2004 WJ transmission

Recommended Posts

So My wife and I own our first vehicle built in the new millennium. Haha anyway it's a 2004 WJ Grand Cherokee. 4.0, 242 transfer case. I have no idea though what transmission is in it, it's between a 42RE, or RLE or something like that. I figured one of you guys would know. Whatever it is it's safe to assume it should have ATF+4 in it as well?

 

Thanks for any help and info.

4.0 has the 42re. Sometimes the dipstick list what to use but yes it is the ATF+4. 

 

As a side note. I would do a service and replace the filter on it if you haven't. Those aren't the greatest trannies and life expectancy is really hit and miss. My dad's WJ crapped out at 150k, my wifes KJ has 180 and is still going but the tranny is really sluggish. Around 130k we serviced it because it had the shudder problem (felt like you where driving over cattle guards) but the shift points drive me insane. 

 

Another thought is putting one of these in. They help with a lot of the shift issues.

Thanks! I am doing a service today, at 186k miles everything works and shifts great but the fluid isn't the cleanest so I figured it would be a good idea to change it.
