trans fluid specs

I need to change the trans fluid in my 02. It has a 4.0 and auto. What kind of fluid do I need? And about how much?

Check your Owner Manual. ATF+4 likely. About half (4 quarts) comes out with a pan drop/filter change. The remainder stays in the torque converter.

The nice thing about transmission fluid is that it's (usually) back compatible from model year to model year. I.E. Transmission fluid for a brand new car of a particular make ought to work for a model that is 5 or more years it's senior.

Just grab some bottles of that universal ATF at Checker O'Reilly or something. It'll work.

ATF+4 and Universal stuff aren't the same thing. Use authenic licensed ATF+4 and sleep well knowing you have a long life, synthetic, recommended fluid. Castrol makes it as do several others under license with Chrysler. Available at Walmart. The Universal stuff is more like ATF+3 which isn't the same long life product.

I agree.

If your going to go through the trouble, order the Royal Purple Max ATF from Amazon and get as good as you can. It's compatible and I think goes up to ATF5+ now... Great stuff, I just put it in my 2001 transfer case which calls for ATF4+

No ATF+5 out there yet. I see reference to it every once in awhile, but it doesn't exist.

What Consumers Need to Know About ATF+4: Chrysler LLC ATF+4® Info Center

Licensed ATF+4® Brand Names: Licensed ATF+4® Brands

Using anything that's not licensed is second guessing ie potentially borrowing trouble. No need to go there.

As stated above ATF+4 but dont do just the filter and fluid in the pan. Pull the cooler line hose off and put it into a 5 gal pail. Start eng. and keep adding fluid untill it comes out clean. I did that on my 01 TJ and it took about 5 gallons of fluid to do the job. Start saving your money that much fluid is not cheap.

If you drain, fill, run, drain, fill etc. 5 times, you essentially get over 95% of the old fluid out of the system, using 4X5=20 quarts. Draining is facilitated by installing a drain plug in the oil pan or pumping out through the filler tube.

IMHO it's much wiser to use the recommended fluids, including antifreeze, than the so called universal stuff. It may be a little more expensive but in the long run you'll be better off. OP: owners manuals are good to have and can easily be found on line.
