The 630V transmission takes 4.2 quarts. In 2001, they recommended Dexron for that transmission, in 2003 and later they recommended 15W40. Same transmission, but the heavier oil recommendation was due to rattling of the tranny at idle speeds. You could use either, but unless you're annoyed by transmission noise, I'd just refill it with the same stuff that comes out - Dexron (red) or 15W40 (oil). I've never pulled my transmission cooler, but it looks to be a couple of bolts on the bracket, the two 1 1/4 water hoses, and the two oil lines. Make sure you seal the oil lines when you reinstall.

Thanks Bigmac. When I called the dealer on these questions they could not give me a straight answer.
