Part Number Chart
It is difficult to identify a 6R60 from a 6R75 or 6R80 without disassembling the valve body because all three look identical from the outside. To correctly identify the transmission/valve body type that you require, look on the Vehicle Certification Label, located on the driver's door. Find the code letter/number under the "TR".
