!992 mercedes 300e transmission issues

[Ash]

I have a new car with 2 transmission issues. 1st when shifting from 3rd to 4th i have to take my foot of off the gas for just a sec. to let it shift and then continue on with no problems. If I don't do that it will go to **** and the engine will rev. high because it isn't going imediately into 4th. The other problem is that when it is cold it will not shift until the car warms up some, but when it does it shifts perfect. The fluid and filter are new. Any help will be greatly apreciated. Thanks
