it's the E4od. Is it possible to upgrade is trannyvia rebuild. i.e. better TC valve body??? It obviously has a shift kit in it now and shifts very firm. The way I see it right now the only 3 major faults of the truck for my application are.
1. The tranny.
2. Lack of aftermarket perfomance enhancments
3. Not 4x4
1) BTS or ZF5 conversion would be the ticket.
2) You'd be suprised what you can get out of one of these trucks without a whole lot of aftermarket choices. But seriously, to wake up one of these motors.....turbo, IC and snow. If that isn't enough hyperdrive for you, rumor has it the Moose pump will put more oomph into it. There really isn't much else you need. One more thing, if you really want a five inch exhaust system, look no further than MBRP for the OBS PSD kit.
3) 4x4 can be had for the f450 via Marmon-Herrington. Very pricey tho.
On a sidenote, going off-roading in a f450 is nothing but pure punishment.
