My wifes A6 will not shift up from first when cold. Car must run for about 5 minutes first, then shifts fine. Cold being anything below 40 deg F and it is stored in the garage! I am told by Lithia Audi of Reno NV that this is a normal condition for the 99 A6. I don't buy this, been in this business too long. Anybody got any ideas? Figured fluid and filter change couldn't hurt. 55K on clock, and doubt trans. fluid is anything but original fill. Also need fluid type if anyone knows. Have a hard time paying AUDI $15 a Qt for theirs.

I ALSO QUESTIONED MY FIRST UPSHIFT ON COLD MORNINGS BACK IN "97". AS THE MILES ADDED UP IT BECAME LESS NOTICABLE AND NOW @ OVER 100K I DON'T THINK IT DID IT MUCH EVEN ON THE COLDEST DAYS THIS PAST WINTER. I THOUGHT IT MIGHT BE INDICATIVE OF FUTURE TRANNY PROBLEMS BUT THIS IS APPARENTLY NOT THE CASE. FUGETABOUTIT

Hello. I'm not sure if my mom's A6 is a '99 or a '00, but it has the same problem. Well, it's not really a huge problem. You just can't race out of your driveway :-P

My 01 A6 does the same thing. Ive assumed it was the norm. Im sure you have nothing to worry about. No car enjoys the first few minutes of startup/rolling, my last car which was a manual tranny would be cumbersome when shifting after a cold start. After it was warmed up for awhile it had no problem at all, so I remembered to warm up for a few before moving. Your just getting alot of parts that have been sitting a while to start to move again quickly which is usually rough at first. Good luck!

I make my wife wait until the rpm's drop to around 900, before taking off.
It seems to shift just fine after the engine/trans warms up and kicks down.
This seems to happen whenever the car is cold, regardless of the outside temperature.
I suspect just another Audi characteristic!
Besides, w/the 2.7T, you should ALWAYS let the turbos warm up before launching.

Well, fluid and filter did the trick. Drained the dirty, black factory fill which AUDI said did not need to be changed measured almost exactly 5L. Refill took 5.4L of AUDI O.E.M. brand fluid, after cleaning pan, and replacing filter with new. Audi service finally devulged that temp of trans needed to be 37deg C which is 98.6F. Fluid check is done with engine running, and trans at temp. No fancy analizer needed, just an infared temp gauge. Fill trans level to top of large access plug recessed in bottom of pan. This is actually a tube that rises about 1.75" from pan bottom to determine level. Trans. must be shifted (engine running) in each gear for a few seconds to refill all passages and clutch paks. Final level check is made in PARK with engine running. Once level has been achived, reinstall plug BEFORE SHUTTING OFF ENGINE! Otherwise lots of your new, very expensive fluid will be flowing into your armpit.  Vehicle must be level, a hoist is a nice item to have in your shop, otherwise 4 good jackstands will do. As the fluid will need to be pumped into trans from the bottom, you will find a small lube pump at most autoparts outlets for under $10 and a short chunk of 5/16" copper tube bent to a hook, to be an indespensible part of this equation.
Transmission now behaves properly at all temps and speeds. Smoother shifts when warm and when cold.
Now THAT should be a charateristic of this fine machine.
BTW That shudder in First and Second on yours (DKLandry) means clutches are slipping. Do not let that continue. Early death of that expensive gearbox WILL BE the result. Try the oil change. Do it yourself for about $140.00 with filter kit off the internet, and fluid from AUDI. Cheap insurance.
