DISCUSSION:

ATF+4(R) - (Type 9602) is being used as factory fill for Chrysler Group automatic transmissions. ATF+4(R) is recommended for all vehicles equipped with Chrysler Group automatic transmissions EXCEPT FOR THOSE LISTED IN THE NOTE ABOVE.
NOTE :ATF+4(R) must always be used in vehicles that were originally filled with ATF+4(R). DO NOT USE ANY OTHER FLUID.

NOTE :ATF+4(R) is backward compatible with ATF+3, ATF+2, and ATF+. Additionally, ATF+4(R) can be used to top off vehicles that used ATF+3, ATF+2, or ATF+.

NOTE :If ATF+4® is used to service models originally filled with ATF+3, ATF+2, and ATF+ the fluid maintenance schedules listed for that model does not change. The service interval currently in effect for a given model should continue to be followed. Refer to the Service or Owners manual for maintenance schedule directions.

In general terms, If ATF+, ATF+2 or ATF+3 was the recommended fluid, it is now recommended to use ATF+4®

BENEFITS
^ Better anti-wear properties
^ Improved rust/corrosion prevention
^ Controls oxidation
^ Eliminates deposits
^ Controls friction
^ Retains anti-foaming properties
^ Superior properties for low temperature operation

FLUID COLOR

Mopar ATF+4(R) has exceptional durability. However, the red dye used in ATF+4(R) is not permanent; as the fluid ages it may become darker or appear brown in color. ATF+4(R) also has a unique odor that may change with age. With ATF+4(R) fluid, color and odor are no longer indicators of fluid condition and do not necessarily support a fluid change.

Dex/Merc!!!!!

Thanks Tim, does it matter if I get II vs III vs V ? etc?

[Krome]

wouldn't be a bad idea to change the filter. atf +4 is apparently a better fluid, but originally the trans was designed for dex II or III I believe.

[Mitch]

I guess I will do the NP231 TC while I am at it... same fluid or ATF-4 - seeing mixed results on this too.

[jason m]

Mitch check the dip stick tube and see what it says on there. My 99 XJ DD I only run ATF+4, most Mopar tranney need the ATF+4.
My dip stick say on it ATF+4.

Jason.

[Krome]

no need for friction additive for rear end with a mini-spool/ I never used it and there is no purpose, it's for clutches. Same with the front, just regular oil.

Just buy a bunch of atf+4 and put it in your transfercase and trans. Both can take cheaper atf however, but since jeep issued that TSB I would use the +4

[Twisty]

Just put dex/merc in everything.  Go on NAXJA or JeepForum and see what people are putting in their AW4s.  90% are dex/merc.  The AW4 is a Japanese transmission...so keep it happy with dex/merc.

No additive for the diffs.  Additive is for limited slips. 

[Mitch]

just got a case of this:

http://www.valvoline.com/products/consumer-products/automatic-transmission-products/automatic-transmission-fluid/33

off amazon for 29 dollars shipped to my door. It was an "open box" deal. Reg price was 56. Autozone was 40 at the cheap. I dont know how it works, appears to not be dexron III or whatever, but the spec sheet looks like it will work.

Did I F up?

[Bluerocket]

I'm no expert, but I think the AW4 I used to use Dextron 3.

The site says:
Helps provide smooth shift performance where DEXRON®-III or a MERCON® fluid is specified

So I think Its good?

[XJFever]

I'm so confused now, was trying to watch this so I know what to put in my aw4 and diffs.

[jeeptech]

ATF+4 is a very good fluid and will work in all chrysler trans applications including the AW4.  I have fixed trans shifting issues with just an ATF+4 fluid change.  ATF+4 has the same friction modifier in it that is used in Limited slips this will help the clutches hold better and last longer.  Go with ATF+4.

[Mitch]

So, should I return my purchase Chris?

[Mitch]

Installed these last night. Now I can hear over the hum on the highway! Only two of the 4 original speakers were working and they were both blown.

These have terrific highs, and at an upgraded size of 6.5" I was hoping for a little more bass.... lol NO BASS! Will be looking for a little sub/amp setup in the future.
