I think I'm going to be in a position to make a "double switch" of transmissions between 2 190D's. My current ride is an '84 190D 2.2 5 speed. It runs and drives fine.

I just won an auction for an '87 190D 2.5Turbo with a bad transmission (automatic). Right now, my plan is to take the 5-speed out of the 2.2 and put it into the 2.5T car. I have done this swap before, and it turned out great. (I wish that I had never sold that car).

Then I'll put the automatic into the 2.2 car. The part I don't know about is the vacuum for the auto trans in the 2.2 car. I will either have the auto trans rebuilt or replaced before putting it into the 2.2 car. Was there something special about the IP's on the 2.2 with the automatic transmissions? (i.e. different between the automatics and the 5-speeds?)What is needed in order to get the vacuum signal correct for the operation of the auto trans?

Any insight would be appreciated.
