4. Install and tighten transmission support. For details, see → Installing Transmission
5. Fit holder for catalytic converter on transmission support.
6. Tighten all screws to the correct torque. Main catalytic converter to primary catalytic converter → Tightening torque: 23 Nm (17 ft lbs.);  exhaust clamp → Tightening torque: 23 Nm (17 ft lbs.);  main catalytic converter to transmission support → Tightening torque: 23 Nm (17 ft lbs.);  main catalytic converter to body → Tightening torque: 23 Nm (17 ft lbs.)
