i know dis is going to sound stupid. What specificaly
does the (POWER) and (OVERDRIVE) buttons do?
Because i have a fair idea but not accurate enough.
Thanx

the power button give you much more postitive shifts, and also allows higher revs before the auto shifts.

Overdrive is just that. It locks up the torque converted as though it gives you another gear lowering the revs at crusing speeds.
