I don't get it either - kinda' like good lovin' - of late...
But when I disconnected the battery sunday, the DTC's cleared, and everything functions perfectly.
This morning, the guages flashed again, so I'm about 100% positive that the ignition switch solenoid under the steering column is faulty. Another poster said that 'circuit 1020' gets shorted out by this fault, and can set several DTC's. Mine had two DTC's that he listed - P0740 (TCC (Transfer Case related?)), and P0753 (Shift Solenoid A(of tranny? or transfer case?)).
I'm guessin' the tranny malfunction and the X-case malfunction ARE related, if only by a common ECM circuit.
Chilton's does show the X-case, and the tranny range switch, AND the (blinking) instrument cluster on the same circuit, but there is no numerical designation - i.e. 1020.
Got any ideas about what the ignition switch solenoid is called, to search ebay?
Maybe I need an O2 sensor too???
