      NOTE:
      • Make sure that the mark is positioned as shown in the illustration.
      • Do not use excess force to pry on the automatic transmission assembly.
  5. INSTALL DRIVE PLATE AND TORQUE CONVERTER SETTING BOLT 
    1. Turn the crankshaft to gain access to the installation locations of the 6 torque converter setting bolts and install each bolt while holding the crankshaft pulley bolt with a wrench.

      Torque: 48 N*m (489 kgf*cm, 35 ft.*lbf) 

      NOTE:

      First install the black-colored bolt, and then the remaining 5 silver colored bolts.
