Good call on the ATF cooler. If you're DIY inclined just do it yourself. Shouldn't have any issues with exhaust, it's a relatively new van and honda exhaust typically come off readily (especially the back halfs where there is less heat). If that's the only thing holding you back from DIY you're fine.
