I have a customer here who is having transmission problems with his xtx. It is throwing codes 5105, 5106 and 5116. I have been able to find out info on the 5105 and 5106 codes. I don't work for a McCormick dealer and no dealers here know anything about them and don't even want to sell parts. I am hoping someone here can help me with the codes and what to maybe look for.
