I was wondering if meeting the Dextron II/III standards is enough. Are name brand ATF any better? The guy at the NAPA store said even if they did put something in the brand name ones that it still might not be all that good in the long run.

What do you guys know?

Thanks,
Brian

bbob please replymy question

This is what Ive found in another post on in the CTS-V forum, but I wouldnt think the THM440-t4 was made with synthetic even close in mind. But Ive heard its good for about 5hp in other trans.s...
