W140 4speed transmission shifts??

the 4 speed in my 92 600sel always up shifts "firmly". it's not rough, but its the complete opposite of seemless. but the down shift is completely seemless and is unnoticeable. I heard that the transmission shifts somewhat depend on what type of lubricant fluid is in the tranny but i'm not so sure. how does every one elses' w140 shift?????
