I thought that as well, in regards to the trans slip.
i just got off work and currently have accelerator pedal position, vehicle speed, gear commanded by module, torque converter slip(actual), torque converter clutch(modulated), torque converter clutch(actual), SS 1-3.

This is everything transmission related I can watch
-coast clutch solenoid control
-electronic pressure control?
-gear commanded by module
-lowest idle throttle position?
-net engine torque?
-overdrive cancel switch/hold switch
-shift indicator light
-shift solenoid 1,2,3
-speed control actuator switch coast
-speed control actuator switch off
-speed control actuator switch on
-speed control actuator switch resume
-speed control actuator switch set/accel
-speed control input switch
-speed control no switch input
-throttle position input
-throttle position mode
-throttle position sensor status
-torque converter clutch-actual
-torque converter clutch-modulated
-torque converter slip-actual
-transmission control indicator light
-transmission range
-transmission range sensor-volts
-unlock convertor for traction control
-vehicle speed
i don’t know which of these actually work for our trucks

This is from a stop going to 68 mph. Excuse the commentary.
top left- accelerator pedal position
top middle- VSS
top right-torque converter slip-actual
middle left- transmission range
middle middle- torque converter clutch-actual
middle right- gear commanded by module
bottom left- SS 1
bottom middle- SS 2
bottom right- SS 3

That shows that the shift solenoids are being commanded correctly. It doesn't show if that signal gets to the trans or not, the PCM doesn't know that.
throttle position and vehicle speed work, as do the shift solenoid commands. The torque converter, range, and commanded gear are not working, the data doesn't make sense.

There is no scanner for the E4OD. You need one that can talk to the PCM.1997 diesels were a strange breed. I think Forscan can do it. You can download it free from www.forscan.org. You'll need an ELM327 adapter to connect it to the truck.

From what I could tell the wiring for the transmission lines up to these two plugs. The circular plug, red wire has 12 V.
i went back to the transmission after that and now I have a dilemma. When I test the red wires on the trans harness and ground to the frame/a bolt I get 1.5V. When I do the same wires but ground to my electric fuel pump I get 12.8 volts. How is this possible? Is the frame/bolt a bad ground and not showing what the power wires are actually getting?
