also u mentioned gm stuff doesn't seem to last as long. how long?

thanks.

By warmer climate, I mean Southern California-ish. We rarely see 50-something degrees (unless you live in the mountains ofcourse) so the thicker fluid doesn't get too bad/notchy. For you, I would stick with the Redline MTL.

There is a good write-up posted above about the GM stuff. Basically it is smooth as butter when you first put it in but some report that the smooth feeling goes away at or before 10k miles. I like a longer service interval for the tranny fluid (more like 20-30k) and I have found the Redline MTL satisfies that requirement well.
