Open Circuit "G" solenoid. (forward clutch solenoid)
I suspect a 1992 has the two connector ECU and the 24 pin rectangular pass through connector on the transmission case.
I would examine the pass through connector paying close attention to F-1 pin (top row 6th position over) that will have a white wire #104 connected to it. That is the problem circuit.
To determine if its inside the transmission, on the transmission case connector, check resistance between the F-1 (top row 6th position over) and the C-2 (middle row 3rd position) terminal. There should be around 3 ohms. If that checks ok, then you most likely have an an open in the chassis harness. The suspect wire would be, wire #104 (white) that goes between the F-1 pin on the transmission pass through connector and the A-4 pin on the blue ECU connector.
Good Luck,
Doug
