Procedure

NOTE:

Replace any bolts that were tightened with an additional turn.

Replace self-locking nuts and bolts and seals, gaskets and O-rings.

Only remove the plugs or caps after installing the lines.

The hose connections as well as the air guide pipes and hoses must be free of oil and grease before installing.

Secure all hose connections with hose clamps of the same type as those equipped by the factory .

To mount the air guide hoses on their connectors securely, spray the bolts on the used clamps with rust remover before installing.

When installing, bring all cable ties back to same positions.

-- Clean the threaded holes in the cylinder block for connecting the engine and transmission using a thread tap before installing the transmission.

-- Install the engine support and engine mount, refer to SUBFRAME MOUNT OVERVIEW .

-- The following preparations must be made before connecting the engine and transmission

-- Turn the torque converter so that hole next to the notch -arrow- is visible in the lower cut-out in the transmission housing as illustrated.

NOTE:

There is only 1 notch on the circumference; rotate the torque converter as needed.

-- Insert the Clutch Module Transportation Lock T40170 in the transmission housing from below and secure it on the flange shaft -1-.

-- When joining the engine and subframe, hold the ATF lines in their installation position.

-- Check if the alignment sleeves -A- for centering the engine/transmission are in the cylinder block and insert them if they are not.

-- Inspect the aluminum bolts used to connect the engine to the transmission to see if they can be used again and mark them, if necessary, refer to [For transmission(s) 0BK] Transmission, Removing and Installing .

-- Position the transmission on the engine. Be careful of the starter.

-- Tighten bolts -1 to 11-.
