confused about synthetic gear oil

[TM]

No problems with the gears or the synchros that I can really
determine, but I've noticed a couple things about really cold
weather and Audi gearboxes- MT-90 in the 200q makes it rather
difficult sometimes to find reverse when the car is started in
the morning with a cold gearbox in 20F weather. Once I'm underway,
I tend to take it easy with the shifts with a cold engine and
gearbox, never had any problems with shifting except for that
reverse problem, which is sometimes cured by putting in neutral
and clutching in and out, or going into 1st. Weird.

With the A4 on factory fill G50, no problems selecting gears, but
2nd gear sometimes is very difficult to engage on a cold gearbox-
to the point where I have to double clutch and pause in neutral to
get it to shift.

I think it's just the cold weather- the Beetle takes a good half
second to engage Drive from Reverse when pulling out of the driveway
in the morning.
