Which brand Atf4
I ordered my filter from geno's yesterday now I just gotta get the fluid. Does brand really matter? The cheapest autozone has is 4.99 coastal. Should I pay more for the castrol?

they are all the same even Walmart brand all come from one maker!

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:

I agree and think they are all the same. I would go to Walmart and buy in bulk. But I know valvoline makes some cummins approved fluids.

Depending on your definition of wrong, you are either not exactly right or just wrong. The Chrysler specification for ATF4 (7176E) sets "minimum" requirements for certain things, among which is the base oil, GpIII is the "minimum" requirement. That is good. GpIV is better.

So since they call for GPIII like I said either will work but GPIV is the better choice. I'd say I was right other than I didn't know what Dodge called for, but that's ok because I know what my NV4500 calls for

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. :c: |
