Engine/Transmission (1998.5 - 2002) How to tell a 47RE from a 48RE?

[Davcruz]

Is their a way to distinguish a 47RE from a 48RE? The warranty paper I got with my transmission states it is a 48RE. I bought the truck second hand and the only document I have is the warranty. Will a 48 even fit in a 2001. 5 truck?

The 48RE was released in January 2003 so it's not OEM.

Maybe dealer transmission replacements end up being 48REs being swapped in place of the 47?

Would/can a 48 work in a truck that came with a 47?

So do they look the same externally? Is there a tag somewhere that I may be able to find?

call Dave Goerend he would be able to tell you.

I am sure there is no external difference, other than the numbers stamped in the side of the case.

Will the computer accept / work with a 48?

I think all the factory/dealer replacements are 48's. They use the same insides, just a different valve-body? When I was looking for a transmission, I could get 2 different ones from Dodge. The old style for 2800 and the updated one for 3800. The guy told me the old style only warrantied for 1 year or 12K miles. The updated one had a 3 year 60K mile warranty.

That tells me the updated one was probably a 48 with a 47 compatible valve-body.
