I don't know about relearnig the throttle body with a scantool; I only know the Idle for 30 seconds method; it relearns automatically. Maybe you really mean learning the Crankshaft sensor?
New ECM needs new programming.
New TCM needs new programming.
The crankshaft sensor needs to be relearned every time either the sensor or the ECM is messed with.
I think the pinout on the TB was changed at some point, check the wire colors against the diagram.
Nobody knows what the TCM needs with all the rebuilding of transmission gears.
