Use an ohmmeter to measure the resistance between the transmission connector and the end of the appropriate solenoid cable. Shake the harness gently during the measurement to identify any possible loose connections. The ohmmeter should read 0 Ω .

Terminal	Solenoid	Terminal	Solenoid
21	S1/white	24	STH/brown
22	S2/black	25	STH/, ground/blue
23	SL/red	-	-

Replace the cable harness if the ohmmeter reading shows another value. See below.
