My '02 MCS was updated with an '05 6sp/LSD (a real jump in performance)and apparently was mechanically a simple swap. However, the cruise control is intermittently functional and a number of error codes are now appearing which the Dealer attributes to an incompatibilty between the computer control and the different gear ratios. The Dealer is unable to find a software version that will correct the mapping issue. Anybody have any ideas how to get my cruise control back (short of installing an older trans)?
