MB's policy on "GOODWILL" is simply that! THIS doesn't extend or create any new warranty. ONLY way to get any warranty is to pay money$$$$$.
HOWEVER on any goodwill that had another premature failure(less than one year) MB has stepped up to the pump again WITH Goodwill again. At least at our dealer they have.
If a car has 49,998 & a part fails & you have waranty work done to fix the problem, ALL of the car still goes out of warranty at 50,000 miles including the warranty repairs!! READ LEGAL!!
As far as installing the trans computer goes: it is simple, however the trans must be "adapted" to this new ECU.
