The transmission I have is from a c230k. The .6 came on any car 1996 v8's and 1997 all cars in the U.S. The bell housing on and m104 and m111 are the same. The tcm is from a company called Powertrain Control Solutions.
The tune is very difficult. I have been working with the company on solving all the problems, still in progress. I have considered offering that as a package or
an install at my shop. But I would like to get a little further. It works just fine but the shifts are not consistently good. A little to firm for some mercedes clients.
Good for racing though.
