00 GENERAL, TECHNICAL DATA > GENERAL INFORMATION > SAFETY PRECAUTIONS > If testing equipment must be used during a road test, observe the following: WARNING: Distraction and testing equipment that is not secured properly can cause accidents. The passenger airbag could pose a risk if it deploys in a collision. Operating testing equipment while driving causes it to shift position. There is an increased risk of injury due to unsecured testing equipment. Always secure testing equipment on the rear seat using a strap and have a second person in the rear seat operate it. Observe the following to avoid personal injury and vehicle damage: WARNING: There is a risk of injury and accident from accidentally engaging a gear when the engine is running. Before performing work with the engine running, place the selector lever in the "P" position and set the parking brake. Observe the following to prevent personal injury and/or damage to the electrical/electronic components: Connect and disconnect test equipment only when the ignition is turned off. CAUTION: Danger of causing damage to electrical and electronic components. Be sure to follow the procedure for connecting the battery and afterwards.

Refer to BATTERY, DISCONNECTING AND CONNECTING . 00 GENERAL, TECHNICAL DATA > GENERAL INFORMATION > CONTACT CORROSION > Contact corrosion can occur if non-approved fasteners are used on the vehicle (bolts, nuts, washers, etc.). For this reason, only connecting elements with a special surface coating are installed. In addition, rubber or plastic parts and adhesive are made of materials that do not conduct electricity. If you are not sure about the suitability of parts, install new parts. Note: We recommend using original replacement parts only. They have been inspected and are compatible with aluminum. It is recommended to use Audi accessories. Damage resulting from contact corrosion is not covered by the warranty. 00 GENERAL, TECHNICAL DATA > GENERAL INFORMATION > CLEAN WORKING CONDITIONS > Always clean connection places and surrounding areas with engine or brake cleaner before loosening and dry the cleaned places. Clean the transmission and transmission components using cleaning solution -D 009 401 04-. Use lint free cloths when cleaning, for example, the "WYPALL X70/WORKHORSE" cloth made by Kimberly-Clark Professional. Seal all open lines and connections immediately with clean plugs or caps from the engine bung set VAS 6122. Place removed parts on a clean surface and cover. Only use lint free cloths for this! Carefully cover or seal unpacked components if repairs cannot be performed immediately. Only install clean components: Remove the replacement parts from their packaging just prior to installing them. Protect the disconnected connectors from dirt and moisture and only connect them when they are dry. 00 GENERAL, TECHNICAL DATA > GENERAL INFORMATION > GENERAL REPAIR INFORMATION > The maximum possible care and cleanliness and proper tools are essential to ensure satisfactory and successful transmission repairs. The usual basic safety precautions also, naturally apply when carrying out vehicle repairs. Some general repair information that applies to several procedures is summarized here. They apply to this repair information.

Special Tools and Equipment For a complete list of special tools used in the repair information, refer to "Special Tools and Equipment" in Service Net. Selector Mechanism Emergency Release If the battery has been disconnected or is discharged and the vehicle must be towed or pushed, it will be necessary to push the selector mechanism emergency release to shift the selector lever from "P" to "N". Refer to SELECTOR MECHANISM, PERFORMING EMERGENCY RELEASE . Transmission Clean working conditions for the automatic transmission. Refer to CLEAN WORKING CONDITIONS . Do not let the engine run or tow the vehicle when the oil pan is removed or when there is no Automatic Transmission Fluid (ATF) in the engine. With the transmission removed, secure the torque converter so that it cannot fall out. Check the installed dimension of the torque converter before installing the transmission. Refer to TORQUE CONVERTER, INSTALLING => Installed Dimension . When installing the transmission, make sure that the alignment bushings are correctly installed. When exchanging the automatic transmission or components, all fluid levels should be checked and corrected, as necessary. Also, all transmission fluid lines must be cleaned. Capacities, refer to CAPACITIES , specifications O-rings, Shaft Seals and Seals O-rings, shaft seals and seals must be replaced. After removing seals, examine the contact surface on the housing/shaft for burrs resulting from removal or for other signs of damage. Before installing a radial shaft seal, fill the space between the sealing lips -arrow- halfway with sealing grease for seal G 052 128 A1.

The open side of the shaft seal point toward the fluid to be sealed in. Before installing, lightly lubricate the shaft seal outer circumference and sealing lips with ATF or gear oil, depending on installed location. Lubricate the O-rings with ATF before inserting to prevent crushing them. Always only use approved ATF. Other types of lubrication cause faults to occur in the transmission hydraulics. Press in a new shaft seal, so that the sealing lip does not run on the same point as the sealing lip of the old shaft seal (use insertion depth tolerances). Replace paper gaskets, thoroughly clean sealing surfaces and completely remove old seals. After installing, check the relevant fluid levels and top off as necessary. Capacities, refer to CAPACITIES , specifications, Bolts and Nuts Loosen bolts in the opposite direction of the tightening sequence if another sequence is not specified. Nuts and bolts which secure covers and housings should be loosened and tightened crosswise in stages if no tightening sequence is specified. The tightening specifications stated apply to non-lubricated nuts and bolts. Always replace the self locking nuts and bolts. Clean threads of bolts that were applied with locking fluid using a wire brush. Install the bolts with liquid locking fluid AMV 185 101 A1. Threaded holes into which self locking bolts or bolts coated with locking fluid are installed, must be cleaned (for example, with a tap). Otherwise there is a risk that the bolts will shear the next time Fig 1: Identifying Oil Seals Sealing Lips Courtesy of AUDI OF AMERICA, LLC

they are removed. Circlips Do not overstretch the circlips. Always replace damaged or stretched circlips. The circlips must fit completely inside the groove. Bearings Insert bearing with axle oil or ATF, depending on the installed location. Replace the transmission if any of the shift elements are scorched. Control Modules, Electronic Components and Contacts Only touch electrical components after discharging static electricity on a grounded object, for example, by touching (skin contact) vehicle or vehicle lift. Connector contacts in connectors, control modules and electrical components must not be touched with the hands under any circumstances. They can be destroyed by static discharge. Guided Fault Finding, On Board Diagnostic (OBD) and Test Instruments Try to determine the exact cause of the fault using the Guided Fault Finding , Vehicle Self- Diagnosis and Test Instruments before starting any work on the automatic transmission, refer to Vehicle diagnosis, testing and information system VAS 5051. 00 GENERAL, TECHNICAL DATA > GENERAL INFORMATION > TOWING > CAUTION: When towing, the selector lever must be in the "N" position and the vehicle must not be towed for more than 50 km or at a speed in excess of 50 km/h, otherwise the transmission can get damaged. NOTE: "Tow-starting" the engine, for example, when the battery is too weak or the starter is defective, is not possible. 00 GENERAL, TECHNICAL DATA > GENERAL INFORMATION > TRANSMISSION IDENTIFICATION > The "6 Spd. Automatic Transmission 09D" is installed in the Audi Q7. For the correct allocation, refer to CODE LETTERS, TRANSMISSION ALLOCATIONS, RATIOS AND EQUIPMENT . Transmission code letters are located on the type plate on the left side of the transmission at the bottom.
