Question about 1997 Chrysler Town & Country

97 T+C Speed sensor Throttle Position Sensor or Replace Tranny

I went to the place that I usually use due to this problem: While driving the speed slows like I put it in Neutral and once it gets to about 30 mph it jerks and then drives fine for about 2 or 3 miles and then does it again. Sometimes it slows to complete stop. I experienced what seems like exact same problem in my car and after the TPS was changed everything is fine. The mechanic computer diagnostic checked it and said it was speed sensor and solenoid of Transmission but that I needed new transmission or rebuild. The codes were 54 and 57. Same facility initially misdiagnosed the Throttle Position Sensor and flushed the transmission in the car.

    They want to replace the transmission at almost $3500.00 and didn't even offer rebuild as a solution. They seem certain that it is not the Throttle Position Sensor. As far as I know, this is the original transmission that came in the van. But I bought the Speed control sensor that they said was not working and even managed to get a drawing of the engine and locations of all the sensors. The one I bought doesn't even look like any of the sensors that are in it. We traced down every one listed on the drawing and the one we bought has 3 wires and the location of the one we think it was supposed to replace, is close to the same shape but has 8 wires coming off of it. In that case, I don't know, since I've only owned the van for a few years but when they have ever worked on it before this they never mentioned getting any clue that engine or transmission had ever been changed. I called another place and they said that for $1395 they will take it out rebuild it and put it back in. This sounds better than the other price but it is also the difference between new and rebuilt and a lifetime warranty or a 12 month one.

These are trans codes for spd sensor and gear ratio sensors. has this trans been replaces at any time?
For some reason there are a number of different transmissions that have gone into these vans and have different gear ratios. alot of trans shops put the wrong on in that does fit but improper gear ratios. or just hopfully the sensor did go bad. they usually recommend rebuild due to being half in the trans any ways.

umm i dont know what your asking except if this may need a rebuild? I would say ask whats all included in a rebuild. all trans shops seem to differ in what they call a rebuild but all seem, to have about that same price. these chrysler transmission also seem to have alot of random pressure solenoid and solenoid pack and valve body problems.
if you want shoot back a response in what they all do and ill give you my opinion on if its a fair price for what is begine replaced. get written on paper what is replaced. not verbal.
Good luck

What do I need to do with the code p2106


P2106 - Throttle Actuator Control System - Forced Limited Power

Engine power and RPM's will be limited and cruise control will be disabled due to a throttle fault. This occurs when one or more throttle positions sensor readings are out of range or do not agree with each other. Sometimes this code is also set if the throttle plate cannot return to the idle position due to carbon buildup in the throttle body (you might try cleaning it). The code can also be caused by a bad mass air flow, output shaft speed, turbine speed sensor, or crank position sensor. If the throttle body is clean, operates smoothly, and no other sensors are failed, then you might have to just replace the throttle body.

2002 Nissan maxima stuck in 3rd gear, auto tranny . I was driving the other day to realize the light on the dash said I was in 3rd instead of drive, but my gear shifter was in the drive position ....


Most modern day autos are all electronically controlled, Usually if it detects a fault it can go into limp mode which by default is 3rd gear. The fact your speedo is not working which too is most likely sensor driven then that may be a clue to what is wrong. No speed sensor, no speedo and the transmission control unit is not getting the vehicle speed sense either. So it has no way of knowing what gear to be in or any shift points. I'm thinking it's a sensor issue would be my best guess.

91 cherokee shifts fine at fist but after a minute or so it wont shift out of first gear. changed the output speed sensor but no change


Sounds like a bad out speed sensor.Are you sure you replaced the correct sensor?This trans(AW340)Has an output speed sensor and a vehicle speed sensor.The output speed sensor is located on the side of tail housing just next to where it bolts to transmission case.The vehicle speed sensor will be about midway of the tail housing or on the transfer case tail housing on the 4x4 models.It may be a good idea to have a tranny shop you trust run a diagnostic and see if you are getting output sensor signal to TCM( transmission control module behind glove box)and take a look at TPS (throttle position sensor)signal when it is hot to make sure you replace the correct part.I have seen bad TPS sensors on these jeep not affect engine drivability because the sensor is really two(one for trans and one for engine)thus the two plugs on the TPS sensor for the automatic Cherokee.Good Luck and let me know if I can help.

What are the steps to replace the speed sensor? Do I access it from above or below.


Speed Sensor Removal
  • Use the Phillips screwdriver to loosen the screw in the intake boot clamp at the throttle body. Slide the intake boot off the throttle body. Pull the other end of the intake boot off the air filter housing.
  • Locate the Accord speed sensor at the top of the back side of the transmission, close to the firewall. It has two 10-mm bolts holding it in, and an electrical connector at the top. Unplug the electrical connector by squeezing the clip at the top and sliding it off the speed sensor.
  • Use the ratchet, extension and 10-mm socket to remove the two bolts located on the sides of the speed sensor.
  • Remove the speed sensor by pulling on it. You may have to twist it back and forth to work it free. If the drive link does not come out with the speed sensor, remove it from the transmission. The drive link is a very small part that links the speed sensor with the transmission.
  • Speed Sensor Installation
  • Insert the drive link into the new speed sensor. Carefully place the speed sensor onto the transmission, making sure that the drive link lines up in the shaft.
  • Install the two 10-mm bolts and tighten them until they are snug.
  • Slide the electrical connector back onto the speed sensor until it clicks into place.
  • Reinstall the intake boot by sliding it over the throttle body and air filter housing. Tighten the Phillips screw in the clamp at the throttle body.
  • Start the Accord and test drive it to verify that the speedometer is working properly.

    There are two speed sensors. One is on the tranny under the throttle bosy and one is under the tranny.

    This is the one under the throttle body

    This is the one under the tranny near the right wheel.The Countershaft speed sensor is the best bet. i replaced this one on a 1995 honda accord with flashing d4 and after replacement it was gone.the part will be about 125 bucks.

    Need to find out what color the vss wire is under hood


    you don't have a vehicle speed sensor (VSS). You have a wheel speed sensor that tells the PCM vehcile speed in place of the VSS. What are you tring to do?
    ------------------------------------------------------------------------------------
    The electronic engine controls consist of the following:
    • powertrain control module (PCM) (12A650)
    • throttle position sensor
    • idle air control valve
    • camshaft position sensor
    • crankshaft position sensor
    • mass air flow sensor
    • intake air temperature sensor
    • heated oxygen sensor—front
    • heated oxygen sensor—rear
    • knock sensor
    • cylinder head temperature (CHT) sensor
    • power steering pressure (PSP) switch
    • Wheel speed sensor
    The powertrain control module needs the following inputs to calibrate the engine properly:
    • camshaft position
    • engine rpm
    • engine coolant temperature
    • amount of engine detonat
