON, command MIL ON and OFF with scan tool. MIL should turn ON and OFF as commanded.

7. Ignition ON, command MIL ON and OFF with a scan tool while observing following control circuit status parameters:

a. MIL control circuit low voltage test status.

b. MIL control circuit open test status.

c. MIL control circuit high voltage test status.

d. Each parameter should toggle between OK and Not Run or Not Run and OK.

8. Ignition OFF, disconnect MIL electrical harness connectors. Ignition ON, MIL should not illuminate. If MIL is illuminated, test MIL control circuit terminal for a short to ground. If circuit tests normal, replace cluster.

9. Ignition ON, connect a 3A fused jumper wire between MIL control circuit terminal and ground. MIL should illuminate. If MIL does not illuminate, test MIL control circuit for a short to voltage, or an open/high resistance. If circuit tests normal, replace MIL bulb.

10. If all circuits/connections test normal, replace ECM.

Powertrain Control Module (PCM) 1999-2007

Anytime the PCM is replaced the VIN and vehicle mileage must be programmed into the new PCM. If the PCM is not programmed, Diagnostic Trouble Codes (DTCs) will set. To program the PCM, connect a DRB or suitably programmed scan tool to the Data Link Connector (DLC) and follow scan tool manufacturers instructions. On models equipped with the Sentry Key Immobilizer System (SKIS), program secret key as follows:

If the PCM and the SKIM are replaced at the same time, all vehicle keys will need to be replaced and programmed to the new SKIM.

  1. Turn ignition switch on and place transmission in park/neutral.
  2. Use scan tool and select THEFT ALARM, SKIM then MISCELLANEOUS.
  3. Select PCM REPLACED (GAS ENGINE).
  4. Program vehicle four digit PIN into SKIM.
  5. Select COUNTRY CODE and enter correct country.
  6. Be sure to enter correct country code. If incorrect country code is programmed into SKIM, SKIM must be replaced.
  7. Select YES to update VIN (the SKIM will learn the VIN from the PCM).
  8. Press ENTER to transfer secret key (PCM will send secret key to SKIM).
  9. Program ignition keys to SKIM.

ABS light keeps coming on and then off


ABS Light On

Generally speaking this has to do with the wheel speed sensors going out. They are mounted inside the wheel hub bearings.

2005-chrysler-pacifica-speed-sensor

View of the front speed sensor mounting screw (1), hub and bearing (2), routing clip (3) and front wheel speed sensor (4)

“The 05 and 06 models have a lot of issues with the wheel speed sensors for the abs system. A failing sensor will cause the symptoms that you are describing.
Because of excessively high failure rates, Chrysler has re-designed the sensors and for this reason it is necessary to replace all 4 sensors…………even if just one is bad.” Source: Chrysler Mechanic

Anti-Lock Brake System, Inspection

A visual inspection must always be performed to confirm the presence of aftermarket components, potential collision damage, or areas of concern.

The ABS module is self monitoring. The module will carry out a preliminary electrical inspection of the hydraulic pump motor by turning the pump ON for approximately 1/2 second either when the ignition switch is turned to the RUN position and the brake pedal is not pressed or when the vehicle is in motion and at vehicle speeds above 12 mph. The ABS module will also carry out a wheel speed sensor self-test by sending a reference voltage to all of the wheel speed sensors through their circuitry when the ignition switch is turned to the RUN position, with or without brake pedal application. If a fault is detected in the pump or wheel speed sensors, the ABS module will shut down and disable the anti-lock system. Normal power assisted braking, however, remains.

  1. Verify stop lamps operate correctly by applying and releasing brake pedal with ignition switch in OFF position.
  2. Verify that PRNDL operates correctly on instrument cluster.
  3. Visually inspect for obvious signs of mechanical or electrical damage.
  4. If an obvious cause for an observed or reported concern is found, correct cause if possible before proceeding.
  5. Connect a suitably programmed scan tool to vehicle DLC.
  6. Carry out network test.
  7. Clear continuous DTCs and carry out self-test diagnostics for ABS

Engine light stays on. Mechanic’s scope indicated a code and changed the Catalytic Converter and one Oxygen Sensor. Shortly after the engine light came on again. He changed the second Oxygen Sensor. Light came on again Both times he used his meter, the code said the problem was with the Sensor. Any suggestions for what I should check next? Could the problem be electrical (a short or faulty wire harness)?


I am guessing as to what the actual code is as you did not provide it. If the code is different please indicate it by responding in the comments.

Chrysler Code P0420

Description: Catalyst System Efficiency Below Threshold Bank 1

Probable Causes:

  1. Sensor or solenoid faulty
  2. Connector terminal contact is damaged or corroded
  3. Wire harness – Check harness for correct voltage, open, short to ground or short to voltage
  4. Update control unit software – Check for the latest control unit update
  5. Powertrain or Engine Control Module faulty
  6. HO2S sensor contamination/damaged
  7. Exhaust leaks or restrictions
  8. Catalytic converter damage
  9. Catalytic converter improper operation

No transmission oil dipstick Chrysler Town and Country

Chrysler Town and Country

I am wanting to check my transmission fluid level and possibly change the fluid and filter but am unable to locate the dipstick or fill port. The engine is a 3.6 liter and the transmission is the 41TE type.  Any advise… TKs..


No transmission oil dipstick

I only show this model coming with a 62TE transmission. Must use Mopar Automatic Transmission Fluid Plus 4 or equivalent. Will require 5.50 qts for service.

Your vehicle does not have a dipstick installed from the factory. A special tool is used to check the transmission fluid level. The transmission Oil Dipstick (special tool #9336A, Dipstick) has indicator marks every 10 mm. I have double checked to make sure this one will fit your 2012 Chrysler Town And Country. Comes complete with instructions.

FLUID CONDITION

Along with fluid level, it is important to check the condition of the fluid. When the fluid smells burned, and is contaminated with metal or friction material particles, a complete transaxle recondition is probably required. Be sure to examine the fluid on the dipstick closely. If there is any doubt about its condition, drain out a sample for a double check.

MOPAR® ATF+4 (Automatic Transmission Fluid) when new is red in color. The ATF is dyed red so it can be identified from other fluids used in the vehicle such as engine oil or antifreeze. The red color is not permanent and is not an indicator of fluid condition. As the vehicle is driven, the ATF will begin to look darker in color and may eventually become brown. This is normal. ATF+4 also has a unique odor that may change with age. Consequently, odor and color cannot be used to indicate the fluid condition or the need for a fluid change.

After the fluid has been checked, seat the dipstick fully to seal out water and dirt.
