Atf-4

[MLee]

Is this another Dodge exclusive??? or is it available at the part stores. Can't seam to locate it in my area. (Salt Lake City) Checker, Auto Zone don't have it. Maybe Napa???checked the valvoline site and they do not list ATF-4. Is the #4 synthetic? What is the difference between the #3 #5

thanks all for your help.

ATF+4

ATF+4 D/C ONLY. The other synthetics will work but it is not the same, D/C may denied warranty on trans if any other type of fluid is found.

MLee,

Find an Amsoil source, and they will have ATF+4. The Amsoil brand is a FULL synthetic.

You could call a trans rebuilder like DTT and ask them. Their answer would be to run the Dexron III Mercon fluid though. The ATF +3/+4 is basically the same as the Dexron III Mercon, but has "friction modifiers" in it. These allow for more slippage so that you get a nice smooth shift... which also means the most wear that can happen is happening.



If you used the Dexron III Mercon and found the shifts too harsh (which I doubt you will), you could always add the additive that basically takes it up to the level of the +3/+4. It's kinda like the friction modifier you would put in a posi rear end.

The reason I ask is because the power steering, and transfer case use this oil also. acording to owners manual.

For a mere $7~ a quart for the approved Chrysler synthetic ATF+4, why not stop by the dealer for some and keep your warranty happy? FWIW, I had to go to the dealer to buy the truck. Autozone didn't have that either. I don't understand the taboo about the dealership unless you can get approved parts and fluids elsewhere for less.

FYI,

Chrysler ATF +4 is considered a "Moderately slippery" fluid, while Dexron II & III, as well as MERCON V is considered a "Slippery" fluid.



Coefficient of friction of a fluid will effect the shifting characteristics of an automatic transmission, therefore it is PRUDENT to utilize an ATF matching the requirements of the transmission manufacturer.

thanks for all your input on this. He is going to the dealer today and ask for the plugs and let them know about how displeased he is with the way his truck was delivered to him. Thanks
