Can I swap my OBD I 4 speed tranny to a auto 5 speed OBDII ???????
The only trannies I can find on craigslist are OBD II 5 speed automatics
My 94 C220 has a 4 speed automatic. If the tranny will work what about the ECU and other electronic components?
Is this a plug and play operation if I swap the ecu or do I have to rewire the harness since it's OBD I --> OBD II?

nope
the 5speed 722.6 is electronically controlled.
Your 722.423 trans is vac modulated.
The trans is also different bellhousing physically
and the ecu can't be swapped
you can get a used trans at mb yards or rebuilt for about $1200- $1600.
