Another AT Question?

I am waiting (impatiently!) for my MCSa which is currently waiting to be shipped.

A question that I have about the tranny is whether the AT on the R56 rev matches (blips the throttle) in manual mode on downshifts?

I have a MCSa and I don't use the manual mode very often but I don't think it does.

Not that I have noticed on my MCSa. You do get a nice engine braking affect on the manual downshift.

No blip, since you really do not have synchronizing gears to deal with in the AT.

Thanks JCR & Old81,

I appreciate your experience with this tranny.

My MCA told me it did rev match.

I am also getting a new Audi A3 with DSG that does this, and, my ex Infinity G35 did this.

I've heard that it *does* skip firing for a fraction of a second, to reduce torque during the shift... but can't prove it. The torque converter kinda negates the need for rev-matching, at least to some extent...

And yes, downshifting does engine brake quite effectively on the Aisin auto.
I do it all the time when performance driving...

rev matching is done in a SMG not in a Steptronic.

Doh! Engine braking does not equal rev matching.
