Have a problem with my A8 4.2 Built 98

When I start the car (cold engine) it makes hellish noises from the automatic transmission.
Each gear change is then clearly a loop to hear (mechanical grinding).
If the engine has reached its temperature, the noise will be less.
Then I press on the gas while accelerating, hears when that is grinding again.
When I'm on the road so unfairly 40 minutes, the grinding is almost no longer to be heard, what can be the cause.
