I had mine flushed at the stealership at 30,000(on my 06' XE CC). I mainly did it because it was given to me by the stealership for free because they screwed up on another service. I sold the truck with 36,000 on it and got a 08.5 SE CC, but didn't have problems with the trans before selling it. Normally I'm not big on these type of things or I try to do them myself, but apparently the stealership actually has a machine to vacuum all the fluid out and replace it. Apparently you don't get all the old fluid out by just draining it yourself. I will probably do it on the 08.5 just so the stealership doesnt give me a hard time if I need warranty work done after the 36,000 mile warranty. After that I'll probably wait a long time till I do it again. You can do a search and see what other guys do about this and there's some threads that talk about what guys here have paid for the service as well. Good Luck
