    Hi all,

    Glad to be able to legitimately join, having just taken possession of a VZ Wagon 9C1 spec, plus a few other little bits and pieces.

    In the center console there is button labelled 'PWR' which brings up a 'PWR Shift' dialogue on the dash display. I can't seem to find any information on what changes this makes.

    Can someone enlighten me? Will get some pics up ASAP.

    Braden

    all it does is moves the shift point further up the rev range
    eg it will normally shift at 2800 press power it will now shift at 3200 (example only guys)

    Thanks! It is as I suspected :)

    Anyone have any figures on its impact on economy?

    it also adjusts the auto clutch release/apply zones..... so u'll use more fuel most of the time even if u drive slow with pwr mode on..... cause it's designed for u to drive faster :D

    So in other words, the clutch is more aggressive between shifts? Meaning quicker shifts along with shift points higher up the rev range? Sounds fun...

    Thanks people!

    Wouldn't think of it, I am as much in favour of frugality as I am fun :)

    As said its just the shift points and read somehwere on here ages ago it is only effective up until 80% throttle. After that both modes will be the same.

    I use it when towing my boat, good to hold it for a second instead of changing up then dropping back 2 seconds later.

    I've had mine turned on constantly for around the last 6 months and noticed no change in fuel economy...

    Also locks out overdrive. Well in the VR's it does any way.

    I have a VZ CV8Z Monaro & noticed it doesnt have a "Power" button at all . So I guess it was deleted. Honestly, I never used it on my VY , So I dont think it was worth having, GMH must have thought the same!!!!:bomb:

    Also the PWR button also introduces a mode that keeps the car in a certain gear ( does not change up when you need the power) after you drive in a aggressive style on the 5 speeds auto boxes..

    Does anybody know if PWR mode in combination with the paddle shifters has any effect or does manual shift override PWR?

    Clutch? An auto transmission woks by applying pressurised fluid between a series of reduction gears. The planetary gearset on the engine side of the box controlls the take off and shift points. There is no actual clutch plate in the auto.

    The torque converter does have a lock up clutch.
