On a recent test drive in a 2005 3.2 A4 Avant, I noted that the
tiptronic in manual mode shifted a bit faster than the 2001 did, but
I'd still call it sluggish, and I'm wondering if anything can be done
about it.

The first stage delay comes after pushing the lever to +/-. I could
get my hand back to the wheel before it even started to shift. If
accelerating, close to redline, the delay lets the engine overrev.

Does anyone know if this delay is deliberate, or just a function of
CAN bus messaging delays from the lever switch to the transmission
controller?


The second delay is the slow execution of the actual shift for the
apparent sake of smoothness. My 94 Volvo 850 auto trans engages the
next gear with a distinct kick, like a well executed manual trans
shift. The Tiptronic feels mushy in comparison.
Is thhis slippage under computer control, or is a function of oil
passage restrictions within the trans? If it's the latter, could
it be "adjusted" for a faster shift without pulling the whole trans
from the car?
