I have a 1996 E-Super Duty bus I use for a car hauler that currently has a 460/E4OD in it (4.63 rear and 13,600 loaded weight). I have a good 1993 12v Cummins and also fresh 2005 5R110 trans from a 6.0 truck that I bought. I have heard stories of all of the problems using the PCS trans computer with the 5R110. Can anyone give me any guidance or tips? I really like way the 5R110 works in 6.0 Ford trucks, but maybe I should go with the E4OD or a 47RH or ???? Will most likely change the rear ratio to 4.10 when I do the engine swap.
