Oh deer... I guess I might have to take a loan out in order to buy enoughthanks for the info, I'll definitely keep that in mind. Actually, my dad has been wanting to flush his trans as well (he has an '06 base model) so IF his can also take Dexron III/ doesn't require the 4/5/6 (whichever really is the one available that is newer than 3) maybe we will just buy several of the 4qt jugs together for both of the cars. His trans is definitely overheating though, sometimes getting up to around 220 degrees and shifting hard quite often once it's warm, and that car is at a little over 192k miles. I am a little concerned about a him flushing his trans, though I also haven't found his fluid to be too dark/containing any metallic specks or a burnt odor (yet)... it was overfilled when he bought the car too, air bubbles on the dipstick whenever you'd check it. I feel like he might have a clogged cooling line or just old filter that is causing this (that and the fact that he drives it a LOT, he loves that car, I tell you).
