[YZ250]

Can't answer your question directly but,

I was overtaking a line of cars and immediately prior to that I had selected gear 2 manually. I swung out to start the overtake, shifted to manual 3 with my foot planted in the carpet, shifted up again, and then again,  at which point I lost momentum and the car was revving it nuts off.  I looked down at the shift and I was in neutral at quite some speed.  In panic I shifted up and for a split second I was in reverse. This was instantly followed by an Aaaaahhh from me as I shifted back to drive. I must have just beat the gear engaging with my lightning reflexes. 
No harm done in my case, but it taught me to keep my hand off the release button whenever using manual shift, as you'll notice that you can select drive from neutral without the button but not reverse.

Any of the forward gears, it won't go in to an inappropriate gear.  Reverse to drive, it will do a significant speed.  It will go in to park at 20mph, to the detriment of the rear tyres.

It will go into reverse whilst going forward, *BUT* I've never tried it at a significant speed, so I cannot say what would happen in that scenario.

I was using the gears manually on my auto box. Just for some extra engine braking following another car, as I'd misjudged it slightly.

I can't say I've noticed any useful engine braking effect from using the automatic gearbox like a manual on the Omega, or on any other automatic for that matter.  And I've owned and used automatics for the last 40 years.  You get some advantage in extreme road conditions - ice, or excessive surface water, or mud - but mostly it's best to bung the thing in 'D' and leave it to sort itself out. 

Never found much use for the 'S' button either - TBH I'd forgotten it was there on the Omega.

You're not driving it hard enough then. Sports settings make a noticeable difference to the gear shift points.

My Omega used to go like a bat out of hell if you floored it anyway.  S button didn't seem to do much. 

In the days when I commuted from Suffolk to West London, I actually spent a week using it more or less permanently.  As I recall, it didn't actually improve my driving experience, and I had to buy more petrol.

less so on the 2.5/3.0 with the latest firmware, although it does affect the downshifts.

S is pretty essential on the 2.6/3.2s

My car car has had the later gearbox firmware installed almost from when I bought the car ..... pre OOF. I notice the difference.

Is your kickdown switch working properly? As in kickdown, a v9 GS820 TCM will only change at redline.

Pretty sure it is, it certainly was when I drove it more often than I do now. I know that on occasion when I've put it in S & forgotten, it doesn't take me long to realise it's still in S because of the way it drives ie shift points/revs

Anyway, the point I was making to Jereboam is that Sport should make a difference enough that it's of use 

[tidla]

Often seen this motor smoking its tyres from a stationary start.

I assume its a case of some proper revvs and dropping it into drive??

[05omegav6]

Yup and no electronics to say 'No' ...

  Remind to never let you drive any of my cars. 

You just give them a boot full from a standing start.

I have had four V6 Omega's, 3x 3.0 and my current 3.2.  NONE of which have ever made a difference when accelerating with 'Sport' Mode or not!

It doesn't add power, torque or re-map the ECU..... All it does is tell the transmission not to change up so soon - which kick-down does on WOT.

It's a gimmick, it's a pointless button which I don't ever thinking about pressing, because it's pointless.

Did I mention it is useless?

NB: Anyone who can get their Auto Omega to spin up in the dry really needs to check the quality of their tyres (please no more tyre threads).

WOT with S pressed or not makes no difference, but other than WOT S does make a difference. You don't always need WOT to overtake, & S is generally enough to ensure that the transmission changes down for the manoeuvre. I don't consider it a gimmick ......  but whatever.

If you were in a manual, you wouldn't always need WOT to overtake, & you'd probably let the car rev a little higher if you were driving a little more spiritedly ...... that's what S does - and if an Omega does the same as a Senator, S also prevents changing up to 4th unless you're doing silly mph

Can't cant talk for the 3.0...

But on the 3.2 it certainly does make a difference. Especially applying power at the apex.

However....


THE most noticeable difference is applying engine braking on the over run. I wonder though, if gay drivers don't notice, if they rarely use it. Due to adaptions?
