Transmission Problems
I got a rebuilt transmission put in my 2002 MDX in October last year. As soon as it was put in the mileage went from 19MPG (12L/100km) to 13MPG (18L/100km).
Then in January I needed a new Fuel Pump and the mileage then changed to 17MPG (14L/100km).
Also it still kind of kicks into a lower gear...
