Don't have experience with it but since these are DAL transmissions and learn how you drive, maybe try doing a TCU reset. Either way, I think Eurocharged and possibly Kleemann offer them and I've never heard a bad review in regards to either, except when they flashed Ronnie Renaldi's TCU for his SL55 with the wrong profile and he had to send it back.
