kind of depends...drag race 1/4 mile=OFF
Long High way Inerstate race OFF until the motor feels like it has no more go power then turn on the OD. It's like shifting into 5th gear.
this is an auto we're talking about. this has nothing to do with a 5-speed. 5 spds don't have bands. typically, the OD band can only handle 1/2 as much power as the gears can. that's why there is aftermarket replacements for them.
