Checked the manual and it says that you use "hold" when starting on a road surface that is slippery and/or with snow and the vehicle will start smoothly in second gear....
Position 1 >> Shifting Gear 2
Position 2 >> Shifting Gear 2
Position 3 >> Shifting Gear 3
Position 4 >> Shifting Gear 3
So, shifting is performed only on 2nd and 3rd gears....

its just to hold the gear at a higher RPM than the tranny would usually upshift to. useful when overtaking, on a steep uphill, engine brake on a downslope, or if you generally just want to hold the gear in.
also akin to disengaging overdrive. as OTEP said, no harm done. aside from higher FC that is..

Overdrive is the opposite of underdrive. When one rotation of the driveshaft is equal to one rotation of the wheel, this is called direct drive (gear ratio 1:1). When the gear ratio is less than 1 (e.g. 0.4), then that is overdrive because the wheel will make one complete rotation even if the driveshaft has not completed one.
Overdrive is just making top gear (which is an overdrive gear) accessible or not. It does not affect the other gears in the range nor will it affect the way the tranny shifts. If O/D is off, the tranny will bump against the next highest gear (usually 3rd) and stop upshifting.
This can overheat your transmission and destroy it. Hence, O/D should NEVER be turned off unless in the exceptional cases detailed in your vehicle's owner's manual.

hmm so now im confused.. one of our AT equipped cars doesnt have a dedicated power/ect button so thats why we press the OD button when needed. it doesnt hold the gear till redline, it does shift automatically when im not pressing that hard on the pedal.
example: OD on and light pedal press, the tranny shifts at around 2K-2.2K rpm
OD off and light pedal, will shift around the 3.5k region
now if i press heavy enough on the gas it will stay in gear up till redline regardless whether OD is on or off.

September 21st, 2007 08:01 AM #18Dude, magka-iba ang POWER at ang OD. Magka-baliktad sila. BAsically, kung power ang button mo at gusto mo matulin (pero malakas sa gas) dapat naka-ON. Kung OD naman, kung gusto mo matulin pero malakas sa gas dapat naka-OFF. And vice-versa. So ang "tipid-mode" nila, Power=OFF samantalang kung OD=ON.
