    Aftermarket External Transmission Cooler Recommendations?

    Hi everyone,

    Although, I replaced the o rings on the transmission cooling lines at the radiator connection, a bit of fluid is still leaking. I believe it is the radiator side that has the problem. So, I decided to install an external transmission cooler, bypassing the radiator.

    Does anyone have recommendations as far as the brand and fitment ? I am not sure if the universal coolers are any good.

    Hi Chief,

    Thank you. It’s 2003, 1.8t, AWM, automatic.

    I am attaching the picture and the link.
    I replaced the seals in those pipes that go into the radiator.

    I would 1st pull the line that is leaking and check the O-ring. It's easy to nick when installing. I would also clean the radiator ports and try again with new seals. As far as aftermarket, ideally a thermostatic cooler would be best, but also the most expensive and complicated. A simple generic straight through design is available at most auto parts stores and any online performance store. I added a generic cooler to our Taurus wagon many years ago and it worked great.

    Thank you PZ. Replacing the seals was a pita. I think I am going to try the external cooler.

    just a thought , not much pressure if any so surprised that they leaked, maybe they sent you the wrong size , as they are really a tight squeeze/fit ,I remember really having to pull hard to remove and push hard to get in when I put in new radiator.
