I plan to do this soon, I believe it is about 5-6 quarts. Has anyone done this yet. Thank you.
When I did the flush method I wrote about in the article, I removed pretty much 11-12 qts right on the nose (I had a 5 gal bucket, it had graduated markings so I was able to measure how much I had removed.). The Haynes manual I have states that full capacity, including TC is 11.2qts, and what I've heard on here is 11-13 qts. If you have the small pan, several on here have stated it should be around 9 qts. I am inclined to believe that you will get nearly all of the fluid out of the entire transmission. There will of course be some left, however it's a negligible amount. I'll tell you that when I changed mine at maybe 74,000 miles or so on my 2002...it was nasty. Nearly black fluid and the pan had a layer of black grime on the bottom of it. After I changed the fluid the truck shifted more smoothly (maybe it's psychological, but I swear it did). Keep in mind that there is little to no load on the transmission while it idles in park. I did the change and wrote the How-To based on what I learned from other members here when they did the same thing, and none of them had reported any problems (that I am aware of). If it makes you nervous about doing it, then I would definitely pay someone to do it for ya.Darrel, the guy I work with, says it wont...but I don't know. I've got half of a mind to take it to a shop, and bring them the fluid, the deeper TCI pan, and a shift kit, and say, put all this, on that trailblazer there.
