:wtf:After trans filter change -pan and spin - the truck is acting strangely.....seems to be stuck in 3rd and the torque converter is slow to lock. Seems not to be taking commands from the PRNDL besides forward and reverse. Tow haul seems not to have an effect.

Thoughts?

You need a more advanced code reader, that can read codes from the TCM. P0700 is just a code indicating that the TCM has more codes to read...

^^^^
P0700 is the TCM requesting a MIL (Malfunction Indicator Light aka: "check engine"). All the 700 code does is tell the ECM "something's wrong" and to illuminate the MIL. There is another code in the TCM that you need to pull that will actually tell you what the malfunction is.
