4. Install and tighten transmission support. For details, see -> 373519 Removing and installing transmission - section on "Installing"
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 ftlb.) ; exhaust clamp => Tightening torque: 23 Nm (17 ftlb.) ; main catalytic converter to transmission support=> Tightening torque: 23 Nm (17 ftlb.) ; main catalytic converter to body => Tightening torque: 23 Nm (17 ftlb.)
