I've never priced the stuff, how much is it? I know the cheap stuff is like 10-15 a gallon at walmart and the volvo stuff works out to about $60 a gallon.

I've never had to do a tranny flush, I've either been hit and totaled or sold the cars before the fluid gets to that brown stage on every car except the one I'm driving now. I think I'm going to need it soon because its become a deep red as though its going to switch to brown in 5-10k..
