VXR8 auto box.......

[davegreg]

I've noticed when I'm giving it the beans and kick it down, driving in 'D' mode, when the 'box goes to shift into the next gear at about70mph it feels like some sort of limiter is trying to kick in (even with traction control off) usually accompanied by a slight 'whoosh' type of sound, it only lasts a fraction of a second as it changes into the next gear. Just curious as to what it could be - any ideas, or is it normal? It has a Walky 'baby' cam and full Walky exhaust. Cheers...

That would possibly be torque limiting in the tune. Probably a combination of ignition retard and blip off throttle to protect the clutch packs during the change.

That sounds logical. It's not really an issue, just curious.
