My bet since it is in all functions go with the easy check first in the inching system. If all is ok there start a the pump pressure.

"it's not rocket surgery"
There should be a total of 5 different readings: main pressure, torque converter inlet pressure, torque converter outlet pressure, clutch pressure, and lube oil pressure. All are tested by using ports on the valve body.

What are the pressure readings? could be misadjusted linkage, slipping clutch, bad pump, etc. Without pressure reading it just a guess
