TRAN SYS FAULT Message -- TranSol# (1 through 6) Log Code
CIRCUIT Status Code
This fault message will be displayed if the control detects an open circuit to the
appropriate transmission range clutch valve. Computer neutral will be selected,
and the message displayed until the fault is corrected and the control power
cycled by the key switch. The circuit can be checked by removing the J4 cable
and checking the appropriate terminals as identified in the chart that follows.
The proper impedance for each coil is 5 to 11 ohms.

An intermittent status code may be caused by an intermittent or a
temperature sensitive fault in the valve or the wires between the control
and the valve. Look for any trends in occurrence of the status code,
such as only when transmission oil is cold or hot. Try to check valve and
harnesses immediately after an intermittent code occurs.
