Interesting read. I was just going to change the fluid & filter in my 96 ram 2500. Its a 48RE behind a V-10. I just turned 100,000 miles. It was changed twice prior by the dealer while it was still under warranty. Would a 96 still be 3 or 4? I just bought a case of 3 but I can use it in all of the cars if I have to.




your 96 should be a 47RE unless you retrofitted one in .

it calls for +3 , but the factory has said that +4 could/should be used in place of +3.
