New Tranny, Old Truck

Anybody know if a 4R100-HD tranny out of a 2003 HD will fit into a 91 F150. Im putting in the HD engine and i need to know if the tranny will fit relatively easy.

The 4R100 is basically the same as an E4OD, which was available in '91, so the tranny should go in. Fitting the motor in and wiring it is likely where the hassles would crop up.
