Tranny Cooler

  1. I am planning to convert my 65 Vert from a C4 to a 91 Mustang AOD this winter. I want to add a trans cooler but not sure where to put it. Does someone want to tell me where to stick it? ;)
     
  2. Where the sun don't shine!!!! Haha!

    Really though, in front of your radiator or on the side of your fender apron underneath the fluid bag/tank might work. Are you running hard lines or rubber?
     
  3. The transmission people I talked with recommend running the fluid through the radiator before going to a cooler. The plan is to run the hard line to the radiator with a rubber line out of the radiator to the cooler and a hard line back to the AOD.
     

  4. I agree... and defiantly in front of the radiator... that way when the air blows through your rad. then it will also go through you cooler.
     
  5. I put mine here

  6. Does having it in front of the radiator affect engine temp?
     
  7. what he has in mind i think will be the wrong shape. he will probably want something more, shall we say rounded for your suggestion.:p:rlaugh:

    not really. but the best place for a trans cooler is going to be in the coolest air stream possible, he might have to hire the fonz:D:D
     

  8. Or he could be like the guy from beerfest and be s***ing pancakes for weeks.:rlaugh:

  9. That will work fine.
    But I've had mine running straight to the cooler for years with no issues.

    My thinking was to get all the heat out of the radiator I could.
     
  10. i might take issue with that routing. transmissions want consistent temperatures, not just cool temps. and a way to get that consistent temperature is to use an aftermarket cooler that is way over sized before the cooler in the radiator. that way you get a more consistent fluid temperature back to the trans of about 210 degrees. it also helps cool the engine a bit as well.
     
  11. I run an after market cooler in front of the radiator. 8" convertor on the street, temp stays at 210-220 on the exit line and 160-180 in the pan. Usually, the temps in the pan match the engine temps. I don't have an integral cooler in my radiator.
     
  12. Thermostatic valve on bypass to the tranny cooler when open... forget running it through the radiator =)

    It is more complicated in some ways but I like this method best personally.

    If not, run it to the cooler first then to the radiator.

  13. Thanks for the suggestions! I have a B&M cooler and the tranny rebuilt. One more question... which fitting on the tranny is the output and which the return line?
     
  14. http://www.transmissioncoolers.us/H7B.html this is my cooler if the B&M doesn't work for you. If the lines are the same as the TH400 leaves from the lower port and returns back into the trans on the top one.
