Well, i know that this question has drowned a few times BUT, I need personal opinions on if I should flush/or drain my tranny fluid on my 1997 Max auto with like 89,900 miles.

I ve heard both good and bad sides but still need help, thanks.

 

Drain and fill only get about 1/2 the fluid out, if not less. Flush does just that, cleans out all the old tranny fluid, including the fluid in the TC, and replaces it with new fluid.

 

ok. so, drainy good--flushy bad.
