Re: Hard shifting in the AM


    What you are noticing is probably the high viscosity of the oil when it
is cold. As the oil warms with use, it thins out and shifts easier.
    Even though these 75W90 synthetics have the same specs, they sometimes
seem to work differently in the gearbox. Some result in smoother shifts,
some in harsher shifts. I would be inclined to try the OEM oil supplied by
Audi - it should be matched to the gearbox design to give smooth all-weather
shifts. I've never had a problem with shifts in -40 temps and I use the OEM
oil in my trannies.
