There are a number of reports on this forum that suggest ATF+4 might not be so "fine."

I know that there are very strong feelings about this subject but I'll still have to stand with the engineers. From the 2007 bulletin (NUMBER: 21-014-07

):

BENEFITS

^ Better anti-wear properties

^ Improved rust/corrosion prevention

^ Controls oxidation

^ Eliminates deposits

^ Controls friction

^ Retains anti-foaming properties

^ Superior properties for low temperature operation


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.

Do you have any idea why "the engineers" don't recommend ATF+4 in the XJ models prior to 1989? Is there something special about the pre-1989 AW-4 transmissions? Or did "the engineers" get confused?

I have no idea why they didn't include the '87 and '88 model years...was there a design change in '89...don't know. I do know that they will issue FSB's based on warranty and other dealer repair feedback; maybe that's why they did it...then again there have been some "Black Helicopters" around lately.

I'm done here. I'm changing my power steering pump (from O'Reillys) for the third time in six weeks.

Are you using ATF+4 in your power steering pump? That's what the later model Jeeps use.

If you only drain what is in the pan, it will take between 3-4 quarts to refill. A whole lot more if you're replacing every drop in the transmission, torque converter and pan.

Be darn sure not to overfill when you refill. A little fluid goes a long ways on that dipstick. Final additions should be done with a hot engine, fully exercised transmission, level surface.

IIRC, 3 in the pan and like 8 in the transmission.

EDIT:
The 99 FSM indicates that the approximate refill capacity for the AW-4 is 8.0 liters (16.9 pints), i.e. 8.5 quarts. This would be completely dry including the torque converter.

Drain and fill is usually fine unless you are experiencing systems or unless fluid changes have been ignored....ie: fluid is dark and/or you don't know history of maintenance. Then it's not a bad idea to drop the pan and clean or replace the filter (basically a screen).

Start a new thread. The repair you are asking about is not related to this one. It gets too confusing to stack one type of repair on another.

OKAY, i'm bringing this back to life. I've read the 4 pages and haven't really come to a conclusion. My XJ has 192,000km on it and it looks as if it's been a long time since the last fluid change as it's just about brown. Should I change it out?? Should I leave it? Should I drain the pan and fill it, drive it, drain, fill drive, drain fill drive? I need some serious advice on this topic. It is shifting great right now, but do I want to keep the old crap fluid in there??
