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

Fact of the week
The dot-com bubble, a period of large and rapid investments in internet-based companies, peaked in 2000 and saw the Nasdaq Composite index rise by 579%. Then the bubble imploded. As the value of tech stocks plummeted, cash-strapped internet start-ups became worthless and collapsed.
