Ive got a jap import auto box.and it has a button at..with one setting power and one setting hold,what do these do as ive always driven with button in middle,As you can tell i know jack about auto boxes.haha

it makes the gear change alot higher up in the rpm range ... in case your going up a hill and it keeps in out of 3rd/4th or alike u will keep it in the gear to what ever its in

So would it make it accelerate quicker in power mode,ive also been told not to drive round town etc in overdrive

sorry got a little mixed up

 

Hold will stop it from Changing gear under harder loads

Power will Make the Gear changes Higher up the RPM Band

 

No Power gains as such but nice to make it change gear later if your doing spirited runs :)

I haven't taken my Zed lot of overdrive since I got it..... Is that a bad thing then?

If you floor it, it will automatically go into power mode and not taking it out of overdrive is fine, i used to use it in or out when going up a hill as it didnt drop down a gear quick enough.

I always leave mine in overdrive and its been fine

I mostlyeave it in, do drop it out sometimes when u need a quick over take or something :)

"hold" it pulls away in 2nd gear..."power" it pulls away in 1st gear and also changes the shift points higher up the rpm range..."middle" it does nothing except takes orders from its last fixed position either hold or power.
