Before disconnecting the battery, please read the following

1. Determine the correct coding for the anti-theft radio
2. Turn ignition OFF.
3. Disconnect battery ground cable.
4. After reconnecting the battery cable, the ECM "Basic Setting" must be re-established using the VAG 1551 scan tool, or equivalent aftermarket scan tool.
5. In the initial learning phase after establishing basic setting, engine idle and driveability may be affected. In this case, let the engine run at idle for a few minutes until the learning process is completed.

Before disconnecting the battery, please read the following

1. Determine the correct coding for the anti-theft radio
2. Turn ignition OFF.
3. Disconnect battery ground cable.
4. On vehicles equipped with Audi Telematics by OnStar, switch-off the emergency (back-up) battery for the Telematic/Telephone Control Module prior to disconnecting vehicle battery. After reconnecting vehicle battery on vehicles equipped with Audi Telematics by OnStar, switch-on the emergency (back-up) battery for the Telematic/Telephone Control Module. The emergency (back-up) battery is mounted behind the Telephone/Telematic Control Module (under rear parcel shelf). (Scheme 94)

5. Place holding device (10-222A) with adapter for holding device (10-222A/4) (D) on bolts of strut mount. (Scheme 97) Threaded spindle (B) must face forward, and threaded spindle (C) must face rearward.
6. Disconnect fuel line from pressure regulator (arrow). (Scheme 98)
7. Install holding device (3180) in holding eyes, from transmission side, and tighten. (Scheme 97) Install additional hooks (10-222 A/2) in holding eyes (A) near pressure regulator. Take up weight of engine slightly using spindles (B and C).
8. Remove noise insulation. (Scheme 100)
9. Unclip air duct for generator. Remove heat shields for left and right axle shafts (arrows). (Scheme 101) Remove axle shafts from transmission flanges.
10. Loosen dual clamp and remove front exhaust pipes together with heated oxygen sensors and three way catalytic converters. Remove heat shield (B) for drive shaft from cover for drive shaft (arrows). (Scheme 102)
11. Place mating marks on driveshaft and transmission mating flanges for reassembly reference. Disconnect drive shaft from transmission and wire aside.
12. Remove lower mounting bolts (arrows) from engine mounts. (Scheme 103)
13. Remove right front torque arm mounting bolts (arrows). (Scheme 104) Using spindles, raise engine until engine mount comes out of subframe.
14. Remove lower mounting bolts between engine oil pan and transmission. Remove right engine support and cable clamps (arrows). (Scheme 105) Place engine mount on subframe.
15. Remove remaining mounting bolts from starter and bracket (arrows). (Scheme 106) Turn starter outward slightly. Remove positive cable (1). (Scheme 107) Disconnect wire (2). Pull starter outward, and remove.
16. Counterholding center bolt on vibration damper, remove bolts for torque converter through opening for starter. Turn crankshaft 1/3 revolution further for each bolt. (Scheme 108)
17. Lower engine and install left engine mount on subframe, tightening lower mounting bolts slightly. Remove rear noise insulation bracket (1). (Scheme 109) Move safety lever (4), and disconnect transmission wiring harness connector. Disconnect multi-function switch connector (2), and disconnect bracket for connector (3).
18. Disconnect speedometer vehicle speed sensor (G22). Remove engine speed (RPM) sensor (G28) from left front of transmission. Remove multi-function switch.
19. Press ball socket of selector lever cable (1) from transmission selector lever (2). (Scheme 110) If necessary, mark position of bracket for selector lever cable on transmission case for re-installation. (Scheme 111)
20. Disconnect holding clamp for ATF lines from left engine mount. Place oil pan underneath transmission. Disconnect ATF lines from transmission. Pull out lines and set aside.
21. Install transmission support 3282 with adjustment plate (3282/25) and install on engine/transmission jack (V.A.G. 1383 A). Support transmission with jack (V.A.G. 1383 A) and transmission support (3282) from below. see scheme 22 Left support (arrow) must be attached securely with M10 bolt.
22. Remove left and right side transmission support, complete with transmission mounts. see scheme 23
23. Remove bolts (1 and 2). see scheme 24 Lower rear subframe a maximum of 3.94" (100 mm), from mounting point on body, by releasing tension on engine support.
24. Lower rear of transmission a small distance. Support engine at front with commercial support. see scheme 25 Remove remaining engine/transmission connecting bolts.
25. Using a pry bar, press torque converter off flex plate of engine. see scheme 26 Press transmission off engine.

1. Installation is reverse of removal procedure. Note the following points. Before installing transmission, ensure torque converter is properly inserted in transmission. See step 2. Before installing transmission, ensure dowels (A and B) are properly installed in engine housing. see scheme 28 Take care not to catch any loose wiring or hoses between engine and transmission. Fasten torque converter to drive plate using NEW bolts (M10x1x17). If necessary, slide shim plate between front longmember and torque arm. Always replace self locking bolts and nuts. Always replace gaskets and "O" rings. Always REPLACE M14 bolts and lock washers at engine and transmission carrier (subframe).
2. Insert torque converter through seal to first stop on transmission shaft. Press and rotate torque converter by hand until recess of torque converter hub engages in driver of pump gear and torque converter is felt to slip into proper position.
3. Torque converter is correctly installed when distance between flange of bell housing and threaded plates at converter is approximately 22 mm. see scheme 29 If converter was not properly installed, dimension is approximately 10 mm.
4. Install subframe. Always replace subframe bolts and washers. Tighten bolts to specification. See «TORQUE SPECIFICATIONS»(/audi/a8/d3-2002-2005/remont/automatic-trans/#removal-installation-at-01l-awd__torque-specifications). If necessary, perform wheel alignment after installing transmission. See «SPECIFICATIONS & PROCEDURES»(/audi/a8/d3-2002-2005/remont/wheel-alignment/#specifications-procedures) article in SUSPENSION.

TORQUE SPECIFICATIONS

TORQUE SPECIFICATIONS

Note. Engine-to-transaxle tightening torques are valid only for nuts and bolts that are lightly greased, oiled, covered with a thin coat of phosphate or blackened. Other lubricants are permitted (e.g. engine oil or transaxle fluid); however, they may not contain graphite. Do not use any degreased parts.
