Transmission Installation Tightening Specifications:.
- Before installing a replacement transmission, always clean out the ATF cooler and ATF pipes using compressed air (maximum 10 bar). Refer to => [ Automatic Transmission Fluid Lines, Cleaning ] Service and Repair.
- Clean residue from the threaded holes in the cylinder block using a thread tap before installing.
- When installing a replacement transmission: Install the transmission support, transmission mount and tunnel crossmember in the new transmission. Refer to => [ Tunnel Crossmember, Transmission Mount and Transmission Support Overview ] Tunnel Crossmember, Transmission Mount and Transmission Support Overview.
- Mount the transmission onto the (T40173) and secure it using the tension strap - 1 - as illustrated.
Installing the torque converter incorrectly can cause damage to the ATF pump drive plate.
• Check the installed dimension of the torque converter. Refer to => [ Torque Converter ] Torque Converter.
- 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.
- The following preparations must be made before connecting the engine and transmission:
- Turn the torque converter so that the hole next to the notch - arrow - is visible in the lower cut-out in the transmission housing as illustrated.
• There is only 1 notch on the circumference; rotate the torque converter as needed.
- Insert the (T40170) in the transmission housing from below and secure it on the flange shaft - 1 -.
- 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.
- Attach the transmission to the engine and the tighten the bolts - 1 and 6 through 11 -.
- Remove the (T40170).
- Lift the transmission and tighten the bolts on the tunnel crossmember. Refer to => [ Tunnel Crossmember, Transmission Mount and Transmission Support Overview ] Tunnel Crossmember, Transmission Mount and Transmission Support Overview.
- Loosen the tension strap and remove the (V.A.G 1383 A) with the (T40173) from under the transmission.
• The following step is necessary to make sure the torque converter rests on the drive plate evenly and is not tilted.
- Press the torque converter - 2 - against the drive plate - 3 - slightly in the direction of the - arrow - using an assembly lever - 1 -.
- Attach the torque converter to the drive plate as follows:
• Use the (V.A.G 1332/14) to tighten.
- Install the first bolt - arrow - and tighten by hand (2 Nm).
- Continue turning the crankshaft 180° in the direction of the engine rotation using the (T40058) - arrow -.
- With the crankshaft in this position, tighten the bolt - arrow - to 60 Nm.
- Continue turning the crankshaft 60° and tighten the remaining 5 bolts to the tightening specification.
- Tighten the remaining engine/transmission connecting bolts.
Install in reverse order of removal paying attention to the following:
- Install selector lever cable. Refer to => [ Selector Lever Cable ] Service and Repair.
- Attach the steering intermediate shaft to the steering gear.
- Attach the left and right drive axles to the transmission flange shafts.
- Install the drive axle heat shields. Refer to => [ Drive Axle Heat Shields - Tightening Specification ].
- Install the ATF pipes to the ATF cooler. Refer to => [ ATF Cooler and ATF Pipes Overview ] Description and Operation
- Install the exhaust system.
• Check the vehicle data label or the designation on the rear final drive itself to determine which one is installed in the vehicle. Then select the correct rear final drive repair manual.
- Install the driveshaft.
- Install the right coolant pipe on the transmission.
- Install the noise insulation.
- Connect the battery.
There is a risk of destroying control modules with excess voltage.
• Do not use a charger as a starting aid.
- Check the selector lever cable and adjust if necessary. Refer to => [ Selector Lever Cable, Adjusting ] 0BKA Automatic Transmission.
- Check the ATF level and correct if necessary. Refer to => [ ATF, Checking Level and Correcting ] ATF, Checking Level and Correcting.
Tightening Specifications
• The tightening specifications apply only to lightly greased, oiled, phosphated or blackened nuts and bolts.
• Additional lubricant such as engine or transmission oil may be used, but do not use graphite lubricant.
• Do not use any ungreased parts.
• Tightening specification tolerance +/- 15%.
Other tightening specifications:
Drive Axle Heat Shields - Tightening Specification
• The right drive axle is shown in the illustration.
- Tighten the heat shield bolts - arrows - to 23 Nm.
Transmission Mount for the 3.0 liter TFSI
• The aluminum bolts may be used two times. Therefore, the bolts must be marked with two notches "X" made by a chisel after they have been used the first time - arrow -.
• To prevent damaging the bolts when marking them, do not clamp them in a vise. Insert the bolt using a 14 mm socket with a 1/2 drive, which is inserted in to the vise, as illustrated.
• Bolts marked with an "X" may not be used again.
