Hello
I have a 2014 outlander se 133k awd and im having transmission issues and was told its only going to get worse. I was told in order for me to get a used transmission I have to match up my last 8 digits of my vin to the doner transmission..is this true? Does it have to be an exact match? going crazy here trying to find a replacement. I was told even know I can find the same model ,year and engine size that I need to make sure the vins match. The mechanic at mitsubish said that it would fit in most likley but not work properly..very confused ..any help would be apprecitated.
thank you

 

This link should help. Might want to find a new mechanic.
