    My OBD2 is giving me P1744 code which tells me the Torque Converter Solenoid is showing a problem with the circuit performance - whatever that means. Interesting, because I have the same problem as I had before only now I have put in a new valve body which should have a new torque converter solenoid. I don't know where to go from here.

    Hi,



    I'm not sure what the tcm is. Is it the the pcm power control module? Is the pcm housed in the valve body?

  • dgardner459 May 11, 2010

    I finally took it in. It appears that there is a mechanical problem in the torque converter. Thanks

You may have a pressure sensor not working,have the codes read by a code reader,to make sure.

    Then it is most likely the tcm transmission control solenoid

    Have you had the codes read?This needs to be done to ensure the correct procedure is followed,auto zone can do this for you for free,then,this will narrow the search down to a area,and it is most likely a sensor on the transmission.

1st let me explain that this transmission is controlled by a computer called the PCM, (Powertrain Control Module) when the PCM senses a problem in the way the electronic controls are functioning that control the transmission it then turns on the check engine light and set a fault code in its memory for the area or component that causing the problem, the 1st step to fixing this is having the PCM tested for the fault codes that it has stored in memory, this is called an "OBD2" fault code test, once we have the fault code we can see what is causing the light to come on and most likely causing the transmission to act up, so get the test run, any Aamco transmission repair shop will do this test for free are well as do a road test to give u some idea of the cost to repair the problem, so get the car tested ASAP. This advice is based on my 35 years as a factory trained Ford dealer service technician.

2002 chevy s10 temperature gauge jumping around, feels like automatic transmission slipping at speeds above 60 mph


Do you have an OBDII scanner to check the real temperature? Want to make sure it's not overheating. If it's normal, could be your temperature sensor starting to go out, or ignition switch. Any check engine lights? If so, get the code for me, can go from there. At a constant speed, you sure it wasn't a misfire instead? Check your trans fluid, make sure it's full. I was just in Tahoe, pretty sad not much snow at all.

run the fault codes first to check for faulty sensors
what you describe indicates a problem in the exhaust in that when the exhaust gas volume reaches a certain level the sensors are reporting it and the ECM is not able to fix it
have an accredited exhaust shop check the cat converter
for failure and partially blocking the exhaust at speed
if it was a fuel pump you would run into problems long before the speed at which it occurs
AT best it could be an EVAP problem with the vent not working properly but I think that it is exhaust related

Testing

Check the Manifold Absolute Pressure (MAP) sensor circuit as follows:
Ignition OFF, disconnect the MAP harness connector at the MAP sensor.Ignition OFF, test for less than 5 ohms of resistance between the low reference circuit terminal 2 and ground.If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the ECM.Ignition ON, test for 4.8-5.2 volts between the 5-volt reference circuit terminal 1 and ground.If less than the specified range, test the 5-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the ECM.If greater than the specified range, test the 5-volt reference circuit for a short to voltage. If the circuit tests normal, replace the ECM.Verify the scan tool MAP Sensor parameter is less than 1 kPa.If greater than the specified range, test the signal circuit terminal 3 for a short to voltage. If the circuit tests normal, replace the ECM.Install a 3A fused jumper wire between the signal circuit terminal 3 and the 5-volt reference circuit terminal 1. Verify the scan tool MAP Sensor parameter is greater than 126 kPa.If less than the specified range, test the signal circuit terminal 3 for a short to ground or an open/high resistance. If the circuit tests normal, replace the ECM.If all circuits test normal, test or replace the MAP sensor.

