Component  Remarks  Resistance (Ω) 
Lock-up solenoid (SLU)
Linear pressure solenoid (SLT) (SLS)
Resistance between the solenoid pins +20°C = 5.0-5.6 Ω

For other values, see diagram. When taking readings at temperatures other than +20°C, a control reading must be taken at +20°C. This is done to check whether the resistance is correct or not.
