When is the last time you did a fluid and external filter change? What did the fluid look like?

If the noise you're hearing is something new and different, then there may be a problem. On the other hand, if you're new to the truck, the Allison does produce some whine when cold - it's normal.

Yes I am new to the truck I got it first of march but I guess I'll find out more when I put the gooseneck and tractor behind it if I have any real problems

A quart in 2,000 miles isn't a problem. Sure, we'd all like our engines to not consume any, but the fact is that most do. If it was a quart in 500 miles, I'd be concerned. If it was a quart in 1000 miles, I might have a compression test performed, and I might replace the valve stem seals. But a quart in 2000 miles, I'd just drive it (and check the oil once in a while)... ;)
