I read where they say you should have your tanny flushed at 50K miles...well mine will be hitting that mark soon!!! I have heard from some people that if its not broke don't fix it..as in DONT DO IT! Until I feel as if it truly needs it! So what would you guys suggest to do? Also I was told that I wont need to change my filter until around 100K and that some of the newer cars don't have a "filter" more like a screen and it gets flushed when they flush the tranny.
