tranny cooler installation
O.K. I'm going to try and install a new BIG tranny cooler this afternoon. Here is the pic of my stock crap one. When I disconnect the two lines from the stock one do I just connect those two to the new one? Surely it's not that simple besides mounting it. Also, what size are these stock lines? This seems like a simple install but nothing ever seems to go simple for me.

The one I put in yesterday has 1/2 inch lines as well but you need to step up to that at some point a 3/8 (or what ever it is) to 1/2 inch adaptor, then back down again to return it. Are you going to run it through your radiator or just bypass it as you are now?

Okay, I have a little more info now. The line from your tranny is a 5/16 line and the one going into your cooler(at least mine is) is a 1/2 inch line so you will need a 5/16 to a 1/2 inch adaptor before the cooler at some point. Then the return line is the reverse 1/2 inch back to 5/16. The adaptor is hard to find so start early. NAPA doesnt carry them and refered me to EVCO House of Hose here in Salt Lake. I plan on rerouting my line back through the Radiator since I have read ( Thanks TJBEGGS) that this does help pull some heat initially from the tranny fluid before it enters your cooler. I mean, the whole point here is to lower the fluid temp, why wouldnt one take advantage of all the tools available to to them to get the job done more efficiently? Reek

Upon futher investigation, I will bypass my radiator and just run it through my cooler.So your pressure line is going through the radiator first then to the cooler then back to your tranny. If you dont bypass the radiator you will hook it up exactly the same. IN your set up the cooler is the last thing the fluid is seeing befor it goes back to the tranny. ie leave Tranny --> goto radiator--> Exit radiator--> Enter cooler --> leave cooler--> back to Tranny is the order your fluid is going in.

Don't panic yet. Looking at your "crappy Stock" cooler that has worked for 270k miles, disconnect the two rubber lines where the hose clamps are at the cooler. When you see what it is you are buying will need to adapted (connect the existing small hoses to the thought to be 1/2" fittings) to the new cooler. Without seeing the new cooler I would use two 5/16"hose barb X 1/2" NPT male fitting and two 1/2 hose barb X 1/2" NPT female. Thread the 5/16 fitting into the 1/2" fitting. Connect the 5/16 hose the the 5/16 side and the 1/2" hose the the 1/2" fitting once the cooler is mounted and top off the tranny.

Tndiesel, I will pass on some final info for you. When you are all done, you check your fluid level with the truck started. Add the fluid ALITTLE at a time until you get it to the right mark. I changed all my hoses and put in a new 6.0 SD cooler and it took less then a quart of fluid to get it back up to the correct cold mark. I will check it again when the truck is warm to verify the level is correct. Good Luck. Eirik

Did the cooler get there yet?
