Scheme 7

Scheme 7: SHIFT SOLENOIDS
ComponentNoteResistance (ohms)
Gear shift solenoid S1, S2Resistance between the solenoid pins and the solenoid casing/transmission housing.+20 °C= 11-16 ohms

Other values, see diagram. When measuring at other temperature than +20 °C the check-measurement shall be performed at +20 °C. This is to ensure if the resistance is correct or not.

Scheme 8

Scheme 8: LINEAR PRESSURE SOLENOID SLT, SLB1, SLC1, SLC2, SLC3 AND LOCK-UP SOLENOID SLU
ComponentNoteResistance (ohms)
Lock-up solenoid (SLU) Line pressure solenoids (SLT), (SLB1),(SLC1),(SLC2),(SLC3)Resistance between solenoid pins.+20 °C= 5.0-5.6 ohms

Other values, see diagram. When measuring at other temperature than +20 °C the check-measurement shall be performed at +20 °C. This is to ensure if the resistance is correct or not.

Scheme 9

Scheme 9: OIL TEMPERATURE SENSOR
ComponentNoteResistance (ohms)
Oil temperature sensorResistance between the temperature sensor terminals.+10 °C = 5620-7310 ohms
+25 °C = 3500 ohms
+110 °C = 220-270 ohms

Resistance decreases with increasing temperature.

A test measurement must be taken at both temperatures. This is to establish if the resistance is correct or not.

Scheme 10

Scheme 10: SOLENOID P-POSITION LOCKOUT
ComponentNoteResistance (ohms)
Solenoid p-position lockoutResistance between the solenoid's connections+20 °C= 24.5 - 29.3 ohms
