-- Ensure no lines are kinked when sliding engine and transmission together.

-- Always use new bolts to secure the torque converter to the drive plate.

Note the following when installation the transmission.

CAUTION:

Before and during fastening the engine/transmission flange bolts, check that the torque converter can still be turned behind the drive plate. If the torque converter cannot be turned, it must be assumed that it has not been installed properly and that the drive plate of the torque converter or the ATF pump will be destroyed during final tightening of the bolts.

-- Attach the transmission to the engine.

-- Turn the crankshaft 120° in direction of engine rotation and install the torque converter bolts through the opening for the starter and tighten them hand-tight.

NOTE:

The tightening specifications apply only to lightly greased, oiled, phosphated or blackened nuts and bolts.

Additional lubricant such as engine oil or transmission fluid may be used, but do not use graphite lubricant.

Do not use any ungreased parts.

Tightening specification tolerance +/- 15%.