Check the Throttle Position (TP) sensor circuits as follows:
Ignition OFF, disconnect the harness connector at the throttle body.Ignition OFF for 90 seconds, test for less than 5 ohms of resistance between the low reference circuit terminal C and ground.If greater than 5 ohms, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the ECM. Ignition ON, test for 4.8-5.2 volts between 5-volt reference circuit terminal E and ground.If less than 4.8 volts, test 5-volt reference circuit for a short to ground or an open / high resistance. If the circuit tests normal, replace the ECM.If greater than 5.2 volts, test the 5-volt reference circuit for a short to voltage. If the circuit tests normal, replace the ECM. Verify the scan tool TP sensor 1 voltage is less than 0.1 volt.If greater than 0.1 volt, test the signal circuit terminal D for a short to voltage. If the circuit tests normal, replace the ECM. Verify the scan tool TP sensor 2 voltage is greater than 4.8 volts.If less than 4.8 volts, test the signal circuit for a short to ground. If the circuit tests normal, replace the ECM. Install a 3A fused jumper wire between the signal circuit terminal D and the 5-volt reference circuit terminal E of the TP sensor 1. Verify the TP sensor 1 voltage is greater than 4.8 volts.If less than 4.8 volts, test the TP sensor 1 signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the ECM. Install a 3A fused jumper wire between the signal circuit terminal F and the low reference circuit terminal C of the TP sensor 2. Verify that the TP sensor 2 voltage is less than 0.1 voltIf greater than 1.0 volt, test the TP sensor 2 signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the ECM. Ignition OFF for 90 seconds, disconnect the harness connector at the ECM.Test for less than 5 ohms of resistance on all TP sensor circuits between the following terminals:ECM C2 signal circuit terminal 65 to TP terminal DECM C2 signal circuit terminal 63 to TP terminal FECM C2 5-volt reference circuit terminal 3 to terminal E If greater than 5 ohms, repair the affected circuit for open/high resistance.Test for infinite resistance between TP sensor 1 signal circuit terminal D and TP sensor signal circuit terminal F.If less than infinite resistance, repair the short between TP sensor 1 signal circuit and TP sensor 2 signal circuit. If all circuits test normal, replace the throttle body.

Throttle Body Relearn Procedure
NOTE
Do NOT perform this procedure if DTCs are set.

Start and idle the engine in PARK for 3 minutes.With a scan tool, monitor desired and actual RPM.The ECM will start to learn the new idle cells and Desired RPM should start to decrease.Ignition OFF for 60 seconds.Start and idle the engine in PARK for 3 minutes.After the 3 minute run time the engine should be idling normal.
NOTE
During the drive cycle the check engine light may come on with idle speed DTCs. If idle speed codes are set, clear codes so the ECM can continue to learn.

If the engine idle speed has not been learned the vehicle will need to be driven at speeds above 70 km/h (44 mph) with several decelerations and extended idles.
After the drive cycle, the engine should be idling normally.

If the engine idle speed has not been learned, turn OFF the ignition for 60 seconds and repeat step 6.Once the engine speed has returned to normal, clear DTCs.

Hi I have my transmission of mercury mystique 1995 ,it shift from gear 1 to 2 easily and from 2 to 3 easily but when the car speed close to 80 kms/hr it start to shout and the engine speed jump to 4000 RPM...


is your transmission a automatic or standard ? Do you have a check engine light on ? If it is a automatic, was the service you had done a drain and fill or a complete flush, and finally what do you mean it start to shout

I have a 1996 mystique that i just bought. Everything is fine with it, except driving down the road as soon as i hit 60 mph the abs light kicks on and stays on. Turn car off, then poof like a clock soon as...


It could be a bad abs wheel sensor but I am sure that if you have the vehicle scanned for trouble codes it wil help to isolate where the problem is

Tranny drives good for a bit them it shifts hard.


On your transmission there is a transmission speed sensor (vehicle speed sensor). These do go bad sometimes. What happens is you are going along all happy at 60 mph but the info being transmitted by the sensor is incorrect and BAM you're not so happy anymore. This also puts a lot of additional wear and tear on the transmission. For this vehicle at Autozone you can buy the sensor I believe for around $40 and it is not that hard to change or maybe expect to pay maybe $40-60 to change (guesstimate)...hope this helps you.

97 concorde with 3.5 engine @ 40 to 45 mph it starts bucking .


Computer firmware needs upgrade

Take your car to a Chrysler dealer shop and have them update the transmission program.As your tranny wears it loses it shift point and stutters between 40 - 45 mph looking for the right gear to change to..Had same problem in 94 Concorde and 94 T&C minivan.Reprogramming tranny fixed both cars.

one unit that operates ratio changes and is connected to the engine is that vacuum operated actuator on the transmission
it is possible that that unit is failing , vacuum hose is leaking and that will cause ratio changes as the vacuum varies
run the fault codes to check for wiring problems or VSS or TCM problems as well
