OK.. I got ya...
I think the first thing I would do in your case is Disconnect the Batteries for about 10 minutes this will Clear the codes in the PCM
then hook the batteries back up .... then turn the Key to the RUN position and see if the OD cancel light is OFF (this is normal state)
then you could press the OD Cancel button to see if the Lamp comes on (it should come on) then press the button again and the Lamp should go out.
this has just verified all codes are cleared.
then Start the Truck and warm it up and verify if the OD cancel lamp comes on or not.
at this point IF there is no Faults then you can do a Test Drive around the block.
IF the OD Cancel Lamp comes on before you get a chance to test Drive then Don't do the test drive.. pull the codes again and hold WOT while you pull the codes and let's see what you get, Then we can go from there.
When I get a chance I'll send you my E4OD trouble shoot Guide it is too large of a file to post in the forums.
Mark may also see this Thread and Chime in.
EDIT: sent you a link in PM to the troubleshoot Guide it also has the schematics that you may need.

ok the code 29 is low VSS signal
you might want to check the wiring from the PSOM to the PCM
what the code is saying is that at some point during operation the Vehicle Speed Signal is dropping out.
PSOM= Programmable Speedometer/Odometer Module ...have you noticed if it has been reading erratic ?
code 23 is the FIPL sensor or TPS that is mounted to the Injection pump
you did mention that shift points didn't seem correct so you will want to inspect that circuit.
That code "1" is probably just a separator as it is not a Valid ECC-IV code.
