The ZF is about a 200ms change, some of the DSGs can do a single change in 8ms.....although the second change is MUCH slower and down shifting/kick down is very slow at 600ms  as the engine ECU has to blip the throttle to match the crankshaft speed to the DSG input shaft

I think that equates to 0.2 sec......or 1/5th of a second in old money. Presumably far quicker than the the 3 speed auto (GM or Borg Warner) used in the XJS forty years ago.

Very much so if not only because it has so many more ratios, so the rev change is much less. (and you haven't most likely got an enormous V12 crank and flywheel to accelerate / decelerate).

You’re not going to find a three year old Vauxhall that’s had gearbox oil and filter changes. Why would anyone want to do that within three years? My 2.0l diesel auto fluid can only be changed by a specialist, according to Honest John, as the torque converter has to be drained.

For which read, ^^^ this so that we can gouge as much as possible out of you.

I think touching an auto box that is behaving normally before a certain time is taking preventative maintenance a step too far, Chris. You’re probably right, it would be expensive but people of ‘a certain age’ have got to realise that cars are not built to last 20 years nowadays, or at least folk don’t expect, or even want, them to last that long.
My astra will be long gone before the gearbox needs any work doing.
10 years or 100,000 miles is when most people consider a car is past it.

And I am back in the room.... What you say here is I am afraid exactly the problem I am encountering. Everyone knows you must change the engine oil and filter and so do that especially on diesels. Everything else is unessary and an expense. Hence the 50k miles( I think) DSG gearbox oil and filter change is skipped. then when they get to about 100k miles they suddenly realise they should have done it. So they flog the car. By the way 100,000 miles is a young car here. I have seen two year old cars with that on.

Yes, but you asked about Vauxhall’s, and they don’t have DSG boxes, they have torque converters.

What type of box are you going specify in your new car, now the Astra is a pile of ash in that car park ?   

[TD]

The Auto box in the Zaf is traditional one, no silly clutch setup to make it like a manual or what ever DSG does.

It’s fine, unlike Omega it appears to disengage at lights when in D, so the drag is a lot less when waiting at junction. Zaf changes smoothly and so far all good.

Have you looked at Insignia? (Sure you probably have) suspect one of these in auto is about as solid as you would get for the money.

And what a pain in the arris, that is! I once owned a Vectra 2.5 V6 auto that did that....Stamp on the go pedal for a rapid depart and the first thing you notice is a slight delay then a ruddy great thump as 1st engages!
When i wanted a rapid go, i quite often use to hold the handbrake on and give it slight revs to stop it disengaging 

[Varche]

I did ask about VX's and also other auto boxes. following the comments about Dsg and powershift on the other thread.

Had a look at an Insignia but wasn't impressed by the equipment level. Not many high specced models about. Did have a test of an Astra estate with 163 bhp engine and auto box. Drove well but wasn't impressed with the boot.

That’s the engine I have and I like it. Plenty of poke when needed but quite happy footling around, and I’m getting 44mpg around town.
Afraid I can’t stretch the boot for you though. Sounds to me like you need a transit van.

The auto Astra G that SWMBO once had did the same .... not the best of ideas.

[STEMO]

Mine doesn’t seem to do that, it’s away as soon as I lift my foot off the brake pedal, unless the hill hold is on.

The AR25 in TD issue is more to do with the box being marginal on its ratings for the torque output. The vast majority of failures were probably on chipped Omegas, although the box wasn't as long-lived on non-chipped TDs as the rest of the AR25/35 cars in the range.

I think is was a poor choice to combine the 2.5TD and the AR25 by GM (whether forced upon them or not).

I'm trying to remember if I killed the first AR25 before or after I chipped it, too long ago now. Definitely the short lived 2nd one was post chipping

I concur, and it can't be healthy for the box.  If you don't like the drag (or want to hug trees), every single auto I've ever driven has a N setting.
