Same problem.
Still no MIL or DTC set.
Will be able to check the fuel pressure in the morning when I get to work.
Once again I'm thinking transmission..solenoid not holding proper line pressure,
rather than clutches slipping as the fluid looks and smells good.
There is no sustantial increase in rpm on the tach when the truck is shuddering-bucking.
....ding...fries are done!

your vehicle requires 60psi...with a new pump the pressure better be 60psi...
if the pressures are the same 44-50 psi then I would get another guage and also test the cal. on the guages used....drop the pressure guage and the cal is n/g...
with the low pressures if correct that you had,,,, with a new pump you should have seen some difference...as most find these pressures are big trouble ...
dtc should show random misfires...if not then the diagnostic's are off..
