JEEP OWNERS ATF+4 Questions

[wn1998]

I am looking to change out the ATF fluid on my 98 Grand Cherokee's 42RE transmission. I would like to replace my fluid with a Synthetic fluid such as Amosil ATF. I have read a few posts on jeep forums saying how if I don't use the mopar +4 I will have problems with my trans.

Also, is the Mopar+4 ATF fluid synthetic? I looked and amsoil atf does meet the chrysler atf+4 spec. However, is it worth paying almost double for amsoil ($9Qt) over the Mopar atf+4 ($4.50qt)?

ATF+4 is semi-synthetic. IN chrysler vehicles, that rrequre ATF+3 or ATF+4, its highly advised, to stay with manufacturer recomendations. Ive chatted with people, who have neons, like me, that have converted too mobil and amsoil ATF, redline ATF, ATF+3 to 4, (4 is okay to use in place of atf+3), and all had said nothing about neagative sideeffects. However, neon mechnics had adviosed they should have styaed with maufacturer fluid recomendations, because some of the multi_ATF fluids, did not list chrysler on the bottle, and also as a jsut in case thing.

I did find on the amsoil site that their ATF meets the chrysler atf+4 specs. Does that mean this would be a better choice for my trans?

The approved ATF+4 formulations are the only ones that have been tested and approved by DC to assure 100% compatibility with your transmission and a minimum level of performance. This is not to say that Amsoil's product is not capable of the same performance and the same compatibility, but it just hasn't been tested by DC.

Amsoil's product may very well be better. I don't know. But how much better? Enough to justify $8.00/qt versus $3.00/qt for SuperTech ATF+4? Not in my book.

BTW...ATF+4 is Group III. Also, many transmission shops that I know of merely use bulk Dexron III + Lubegard HFM in the DC transmissions they rebuild. It's no big secret that this mix doesn't even come close to meeting the long-term fluid durability (and cold temp requirements) of the factory ATF+4 fluid, but the transmissions that are running this mix aren't having issues either.

One of the stipulations in the Chrysler specification is that in order to meet the specification requirements "fluids will contain 6.0 vol%minimum of Lubrizol LZ-3300A Detergent/Dispersant Inhibitor System and shall contain Lubrizol LZ-7720C shear stable viscosity index improver and shall be dyed red"
Can someone from Amsoil confirm that this basic requirement of the Chrysler specification is met by their fluid?

I think they got the "dyed red" part down cold.

Look at Redline C+ ATF, which is recommended by them for ATF+4 applications.

I actually don't know who's additive package Amsoil uses in their ATF, but you can be assured there is more than enough "Detergent/Dispersant" for extended drains - way beyond Chrysler's recommendation. And even better, Amsoil doesn't even use any viscosity index improver - because it doesn't need it! So despite G-man wise cracks, Amsoil is a better fluid.

Did you just fall off the turnip truck?

Nah.
