Hey Scotty hope you are doing well. So I just had my transmission fluid checked on my 06 mustang GT they said it's dirty. How critical is it to get it changed? How long can I go after it's changed before I should change it again? I drive about 7,600 miles a year. Lastly they said I should get new break's and flush the fluid. How critical is that, my breaks are at 2mm I was going to wait a few months.
