Turn ignition switch OFF.
Disconnect the solenoid valve connector (A).
Measure resistance between sensor signal terminal and sensor ground terminal.
Check that the resistance is within the specification.
Remove the air cleaner assembly.
(Refer to Engine Mechanical System - "Air cleaner")
Remove the under cover (A).
Remove the drain plug (A) and reinstall the drain plug after draining ATF totally.
Tightening torque:
38.2 ~ 48.1 N.m (3.9 ~ 4.9 kgf.m, 28.2 ~ 35.4 lb-ft)
The gasket of the drain plug use new one.
Remove the wiring mounting bolt (A).
Tightening torque:
(A) 9.8~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
Remove the resonator (A).
Remove the valve body cover (B) after removing a air breather hose (A) from the valve body cover.
Tightening torque:
11.8 ~ 13.7 N.m (1.2 ~ 1.4 kgf.m, 8.7 ~ 10.1 lb-ft)
Remove the solenoid valve main connector (A) and oil temperature sensor (B) after removing the bolts.
Tightening torque:
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
Remove the solenoid valve support bracket (B) and the valve body mounting bolt (A-1ea).
Tightening torque :
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
Remove the torque converter control solenoid valve (A).
Installation is the reverse of removal.
Adding Automatic Transaxle Fluid(ATF).
(Refer to Hydraulic System - "Fluid")
Perform Transaxle Control Module(TCM) learning after replacing the valve body to prevent slow transaxle response, jerky acceleration and jerky startup.
(Refer to Automatic Transaxle Control System - "Repair procedures")
Use new valve body gasket (A).
