Installing

NOTE:

Replace bolts which have been tightened to an additional torque.

Replace self-locking nuts and bolts as well as sealing rings, seals and O-rings.

To secure torque converter to the drive plate, use new original bolts. Refer to parts .

Always clean threaded bores in transmission flanged shaft for driveshaft of locking fluid residue using a tap before installation.

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 appropriate for the model. Refer to parts. .

In order to be able to securely mount the air guide hoses on their connectors, spray the screws on the previously used clamps with a rust remover.

During installation, all cable ties must be installed at the same location.

-- Install the left and right engine supports.

-- Check whether fitting sleeves for centering engine and transmission in cylinder block are present, insert missing fitting sleeves.

Installation dimension for torque converter, checking.

CAUTION:

Risk of destroying ATF pump coupling plate by inserting torque converter incorrectly.

Check torque converter installation dimension.

When torque converter is installed correctly, distance -a- between contact surface of threaded holes at torque converter and contact surface of bell housing on automatic transmission is at least 19 mm.

-- Install intermediate plate between engine and transmission onto alignment bushings.

CAUTION:

Risk of destroying transmission due to torque converter inserted incorrectly.

Keep checking whether the torque converter behind the drive plate can be turned before and during tightening of the bolts at engine/transmission connection.
If torque converter cannot be rotated, the ATF pump coupling plate and therefore the transmission are destroyed when connections are tightened to final torque.

-- Position the transmission on the engine and tighten the bolts -3 through 10-.
