The extra flow isn’t a bad thing, it really comes down to how you plan to use it. We upped the max GVWR on the 48 so to make things live, some things got beefed up.
The other thing that had to be considered was the use of Jake brakes. That added seal helped clutch capacity while in lockup using the Jake.
That makes sense , especially with the Jake brake that the newer trucks have. When I was hotrodding the lawn ornament, and buillding transmissions for Diesel Transmission Technologies back in 02-3, Bill ( the owner) told be to find a 48RE valvebody to upgrade to but It was around the time I was getting out of it and I never followed up. I keep looking for a complete trans now but unless I get a good deal on a core just upgrading a few of the parts that I really need from the 48 my 47 is more than capable as it is. I doubt I'll ever tow more than 10k with it.
sorry to the op for straying off topic.
