July 28, 200421 yr Any parts store should have them. They should have different sizes for different size vehicles. Just ask for a small one. Be very careful when making the connections. Make sure you get the cooler plumbed in the return line from the radiator. Be aware that the mounting system they use can rub a hole in the radiator.
July 29, 200421 yr If I installed a cooler, I would completely disconnect the radiator cooler. I found it easier to leave the radiator part alone, then use an adapter (or just a hose) to link the two of them together. So, it goes like this: Hose from tranny goes into radiator, out (of the return port) into the new cooler, then out (from the cooler out port) into the tranny on the return hose.
July 29, 200421 yr I found the best price at a place called Makco Distributing, Inc. Look under bulkparts.com. Was around $30. Shipping was fast. Got it for my wife's Nissan Maxima but haven't installed it yet--I refuse to "tie" it to the car's radiator. Am going to fabricate a support so it is freestanding in front of the rad. By the way, there are good arguments for plumbing the auxiliary cooler in series after the car's radiator rather than bypassing it.
August 3, 200421 yr I'm no novice, but I'm no expert either. Why does a subaru auto trans need a cooler? Are there problems with them overheating? I know what a trans cooler does, just wondering in this application.
August 3, 200421 yr Nearly all auto trannies can benefit from a cooler. Most cars run the fluid through a cooler integrated into the radiator, which limits the minimum tranny fluid temperature to approximately the coolant temperature. Auto trannies will last longer if the fluid is cooled to a lower temperature, and often during towing or heavy use the integrated cooler won't keep the fluid temperature low enough.
August 3, 200421 yr Just about any automotive radiator shop will install one at reasonable cost. Many trailer shops and UHaul trailer centers will install them as well.
