Re: 2004 WJ 4.0 trans/ATF level questions
I had no idea that ATF expanded so much over a limited temperature range,
that chart came a surprise. You should really change your fluid every couple years, it would be best to change the filter too. If you add a drain plug in the pan (a few dollars at any auto parts store) ATF changes become as easy as motor oil changes. You can also snake a very thin tube down the dipstick hole and siphon the fluid, you can usually get 4-6 quarts by this method. Be sure to use ATF+4 ONLY, never a 'universal' fluid or an additive to make some other brand the same as ATF+4 (they don't). It is available in Mopar and Valvoline brands at your local auto parts store.
