Is this your first time driving in the cool weather?

Is it actually slipping or just holding a gear?

You do know that the car holds low gear for an extended time when cold to heat up the catalytic converter, this ia also the source of the whine sound form the transmission when first driving off when cold.

If you cold test another car that uses this transmission in the same temps to see if it duplicates the issue.

If it is an actual slippage then connecting the transmission to a Mercedes develped specific computer would probably be the next step after making sure all engine hoses for vacuum and electrical are connected.
