do you drivers in the colder (-5C and more below) countries put a thinner
oil in your gearboxes.

In Hampshire UK we were -7C (yea I know it's not that cold) this morning and
my auto box was noticeably not changing into 5th very often.

Some autoboxen adjust shifts for engine/tranny temperature, holding off on
upper gears until the moving bits have warmed up...

No. Same oil for all temps. And a lot of typical Audi countries have temps
well below you 7 degrees.
No problems. What you should do in winter is: start your car and drive of at
low revs for a while.
The old fashion of heating up the engine and then drive doesn't warm the
gearbox oil.

I use the same transmission oil all year round. However,I have noticed that
my 1998 A6Q (2.8 auto) will delay shifts to higher gears until the engine
has warmed up, especially when going uphill. I suspect that this is normal,
although it is slightly more noticeable in the winter (-15 to -20C here in
Montreal) than in the summer.
