Procedure
• Replace bolts that are tightened to the specification. The aluminum bolts for attaching the engine to the manual transmission may be used two times.
• Replace self-locking nuts and bolts and seals, gaskets and O-rings.
• Secure all hose connections with hose clamps of the same type as those equipped by the factory, refer to the Parts Catalog.
• When installing, bring all cable ties back to the same positions.
Transmission installation tightening specifications.
- Mount the transmission onto the (T40173) and secure it using the tension strap - 1 - as illustrated.
- Check the input shaft near the bearing in the drive plate - arrow - for scoring. Replace the needle bearing in the drive plate if necessary.
- Check if the alignment sleeves - A - for centering the engine/transmission are in the cylinder block and insert them if they are not.
• See if it is possible to use the aluminum bolts - 2 through 11 - again and mark them if necessary.
- Installing the clutch module if necessary.
- The following preparations must be made before connecting the engine and transmission:
- Insert the (T40169) in the transmission housing and the clutch module from below as shown in the illustration.
• The (T40169) must engage in the semi-circular opening - 1 - and into the check hole - 2 -.
• There is only 1 inspection opening on the circumference. Rotate the clutch module as needed.
- Install the bolts from the assembly device into the holes on the transmission housing.
- Insert the (T40170) in the transmission housing from below and secure it on the flange shaft - 1 -.
- Raise the transmission straight up until the clutch slave cylinder - 1 - can be inserted.
- Tighten bolt - 2 -. Tightening specification - item 17 - => [ (Item 17) Bolt ] Removal and Replacement.
• The next step is only necessary if a drive plate with alignment pins - 2 - is installed.
- Align the drive plate to the clutch module so the alignment pins - 2 - on the drive plate (if applicable) can engage in the larger holes - 1 - on the clutch module.
The clutch will not function properly if it is not installed correctly.
• The clutch may have noticeable function problems if the alignment pins for the drive plate - 2 - are not in the holes in the clutch module - 1 -.
- Connect the transmission to the engine and tighten - 3.... 11 - the bolts. Tightening specifications.
- Insert the starter and tighten the bolt - 3 - manually from the engine side out.
- Install the spacer sleeve - 2 - between the starter and transmission, push the bolt - 1 - through and tighten.
- Tighten the starter bolts - 1 and 3 -. Tightening specifications.
- Raise the transmission using the (V.A.G 1383 A) until dimension - a - is reached between the subframe and the body.
• - a - = minimum 80 mm
- Attach the push rod - 1 - - item 27 - => [ (Item 27) Bolt ] Selector Mechanism Overview.
- Attach the connecting rod - 3 -. Tightening specification - item 25 - => [ (Item 25) Bolt ] Selector Mechanism Overview.
- Connect the connector - 2 - to the transmission range gear recognition switch (F208) or the gear recognition sensor (G604).
Install the transmission shift lever - 2 - as follows:
• The gearshift lever - 2 - can be attached to the gearshift shaft - 1 - in only one position (gap in the splines - arrow -).
- Tighten the selector lever. Tightening specification - item 18 - => [ (Item 18) Nut ] Selector Mechanism Overview.
- Connect the connector to the transmission neutral position sensor (G701) - 1 -.
- Loosen the (10 - 222 A /11).
- Lift the transmission further and tighten the bolts - arrows - on the tunnel crossmember. Refer to => [ Tunnel Crossmember, Transmission Mount and Transmission Support Overview ] Tunnel Crossmember, Transmission Mount and Transmission Support Overview.
- Remove the (V.A.G 1383 A) and (T40173).
- Attach the left and right drive axles to the transmission flange shafts.
- Install the driveshaft heat shield. Refer to => [ Drive Axle Heat Shield - Tightening Specification ].
- Install the subframe shield on the left and right side.
- Secure the driveshaft on the transmission.
Block the driveshaft. To do this, place the (T10172) and (T10172/5) on the driveshaft bolts on the transmission or the rear final drive.
Tightening Sequence - Clutch Module to the Drive Plate
- Remove the (T40169) and (T40170).
- Remove the gearshift shaft - 1 - and then move the gearshift lever - 2 - forward in direction of - arrow - into 6th gear.
• The following step is absolutely necessary to make sure the clutch module rests on the drive plate evenly and is not tilted.
- Turn both front wheel together in one direction until the clutch module turns one complete turn (360°).
• The check hole - arrow - must be visible in the transmission housing cut-out.
Tighten the clutch module to the drive plate as follows:
• Use new bolts.
• Tighten the bolts using the (V.A.G 1332/14).
- Install the first bolt - arrow - and tighten by hand (2 Nm).
- Rotate the clutch module 120° further in the direction of engine rotation with the front wheels and install the second bold and tighten by hand (2 Nm).
- Rotate the clutch module 120° in the direction of engine rotation again.
- Install the third bolt and tighten it.
- Tighten the remaining two bolts.
Install in reverse order of removal. Note the following:
- Install the driveshaft heat shield - A - and tighten the bolts - arrows - to 25 Nm, if equipped.
- Install the exhaust system so that it is free of tension.
Vehicles with Transmission Fluid Heater
- Connect the coolant hoses to the connections on the transmission and secure them with the spring clamps - 1 -.
- Remove the (3094).
- Fill with coolant.
All Vehicles
- Attach the steering intermediate shaft to the steering gear.
- Install the subframe crossbrace.
- Gear oil level in manual transmission, checking. Refer to => [ Transmission Fluid Level, Checking ] Service and Repair.
- Install the noise insulation.
- Complete the steps required after connecting the battery.
Danger of causing damage to the control modules due to the excess voltage.
• Do not use a charger to jump start!
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%.
Drive Axle Heat Shield - Tightening Specification
- Tighten the heat shield bolts - arrows - to 23 Nm.
Securing the Engine to the Manual Transmission
• Audi A4 from VIN 8K-9-066500 and Audi A5 from VIN 8T-9-008000: The aluminum bolts - 2 through 11 - may be used twice. Therefore, the bolts must be marked with two notches "X" made by a chisel after they have be 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.
• Audi A4 through VIN 8K-9-066499: Always replace the aluminum bolts.
• Audi A5 through VIN 8T-9-007999: Always replace the aluminum bolts.
