2008 Fit Sport with 165k. Runs great except 5th gear (automatic). In 1st-4th it is fine at idle, cruising speed and under normal and hard acceleration. In 5th it is fine cruising, but above 60 it does mild lugging under acceleration. Thoughts?

 

When was the ATF last replaced?

 

Full tune-up in September, but don't know if the ATF was replaced or topped up. Good place to look.

 

Yesterday the check engine light cam on and she threw off misfire codes. Replaced the coils (OEM) and she now runs fine.
