I just looked it up on autozone.com and two results came back. You can use Dextron III/ Mercon or ATF+4. But you can call them to be sure.
This is a very good answer below but it does NOT apply to a 1999 Isuzu Rodeo. The Rodeo's transmission is sealed, you cannot check fluid levels at home, you must take the vehicle to an authorized Isuzu mechanic so they can check the tranny fluid for you. Transmission: Keep an eye on your oil level, as it can get low on you real quick, especially on long hi speed highway trips. There are ways to remedy this. If equipped with an AT, your rodeo has a 4L30E GM trans. You should change the ATF. BMac- for the ATF leak thing, check the accumulator piston cover on the pass side of the trans. VERY common on the 4L30E. Leaks? How about the accumulator cover? It's on the right side and it's round. Check this: Accumulator repair: before trying to remove the snap ring you need to push the accumulator cover in then remove the cover don

The power steering fluid is ATF fluid on BMWs and you can check it from the cap in front of the engine that says ATF fluid only. Take the cap off and on the bottom of the cap you will see a stick, check it there.
