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.

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
