Look at GM's website... see if the part numbers match. I'd be willing to bet they are different.

gm has a different end tank for manual or automatic transmissions, so the part #;s are different. aftermarkets have transmission cooler fittings on all of them. parts store is the same part # if that helps you.

A 3800 radiator shouldnt have the steam hose hookup at the filler neck area.
And the core is much much thinner on a 3800
