I'm planning to do some towing, and in my past (non-Subaru) cars I always added an auxiliary transmission oil cooler, preferrably one offered by the manufacturer.
I've found that Subaru offers one, p/n D551SXA000, but it's listed only for the Tribeca. It's claimed to increase towing capacity from 3,000 to 3,500 lbs.
I don't plan to exceed the 3.6 Outback's towing limit of 3,000 lbs, but for the sake of transmission longevity (because I tow a camper on vacation, and because I will live in the Cascade Mtns which itself is hard on transmissions), I want to know what I can do to prolong the lifespan of the drivetrain. So has anyone adapted this Tribeca cooler to their 3.6/6-cyl Outback? The engine and transmission is basically the same, isn't it?
And regardless of whether you installed that particular cooler, have any of you installed any auxiliary cooler?
Thanks, in advance.
