I just had the transmission rebuilt in my 95 F350. Its a E4 behind a 7.3 powerstroke. My question is this. What is the correct RPM's for that transmission in OD lets say at 55 mph? I think that its running to many rpm for od. It will shift through all the gears so I know its shifting out right. It just seems that the OD should reduce my rpms more. Its 2500 at 55 now.
