Turn ignition off to the lock position.
Disconnect the Transmission Solenoid/TRS harness connector.
Ignition on, engine not running.
Using a 12-volt test light connected to ground, check the Transmission Relay Output
circuit in the Solenoid/TRS harness connector.
Note: The light must illuminate brightly, if it does not light, or lights dimly,
the circuit must be repaired. If there is any doubt, compare the brightness
when testing the circuit, to the brightness when connected directly to the
battery positive post.
Does the light illuminate brightly?
