Trans Fluid Type 99 Grand Cherokee 4x4

Getting ready to change the trans fluid in my 99 Grand Cherokee 4x4, but don't know what type to use. ATF3? Dextron 3? Looking for regular fluid, not synthetic. Suggestions?

There is only one fluid recommended for the 45RFE transmission behind your 4.7L: Mopar ATF+4 or ATF+4 made by one of the Chrysler approved manufacturers like Valvoline. Using anything else means that you are experimenting with a very expensive piece of machinery.

ATF+3 was designed for pre-99 transmissions and has been superseded by ATF+4.

The AFT+3 is not synthetic. AFT+4 is. ATF+4 cost $ 4.19 to 4.69 per qt for Valoline.

thanks for the quick response guys! Is the ATF +4 safe for the 1999? I saw it wasn't safe for 1999 Dodge minivans, something compatibility with the seals. I know synthetic isn't compatible with some seals and will cause leaks. Takes about 9 quarts for the pan and filters right?

Yeah, the '99 has the same tranny as the other years, so use ATF+4. 9 quarts sounds about right. I lost count when I did mine.

I drained mine overnight and only got 4 ½ qts out of her. I would purchase 6 just to be safe.

You also need a small Torx key/wrench to remove the filter. I cannot remember if it was a T15 or a T25
