<- : Bolt
ii) Remove bracket (1) from plug (2).





iii) Remove O-ring (1) from plug (2).





13) Remove O-ring from A/T assembly harness connector.





14) Disconnect TCM connectors.





CAUTION:
Do not damage connectors.

15) Remove A/T assembly harness connector from control valve with TCM using suitable tool.





16) Disconnect TCM connector (1) and transmission range switch connector (2).





CAUTION:
Do not damage connectors.

INSTALLATION

CAUTION:
After completing installation, check A/T fluid leakage and fluid level.

1) Connect TCM connector (1) and transmission range switch connector (2).





2) Install A/T assembly harness connector to control valve with TCM.





3) Connect TCM connector.





4) Install new O-ring in A/T assembly harness connector.





CAUTION:
^ Do not reuse O-ring.
^ Apply ATF to O-ring.

5) Install the A/T fluid temperature sensor 2 or plug as shown below.
a) A/T fluid temperature sensor 2
i) Install A/T fluid temperature sensor 2 to bracket.





ii) Install A/T fluid temperature sensor 2 (with bracket) to control valve with TCM. Tighten A/T fluid temperature sensor 2 bolt to the specified torque.





CAUTION:
Adjust bolt hole of bracket to bolt hole of control valve with TCM.

b) Plug

NOTE:
^ When replacing the A/T fluid temperature sensor 2 with the plug, the A/T fluid temperature sensor 2 connector should not be connected.
^ Fold the terminal clips.

i) Install new O-ring (1) in plug (2).





CAUTION:
^ Do not reuse O-ring.
^ Apply ATF to O-ring.
^ O-ring should be free of contamination.

ii) Install plug (2) to bracket (1).





iii) Install plug (1) [with bracket (2)] to control valve with TCM. Tighten plug bolt (<=) to the specified torque.





CAUTION:
Adjust bolt hole of bracket to bolt hole of control valve with TCM.

6) Install control valve with TCM in transmission case.





CAUTION:
^ Make sure that input speed sensor is securely installed into input speed sensor hole (A).
^ Hang down output speed sensor harness toward outside so as not to disturb installation of control valve with TCM.
^ Adjust A/T assembly harness connector of control valve with TCM to terminal hole of transmission case.
^ Assemble it so that manual valve cutout is engaged with manual plate projection.





7) Install bolts (A), (B) and (C) in control valve with TCM.








8) Tighten bolt (1), (2) and (3) temporarily to prevent dislocation. After that tighten them in order (1 -> 2 -> 3). Then tighten other bolts. Tighten control valve with TCM bolts to the specified torque.








9) After installing the A/T fluid temperature sensor 2, connect the A/T fluid temperature sensor 2 connector as shown below.
a) Connect A/T fluid temperature sensor 2 connector (A).





b) Securely fasten terminal cord assembly and A/T fluid temperature sensor 2 harness with terminal clips.
10) Connect output speed sensor connector (1).





11) Securely fasten output speed sensor (1) harness with terminal clip.





12) Install oil pan to transmission case.
13) Pull up A/T assembly harness connector.





CAUTION:
Do not damage connector.

14) Install snap ring to A/T assembly harness connector.





15) Connect A/T assembly harness connector.
16) Connect the negative battery terminal.
17) Refill the A/T with fluid and check the fluid level and for fluid leakage.
