How do you to tell the difference from a 904 to a 999 - 998 externally by just looking at them lying on the floor, or is this not possible with out a tear down?
very simple,go to the right side of the tranny and look for the 17 digit code on the oil pan rail.Starts with a PP/PK and then a 7 digit code,then 2 four digit codes.Once you have the numbers check on our site in the tool reference section of : www.mymopar.com and cross refence the number to ID the applacation.mrmopartech
