VZ Auto 'Power Shift'

[zvagon]

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.

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?

[bigdaddycool]

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

[zvagon]

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!

dont drive around all the time with it on thou id suggest only using it when pulling up hills or towing, but its your car you drive it how you want

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

just take it for a drive with it on, seriously there isnt much of a difference

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...

just for my own frame of mind, why do you drive around with it constantly on

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!!!!

Wouldnt happen to be a manual would it. lol nah jjk

You don't need a power button in a V8 :P

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..

[hingo1983]

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

[06vzcalais]

active select overrides PWR

i stand corrected i knew something overrode the pwr button but it was only cruise control,

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.

No reason at all, I put it on when I drove up one of our mountain ranges, and have just never bothered to switch it off.

And I've noticed no difference when driving the car normally...

That is weird as mine clearly revs a bit higher in each gear before changing when driving carefully, it also changes down gears earlier which uses more fuel on the overrun.

[Kal123]

I'll take it off for the weekend, and see if i notice any difference.

It might just be that I'm used to how it drives with PWR on...

Yeah ive never done a back to back consumption with it turned on and off. Unless you are driving in hilly areas where holding gears would be beneficial for fuel consumption it must use more if it is revving longer in each gear.

[Escape-The-Fate]

i use the pwr button if im on a fun bit of road, as it drops gears more willingly. I havent noticed a difference in fuel..and i usually just drop back to 3rd myself on the stick if im going up hill as the car labours abit before it decides to drop a gear itself.
