CAUTION:
 Make sure that turbine revolution sensor securely installs input speed sensor holes (A).
 Hang down output speed senso r harness toward outside so
as not to disturb installation of the control valve & TCM.
 Adjust A/T assembly harness connector of the control valve
& TCM to terminal hole of transmission case.
 Assemble it so that manual valve (1) cutout is engaged with manual plate (2) projection.
- Install bolts and clip (1) to the control valve & TCM. Tighten bolt (E) to the specified torque before tightening the other than bolts.
*: Reamer bolt
 Refer to the following when installing oil pan to transmission case.CAUTION:
 Clean foreign materials (gear wear particles) that adhere on the inside of the oil pan and on the
magnet, and then assembly.
 Completely remove all moisture, oil and old gasket, etc. from oil pan gasket mounting surface of
transmission case and oil pan.
 Never reuse oil pan gasket and oil pan mounting bolts.
 Install oil pan gasket in the di rection to align hole position.
- Tighten the oil pan mounting bolts to the specified torque in the numerical order as shown in the figure after temporarily tightening
them.
