Codes:
Transmission was code 88, severed ECM and TCM or short circuit
Engine code 24, Intake Air Temp Sensor Signal (part of the AFM) short circuit or open for 0.5 sec or more
Engine code 31, Volume Air Flow Meter (AFM) Signal; When idle contacts are closed and the engine speed is 1,500 RPM or less there is an open circuit in the VC and VS signal or a short circuit between VS and E2. (E2 is sensor ground, VS is a connection between the ECM and part of the AFM, and VCC i believe connects the AFM to the TPS via the ECM).
On a side note the TCM does rely on signals from the TPS per the FSM operation description. If the IDL (Idle) points of the TPS close (TPS sees the throttle closed) it signals the TCM to unlock the the lock-up system, however im not sure it recieves the signal in conjunction with the ECM or if the ECM provides it... its looks like its in conjunction, which would me that a bad TPS could signal a bad ECM to TCM connection... but it looks like the signal has 2 ways to reach the TCM, from the VA term of the ECM and from a shared IDL connection from the TPS to the ECM and TCM.
I've already cleared the codes, and I'm going to take it for a spin to see what new codes come up. As it stands right now, I feel fairly confident that its one of these things, listed in what I think is most probable at this point:
1. TPS (Throttle Position Sensor)
2. TPS wiring
3. AFM (Volume Air Flow Meter)
4. AFM wiring
5. ECM
