Have a intermittent but frequent P0741 code. Already

Customer Question

Have a intermittent but frequent P0741 code. Already replaced torque converter lock up solenoid with no change. Torque converter appears to be working as RPM and acceleration is fine with no weird noises. If the trouble code populates its only after driving for 30 minutes or more. Sometimes the code does not populate at all. Fluid is new and at the proper level. New transmission filter as well. However, just before the transmission will throw the code the engine loses power and slowly decelerates. After a second or two it will "wake up" drop down a gear or two, then find the proper gear and resume cruising, but RPMs will be higher now and the code populates. So far I've only noticed this behavior on hills. I lived in Arizona before and only flat ground so if the issue was present did not manifest.

9 times out of 10 this is usually the torque converter itself, but let check a few things out first when I get home from work in about 30 minutes. I will get back to you asap.

You are welcome!

I did not see any bulletins regarding this torque converter code, and like I mentioned earlier, it is almost always a failing torque converter. I have put together the diagnostic procedure for this code in the link below. Click on the link and look at the procedure. Hopefully this will shed some light on this code, and help you diagnose it.

Ya I've seen that before, however I don't have scan tool equipment capable of reading diagnostic data like that. Can you point me in the direction of the proper part number for a replacement torque converter?
Expert:  Chris replied 2 months ago.

Sure. Give me a few minutes to look it up.

Expert:  Chris replied 2 months ago.

Please send me the Jeep's VIN number. There are 2 different possible torque converters, and I want to be sure to get the correct number for you.

I did thank you. Prices aren't too bad. A side question. Since I just changed the trans fluid can I remove the converter without having to drain the transmission?
Expert:  Chris replied 2 months ago.
