ATF Temperature Sensor Test/Replacement

1.Remove the drain plug (A), and drain the automatic transmission fluid (ATF).

 

2.Reinstall the drain plug with a new sealing washer (B).

3.Place the transmission jack under the transmission, and lift it up to create clearance between the transmission and front sub-frame.

4.Disconnect the shift solenoid harness connector.

5.Remove the bolt (A) securing the bracket (B) of the ATF cooler inlet line (C) on the shift solenoid valve cover (D), and remove the line bolt (E) with sealing washers (F).

 

6.Remove the shift solenoid valve cover, gasket (G), and dowel pins (H).

7.Remove the bolt (A), and remove the shift solenoid harness connector (B).

 

8.Measure ATF temperature sensor resistance between the No. 6 and No. 7 terminals of the shift solenoid harness connector.

STANDARD: 50 W-25 kW 

9.If the resistance is out of standard, replace the ATF temperature sensor. The ATF temperature sensor is not available separately.

10.Disconnect the connectors from the shift solenoid valves.

11.Connect the shift solenoid valve A connector with the ATF temperature sensor (F) on the new solenoid harness.

 

12.Connect the solenoid valve B connector (ORN wire), solenoid valve C connector (GRN wire), and solenoid valve E connector (RED wire).

13.Install the new O-ring (G) on the shift solenoid harness connector (H), and install the connector in the transmission housing.

14.Install the shift solenoid valve cover with the new gasket and dowel pins.

15.Install the ATF cooler inlet line with the line bolt and the new sealing washers. Create clearance with the jack between the transmission and the front sub-frame to tighten the line bolt with the torque wrench.

16.Install the bracket of the ATF cooler inlet line on the shift solenoid valve cover with the bolt.

17.Check the connector for rust, dirt, or oil, then connect the connector securely.

18.Remove the transmission jack.

19.Refill the transmission with the recommended fluid.
