Some of the 'sst specialty shops' recommend changing your sst fluid @ 5k to remove initial break-in crap and then 10-15k if you have fun while driving..20-30k otherwise I think.

An extra oil change for only a couple hundred bucks (if you diy) is worth the life/safety of a 10k tranny imho.

 

I'm pretty sure the dealer changed my SST fluid at my 30k service.
