48RE strenght, and frame question

664 Views 6 Replies 3 Participants Last post by  03cumminsmtz
hey, im curious, i have the 250 cummins infront of a 48re trans, is this the same trans used on the big 610 motors? how much power can i safely run through this transmission before i have to think about upgrades? i am running 35" tires with the 3.73 gear ratio.


also, on another note. is there anything in our frames, like wires, or lines or anything at all? im workin on a little bit of a custom project, that would involve running a winch line through the entire frame rail, as long as i wouldnt cut through anything.. thanks

The 48RE is the replacement for the 47RE and is the same in all Cummins motors. If you have a 48RE with your California smog motor then you have a late build 03 and all the trannys were the same.
what is different between my motor and a regular 305 horse? is the injection pump/lift pump the same? different settings?
I could be wrong but I think the 305 HP was the first with the common rail injection and was considered the "HO" version.
yeah, i thought so too, my neighbour has a 03 305 1 ton and it looks identical, except for the ratings.. im just curious what the difference is, and what the difference might be if we would run the same chip or something
