40k miles and a flawless transmission.

 

[Ratbert]

Not only is it reliable, it is also an extremely good transmission as is.

It's not like the manual.

 

[MountainsOcean]

85K Miles not a single issue.

 

[Tyler88]

So far at 60k miles it has been good

 

[YBABRAT]

90k+ on one of the best trannys made in US makes.

 

[Weaselee]

42k and smooth. I have a 42RLE and an E40D to compare to and it’s definitely the smoothest

 

[Speed331]

90k+ without fault. Paired with a 2.0t and it's still zippy as all get out. Changed the fluid and put on the PPE pan a few months back.
Best auto tranny I've ever driven.

Yes….. I also have the same transmission in my ram work truck. Pulls the trailer a couple times a week and there’s always 3-4 hundred pounds of tools in the back under the tonneau cover….has 154K miles on it and I haven’t touched the transmission at all…. Haven’t decided yet if I’m gonna change fluid in the jeep or not….. if I do, it will be at 50K

 

[Stuckinthesand]

90k miles with no issues and 60k on 35"s. Changed fluid at 60k miles and will continue to change at 60k intervals.

 

[shane h.]

69K on mine. 57K on hers. Zero issues. I did the transmission fluid dump & fill three times on each at 50K miles.

Most of the Jeep transmissions are a ZF design but made in the USofA by Stellantis. If you want to know for sure look at the bottom right corner of your window sticker. Here's a copy from my 392:
