Will this drop in without any plumbing modifications?

Yes. This is a factory unit with OEM hose connections and transmission cooler ports already positioned for your automatic transmission setup. Swap the hoses from your old radiator and you're done.

Do I need to flush the cooling system before installing?

Good practice is to flush out old coolant and debris before running a fresh radiator. It extends the life of the new unit and prevents buildup in the new core.

What if the radiator arrives damaged?

Contact support with photos of the damage within 48 hours of delivery. OEM radiators ship carefully, but thermal damage or bent fins during transit are covered under the standard return window.
