So Im curious, i plan on changing the transmission filter and transmission pan gasket..
But i know atf +4 is made for jeep and Chrysler products but the stick says dextron 2 (and dextron 3 supersedes dextron 2) and i just so happen to have a gallon of that chilling in the shop....my question is just to be sure would that be ok to run in the jeep.

 

What vehicle year, and transmission model do you have?

 

98 grand Cherokee Laredo...not sure what tranny I have...how can I find out?

 

Just did some research and it looks like most likely a 42RE

 

Is it an auto or manual?

If its auto you should have the AW4 and it uses dextron 3, Chrysler did do a study saying that dextron 4 was safe to use. People have said they switched to the dextron 4 and it caused slipping and other bad things up to complete failure, not saying its all true and there is no hard fact that the dextron 4 was the cause. People also say Chrysler deemed dex 4 safe because they no longer have to warrantee the AW4, again no hard facts that I know of.

If its manual use gear oil don't know what weight sorry.

Edit: oh snaps didn't realize it was grand Cherokee tech. My bad all this info probably doesn't apply to you. Sorry

 

Its auto...not to clutter this thread but I noticed it has gold badges, didnt know if that was of and significance...but its just a basic 98 jeep grand Cherokee Laredo 4.0

 

ATF +4 supersedes all previous recommended transmission fluid for the 42re. http://www.wjjeeps.com/tsb/tsb_wj_2101407.pdf
Has the most current technical service bulletin from MOPAR.

 

Ok well I have a whole gallon of dextron 3 doing nothing in the shop..where as the ATF +4 is 6.99 a quart....im guna go with what I have since I already have it.lol I just wanted to make sure it would be ok to use.lol but thanks for the help!

 

Get yourself a reusable pan gasket from the dealer if you don't already have one. It is way better than the cheap rubber or cork POS the filter kit comes with.

 

My filter from AutoZone came with 2 rubber gaskets

 

If my memory serves me correct, the reason for the two pan gaskets is that the pan changed shape. Only one should match the shape of your pan. Though I do agree with Bustedback go to the stealership and buy a gasket from them.

 

still waiting to hear if the dex 3 is safe for GCL?

 

20 bucks well spent.

 

only 1993 grand cherokees had the aw4, the rest were 42re. 4.0s anyway

 

Like I said I didn't realize it was a GC. I just read the title and what he said.
