Default Trans Swap

48RE to 46REF?? is it worth it? Was going to buy a 3500 with the Aisn, but returned to reality. That would of been a lot of Denaro to tow 5-10 MPH faster. The difference OD4th and 3rd with the 48RE is to big. At present, 60 mph with the 48RE in 3rd is like 23-2400 rpm! should I push it more??

How much you towing?!?
Unless it's like 20k# you probably just need to put that sucker in "D" and let that cummins work in it's sweet spot...under 2000 rpm...imho.
Or like Clunk said, change the rear ratio.

1) Trans temp gage 2) spin on filter kit in pressure line to trans cooler 3) more trans cooler 4) don't let it hunt between 3 & 4. Increased line pressure is good too. JMO

And it won't haul that in OD ?
I mean, yeah, it's gonna drop 5-10 mph on a good hill, but it oughta be happy running 65 in OD.
My 99 would run 65 at 1800, or 70 at 2000 for that matter in OD pulling a 32 ft camper.
I could pull the shed trailer empty at 70 no problem, or with a couple 8 wides, and it weighs 7-8K# empty.

Waste of time if you ask me. And twice the expense when you have to rebuild it. Want an over drive or splitter? Install a Gear Vendors.
