Macky,
Yep, dalawa ang overdrive gears mo if that is the case. Pero pansin ko lang, most O/D off switches only cancel top gear. Ganun din ba sa MDX?

kiper,
O/D on mo parin. Ako kahit city driving umaabot ng 5th gear. For special circumstances lang ang O/D off. Kaya nga may warning lamp to inform you that it is off.
