Transmission and Torque Converter
(ZF 4WG-310)
TRANSMISSION CONTROL VALVE
1. The transmission control valve contains a
temperature sensor and proportional
solenoid valves (Y1 - Y6) that direct
pressurized fluid to various clutches that
generates a speed with control the shift
gears.
2. Specification of the proportional solenoid
valve.
• Resistance: 19 ±1.9 ohm at 20˚C
(68˚F)
• Pressure: 0.8 kg/cm

3. The contained temperature sensor detects
the temperature of the control valve and
transmits the electrical signal to the TCU,
and serves TCU determines gears to
change.
• Neutral: At temperature less than -
30˚C (-22˚F)
• 1st or 2nd gear: At temperature less
than -10˚C (14˚F)
• Normal Operation: At temperature
greater than -10˚C (14˚F)
TRANSMISSION OIL TEMPERATURE
SENSOR
1. Detecting a oil temperature of
transmission and send a control signal to
transmission oil temperature gauge.
2. Specification
• Resistance
216 ±30 Ohm (at 60˚C (140˚F))
81.2 ±10 Ohm (at 90˚C (194˚F))
36.5 ±3.5 Ohm (at 120˚C (248˚F))
18.7 ±2.1 Ohm (at 150˚C (302˚F))
