I would consider 103 to be on the high end of normal. 110 is definitely hot for ATF. There is a thermostat that regulates the fluid flowing in the cooler which could be an issue. But you're low mileage so I would be shocked that it failed already.

 

Thanks a lot for your reply, I will check this also as my car was exported from US to my country with damage so this sensor could be Brocken or malfunctioning. any idea of how its looks like?

 

Hello, I will really be glade to have some advice here, I bough my Jeep 2018 last month only, my transmission oil temperate reached 103C after 30 minutes of normal city driving and some time it reaches 110C, is this normal for the ZF 8 gear/ btw I'm living in middle east hence the climate in my country little bit hot.

Dears, today i reached 125 temperature and for this I'm very worried, please help

 

That is high but not destructive to your transmission. Have the dealer check the transmission cooling sensors.

 

Normal range 175-212 degrees F
Danger zone is about 248 degrees F

Normal range 80 to 100 degrees C
Danger zone is about 120 degrees C

It looks like you are in Iraq? Where in Iraq? Kuwait is the highest temperatures I have ever experienced in my life, so SE Iraq might be temps well above a normally equipped vehicle can handle.

What was the ambient temp, outside air temp, when you hit these temperatures?

If it was the 53°C (127°F) I experienced in Kuwait, I could see that being behind you hitting 125°C on your transmission. Take a drive in the cooler evening and see if you get transmission temperatures out of the normal zone.

See where I'm going with this, in the cooler evening if the trans temps are fine, it may be a case of cooling being inadequate, if the temps are out of range in the cooler evening air temps, than you may have a malfunction behind the high temps.

Like mentioned before, there is a thermostat that cuts out the trans fluid from the cooler when its too cool. That is one thing to look at, if its broken, you might not be getting all the fluid to the cooler and making it run hot.

So its was built as a U.S. Model and then shipped to Iraq (or your country) or do you mean its an Export model, actually built and intended to be sold in the Mid-East?

Cause if it was built with the intent to be used in the U.S. it may have inadequate cooling for the Mid-East.

You may need to add more transmission cooling, if you can find out what WK2's destined for the Mid-East come equipped with for cooling, you might want to get that equipment and retrofit it to your WK2 that was intended to be used in the U.S.

Chrysler for some reason for the last 20 years has gone cheap on the transmission coolers and they have been barely adequate, that doesn't seem to be the case for the WK2, but were using it in the U.S. that has much lower temps than the mid-east, so its not hard to imagine if your WK2 was intended for the U.S. and shipped over to the mid-east, it doesn't have enough trans cooling.

 

Thanks my dears, it was found a problem in the transmission cooling cycle, the pipes were not linked with the transmission so there was no cooling at all. we fixed it now and i'm in testing mode observing the temp. will keep you updated

 

Glad you located the issue👍.
I used our previous 2014 Grand Cherokee EcoDiesel 4x4 to tow a travel trailer in 110/115F temperatures without trans temps going over 205F.
This had the factory tow package with HD brakes and cooling system.
