If its a manual, it's a ZF-6, if an auto, its the 4R100.

Auto tranny is the 4r100 overdrive transmission.

Manual 6 speed is the ZF-6 I believe.

I think there's a how to in the tech articles on the site for changing the tranny fluid - I know there's a good description somewhere around here. Your '02 doesn't have a TC drain - so it's not quite as easy as drain and re-fill - there's a little process you gotta do to get all the fluid out. I just did mine not long ago - not a bad job really. As for the tranny cooler - I believe quite a few guys around here are running aftermarket/bigger coolers - the stock one is marginal.

I'm a firm believer in doing 30K mi tranny flushes (20K mi under heavy towing), with a good ATF. I try to use Motorcraft if I can.

Synthetics really do have some advantages in a tranny that sees some heavy duty abuse, Mobil 1 synthetic ATF comes to mind.

With 88K mi on your rig, I'd put a new tranny filter in as well.

ATF flushes are the surest way towards a long life transmission.
