    Trans Line Identification - Block Cooler?

    The rear line going to the block mounted cooler on my 01 is leaking trans fluid at the fitting.

    Is this the inlet or return line?

    If anyone ever runs into this issue, Dorman #624-352 will take care of it.

    It says it does not fit 98.5-2002 trucks, but it indeed does.

    Removed leaking line, put a little high temp thread sealant on the line fitting at the trans and up at the cooler (probably not needed but doesn't hurt anything), mounted the new Dorman line, topped off fluid, and it's good to go.

    Thanks for the update and information.

    So it was the inlet, pleased to hear you were able to find the part and make the repair.
