Troubleshooting:
1. Check the transmission connector and make sure it is tightly connected. If the connector is
properly connected, disconnect the harness at the transmission and inspect the terminals in the
transmission harness and feedthrough harness connectors. Clean or replace as necessary
(Appendix D).
2. If the connector is connected, clean, and not damaged, check the solenoid circuit in the
transmission for shorts to other wires. (Tool J41612 may be useful in making this test.) Refer to
the system schematic and/or chart to identify wires in the internal harness which are connected. If
the short circuit is found, drain the fluid, remove the control module (refer to the transmission
Service Manual), and isolate the short. The short is probably in the feedthrough harness, or the
solenoid itself (refer to Figure 5–1 for solenoid locations).
3. If the short is not found in the transmission, disconnect the transmission harness connector at the
ECU and inspect the terminals for damage or contamination. Clean or replace as necessary. If the
terminals are satisfactory, check the wires of the solenoid circuit in the transmission harness for
shorts-to-ground or shorts between wires. If a short is found in one of the wires, isolate and repair
it or use a spare wire, if available, or provide a new wire (St. Clair P/N 200153 may be used for
this purpose) in the external harness. Refer to Appendix E for connector/terminal repair
information.
4. If the short is not found in either the transmission or the harness, the condition must be
intermittent.
5. Drain the fluid, remove the control module, and closely inspect the solenoid and internal harness
for damage. Repair or replace as necessary.
