722.9 transmission detachment

Question by mtmercedes posted 1 month ago in 2008-____ (W204)

Hello,

I have an 09c AMG that had a transmission rebuilt and now I am looking to detach the old TCU so that I can marry up the new scn coded one.  The rebuilder seems to think a quality scanner like the Matco brand can do this.  Problem is there are none in my area and a dealer is 200 miles away.  Any suggestions on a decent autel or equivalent scanner?
