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 J 41612 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 51 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.
