Automatic Transmission (Aw30-40LE): Solenoid: Inspection: Notes

Resistance check
- Using an ohmmeter, check the resistance between each terminals (S1/S2/SL) and body.
  1. Solenoid S1, S2 and lock-up solenoid SL resistance: 11 - 15 Ω (at 20°C) (Reference) 12 - 16 Ω (at 40°C)
- Using an ohmmeter, check the resistance between each terminals (STH) and (STHG).
  1. Pressure control solenoid resistance: 5 - 5.6 Ω (at 20°C) (Reference) 5.4 - 6.1 Ω (at 40°C)

NOTE: If the pressure control solenoid resistance is not within specification, replace the valve body assembly.
Operation check
Check the solenoid operation by blowing into an oil hole as shown in Figure and Figure .
