Need help! Transmission cooler line?

[mj.87]

My transmission cooler lines are leaking! I have looked online at replacements but I’m not sure what I need. The metal line is what is rusted out and seems to be the problem. Does anyone know what the part number is on that metal line? I have the AW-4 transmission.

is this what I need? Dorman 624-334 and Dorman 800-714

Here are the Dorman/Help numbers for all the items:

 

Pressure Hose 624301

Return Hose 624300

Metal tube 624334

Fittings at Tranny 800714

 

I would replace all of them at the same time. Rock Auto has them all.

 

Quick Connector Fittings:

83502745, 5/16"

83504447, 3/8"

1 Return Hose 624300

1 Metal tube 624334

2 Fittings at Tranny 800714

1 of each Quick Connector Fittings:

You won't need the 3/8" quick connectors as the new lines already have them. :cheers:

You have been so incredibly helpful! I would be lost without this club. I do have one more question. How many of the 5/16 connectors do I need. Thanks.

[HOrnbrod]

Same for those. No need.

 

Also you will need to p/u a quick-connector removal tool as below to remove the old lines. NAPA carries it.
