I have an 05 TSX with about 44k on it ! so being about 6 years old I decided to change the ATF fluid and I think whoever at the factory put on the drain plug had to be a gorilla ! The only way I could loosen that " nut " was with a 2 foot breaker bar & my sledge hammer. Once it was loose very easy, a few metal shavings on the magnetic drain plug but everything else was pretty straight forward. I did torque the drain plug to 36 ftlbs. I took the car out for a ride & I can feel the difference already, not bad for around $29, 3 qts of the Honda ATF fluid, crush washer and cursing the original technician who put it on in the first place.
