INSPECTION
Installation and Inspection of Torque Converter
• After inserting the torque converter to the transmission, check
dimension "A" to ensure it is within the reference value limit.
INSTALLATION
Installation is in the reverse order of removal.

• After converter is installed to drive plate, rotate crankshaft several turns and check to be sure that
transmission rotates freely without binding.
• When tightening the bolts for the torque converter while securing the crankshaft pulley bolt, be sure
to confirm the tightening torque of the crankshaft pulley bolt. Refer to
EM-185, "Removal and Installation"
(VK56DE).
When installing transmission to the engine, tighten the bolts to the specified torque as shown.
• For VQ40DE
• For VK56DE
