2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   Shift solenoid valve SR connector terminal - Shift solenoid valve SR body	20°C (68°F)	11 to 15 Ω

3. Apply 12 V battery voltage to the shift solenoid valve and check that the valve moves and makes an operating noise.

   OK

   Measurement Condition	Specified Condition
   Battery positive (+) → Shift solenoid valve SR connector Battery negative (-) → Shift solenoid valve SR body	Valve moves and makes operating noise
