Which brand Atf4

I used Valvoline full synthetic after having my valve body out for a SK-48RE shift kit install along with the regular service last month. The 7176E Chrysler ATF+ spec (I believe dangerous refers to above) calls for a minimum GpIII base oil, which is found in most of the less expensive brands like the Coastal type you mention. As long as it is one of the licensed oils listed here, you should be OK:

They don't "call for gpIII." GpIII is the minimum.
Manufacturers can use any base oil they want and call it ATF+4. But in order to be officially licensed it has to be gpIII at the minimum. GpII won't be licensed, and gpIV is a better full syn base stock.
But of course you can run whatever you like, Dexron, whale oil, whatever, based on your comfort level with transmission repair or other personal preference factors.
