Are there particular problem areas with these cars?

That was the first year for that trans in a 6 cyl car...fluid changes are important!

M104 head gaskets are prone to leak oil on the passenger side.

Thank's MB Doc

In reading this, I realized that this era C280 would be an M104 with the electronic 5-speed auto....
Thus the inevitable question - can this 5-speed be installed behind ANY M104 Engine??? Namely 94-95 3.2L . Please say it's so.....
