cl203 gearchange stiff

[npat4]

Hi

I've looked all over but can't spot anything on stiff gearchange when cold or first starting, has this ever been mentioned before? if not has anyone got an idea on what it could be, when i asked my MB mechanic about changing the oil/fluid he said there is no need as they boxes are sealed for life, i had a similar problem with my golf tdi and it ended up that someone had put the wrong oil in it.

cheers
