Hi, I have a big problem, went to a service,they changed transmission oil but there they set up new Pinion factor to my TCM with Launch diag software, now my speedometer doesnt show correctly,there are 3 options for tyre sizes in the software ,none of them does the correct setup, before that the seting was set to "others",now is R17217,and 2 more R15 and R16,no option "others". Is there any option to reset this to previous state?
Regards
