4-unit solenoid assembly (Line pressure solenoid, lock-up solenoid and shift solenoids A and B)
- Check that filter is not clogged or damaged (line pressure solenoid and lock-up solenoid).
- Measure resistance of each solenoid
Solenoids A & B 20 - 40 ohms
Lock-up Solenoid 10 - 20 ohms
Line Pressure Solenoid 2.5 - 5 ohms




Fluid temperature sensor
Measure resistance 2.5 ohms at 20°C
0.3 ohms at 80°C
