I'm thinking I might be able to replace the Trans Cooler line myself, however I'm not sure which one to order. Looking at them I don't know which one is the pressure or return and the dealer is frigging useless.

Can someone please help me identify which is which. The leaking one is attached to the driver's side of the radiator right at the bottom.

 

The dealer should have pics associated with the part numbers and if they do not, then get the part numbers as google.them for pics to help you identify each one

 

Even a trans shop couldn't tell me. Can believe there aren't any pictures anywhere. I just ordered both, figured I'd do both while I'm under there. Mechanic wanted $240 for both, $180 for one and trans shop wanted $256 for one. Cost me $151 for both lines and $18 for quick disconnect tool from Harbor Freight.
