I also lean towards over-equipping vs. the bare minimum. For reference, I have a 2005 Sequoia with the factory towing package, which included an auxiliary tranny cooler. It would be easy to tell if you have one -- it looks like a small radiator, is roughly 6-8 inches tall and 3-4 inches wide, has 2 rubber hoses connected to it at the bottom, and sits directly in front of the A/C condenser, which is directly in front of the radiator. If you can't tell, I'll take a picture. If you don't have one, get one. They are very cheap insurance ($50-$100) for your several thousand dollar tranny. If you're at all handy, you can install it yourself. It's pretty easy.

Other than adding a Prodigy P3 brake controller (which was very easy as it was factory pre-wired), I did nothing to equip the vehicle to tow our 2720SL.
