^ Improved rust/corrosion prevention
^ Controls oxidation
^ Eliminates deposits
^ Controls friction

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.

There are several pay websites setup for "shop" type environments. I don't know where that one came from, the skills center on post can pull any that we want for us.

This bulletin is from Chrysler and the manufacture of AW4 dont have any update on this. The 1993 isnt there so i dont think this applay to 1993 GC with AW4. If Chrysler is doing something wrong the AW4 is looooong time over any warranty.

The AW4 was only in the very early 93's ZJ's. It was in no other. It covers the AW4 equipped ZJ's...
