only occurs when cold, winds out for considerable time then works fine ,usually once or twice and that is it. Ideas?

Design..MB started catalyst warm-up in 1990, they delay COLD weather shifts
to allow the cat to come on line quicker.

Its also holds in gear until about 3000 rpm when first started cold. Is this normal for this model?

Are you saying the engin is warmed up (80 C) when it is doing this?

Outside temp shouldn't matter... only coolant temp.

P.S. Driving hard when cold causes excessive wear on the engine.

engine is warm, perhaps not at 80 but close

Perhaps you are a tad low on tranny fluid?

I wouldn't worry about it unless it's happening above 80 C.
