Just changed my tranny fluid this weekend... oddly enough the old tranny fluid was just as clean as the stuff I put in.... oh well - at least I know it's changed.

I had the same problem. Owner's manual says take it to the dealer for a tranny fluid change, but all you have to do is go to AutoZone and buy a Suction Pump. It was marked as $34.99, but when I got to the register the dude said "$10.49, sir"... Can't complain.

Anyway, yeah the end is the same size as the hole, but get a friend to pump the ATF while you hold the end of the tube as flush against the overflow drain as you can. I think we drained maybe 4 qts or so from both the tranny AND the transfer case. As for the amount to fill, just keep fillin' til it overflows. Then start up the truck, shift through the gears a bit... get it all "up in 'dere"... turn it off, open the overflow, fill it some more... etc.. until you get in as much as you took out. I plan to go 'down below' again probably this afternoon with a cup and open that overflow just to let anything else that wants to drain drain If i'm not mistaken, you can cause damage if your tranny sump is too full. Only thing that sucks is the fact that you lose a bit of tranny fluid -- no big deal unless like me you paid almost $100 for the ATF case!

While we're on the subject of fluids, i believe there's a drain for the rear diff, but what about the front? seem to recall someone saying the drain is just the lowest bolt?
