Gearbox installation — cars with a 3.2 L FSI engine (Audi A4 B8)

Replace bolts that have been over-tightened. Replace self-locking nuts and bolts, as well as seals. rings, seals and gaskets. cuffs. Secure all hose connections with hose clamps that comply with the applicable standard. When assembling, install all wire harnesses in their places. As a rule, before installing a replacement gearbox, blow out the ATF oil lines and ATF oil cooler with compressed air (max 10 bar). Before installation, be sure to clean the threaded holes in the cylinder block using a tap to remove any deposits. When installing a gearbox from a replacement stock: install the gearbox support, gearbox cushion, and tunnel crossmember on the new gearbox. Install the gearbox on the "T40173" mounting bracket and secure it with harness "1", as shown in the figure. Before connecting the engine and gearbox, carry out the following preparatory actions. Rotate the torque converter so that the hole next to the "arrow" notch is visible in the opening at the bottom of the gearbox housing, as shown in the figure. There is only one notch on the perimeter, so the torque converter should be rotated accordingly.



Install the "T40170" transport protection from below under the gearbox housing and attach it to the shaft with flange "1".





Check the presence of centering bushings "A" for the engine and gearbox in the cylinder block; insert the bushings if necessary. Check the aluminum engine-to-gearbox mounting bolts for reuse and, if necessary, mark them. Attach the gearbox to the engine and tighten bolts "1, 6...11." Remove the "T40170" transport protection.



Fix plug "1" in the hole for the starter. The plug "1" must fit tightly "arrows". Depending on the engine, different versions of the plug are provided. If the starter installation is difficult, lightly lubricate the plug. Install the starter.



Loosen the lead screws "10-222 A/11".





Raise the transmission and tighten the tunnel crossmember "arrow" bolts. Loosen the harness and remove the lift with the "T40173" transmission mount from under the transmission.



The next stage of work is necessary to ensure uniform contact of the torque converter with the driven disk without distortion. Lightly press the torque converter "2" using the mounting. lever "1" from driven disk "3" in the "direction of the arrow".



Tighten the torque converter bolts to the driven disc as follows. Use a 16 mm ring spanner to tighten the bolts "VAG1332/14". Screw in the first "arrow" bolt all the way (2 Nm).





Insert the guide pin of the adapter "T40058" as follows: the large diameter "arrow 1" faces the engine, the small diameter "arrow 2" faces the adapter.



Turn the crankshaft using the adapter "T40058" by 180° in the direction of engine rotation "arrow".



With the crankshaft in this position, tighten the accessible bolt "arrow" to a torque of 60 Nm. Rotate the crankshaft 60° further and tighten the remaining 5 bolts to a torque of 60 Nm.





Tighten the remaining bolts "2...5". Further installation is carried out in the reverse order. taking into account the following. Bolt the steering column to the steering gear. Install the subframe crosspiece. Install the selector cable. Install the ATF lines. Bolt the left and right drive shafts to the transmission. Install the drive shaft heat shields. Install the cardan shaft. Install and secure the system. exhaust gas release without mechanical stress. Installation of noise insulation. Connect the battery. Check and adjust the selector cable. Checking and adjusting the ATF oil level.
