Step
1 1. Install the J 39775 jumper on the transmis-
sion 20 way connector.
2. Using a DVOM and a J 35616 Test Adapter
Kit, measure the resistance between termi-
nals A and E (1-2 Shift Solenoid)
Is the resistance within the values indicated?
2 1. Disconnect the 1-2 Shift Solenoid Valve from
the Automatic Transmission Wiring Harness
Assembly
2. Using the DVOM, measure the resistance of
the 1-2 SS Valve.
Is the resistance within the values indicated?
3 Measure the resistance between terminals B and
E (2-3 Shift Solenoid Valve)
Is the resistance within the values indicated?
4 1. Disconnect the 2-3 SS Valve from the Auto-
matic Transmission Wiring Harness Assem-
bly.
2. Using the DVOM, measure resistance of the
2-3 SS Valve.
Is the resistance within the values indicated?
5 Measure the resistance between terminals S and E
(Torque Converter Clutch Pulse Width Modula-
tion Solenoid Valve).
Is the resistance within the values indicated?
6 1. Disconnect the Torque Converter Clutch
Pulse Width Modulation Solenoid Valve from
the Automatic Transmission Wiring Harness
Assembly.
2. Using the DVOM, measure the resistance of
the TCC PWM Sol. Valve.
Is the resistance within the values indicated?
7 Measure the resistance between terminals C and
D (Pressure Control Solenoid Valve).
Is the resistance within the values indicated?
8 1. Disconnect the Pressure Control Solenoid
Valve from the A/T Wiring Harness Assy.
2. Using the DVOM, measure the resistance of
the PC Sol. Valve.
Is the resistance within the values indicated?
