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

 

First of all the had no reason why to go change your pinion factor doing a transmission service. Second if they ****ed that number up then they get to take it to the dealer and pay for a dealer tech to change it to your tire size.

 

Yes, I told them so, but here in Bulgaria aren't many Chrysler technicians..

 

not your fault take it back to them make them pay
