IDENTIFICATION

TRANSMISSION APPLICATION

Transmission code letters are located on the data plate under the transmission (arrow). (Scheme 206)

There is another identical data plate on side of transmission which is not accessible with the transmission installed.

Scheme 206

Transmission serial number (arrow 1), Transmission identification (arrow 2), Code letter (arrow 3). (Scheme 207)

Scheme 209

TORQUE CONVERTER

The torque converter is equipped with a lock-up clutch. The lock-up clutch is closed load- and speed-dependent with minimum pulsations and mechanically drives all forward gears independent of slip.

The 5-speed automatic transmission 01V is equipped with 5 hydraulically activated forward gears. By passing the torque converter slip, these forward gears become mechanically driven gears if the lock-up clutch is closed.

ON BOARD DIAGNOSTIC (OBD)

Before performing service work on the automatic transmission, cause of damage must be exactly determined via "Guided Fault Finding".

"Guided Fault Finding" is performed using the VAS5051 tester.

TRANSMISSION CONTROL MODULE (TCM) -J217- WITH DRIVING SITUATION SHIFTING (FUZZY LOGIC)

Driving situation- and driving resistance dependent shift point determination is performed automatically.

Advantages

1. it is shifted depending on consumption.
2. highest engine performance is always available.
3. individual adaptation of shift points in all driving situations.
4. Arbitrarily changed shift points.

SHIFT POINT CHANGE WHEN DRIVING UP- OR DOWNHILL RANGES

At uphill or downhill ranges, the shifts are automatically selected dependent on the accelerator pedal position and vehicle speed via additional shift characteristics maps.

1. Shift characteristics map for extreme uphill driving is adapted to the engine performance.
2. Shift characteristics map for extreme downhill driving is adapted to the braking effect of the engine.

SERVICING NOTES

The maximum possible care, cleanliness and proper tools are essential to ensure satisfactory and successful transmission repairs. The usual basic safety precautions also apply when carrying out vehicle repairs.

1. Rules of cleanliness for working on automatic transmissions. See «Rules Of Cleanliness For Working On Automatic Transmissions»(/audi/a4/b6-2000-2006/remont/automatic-trans/#automatic-transmission-overhaul-01v__rules-of-cleanliness-for-working-on) .
2. Do not run engine with the oil pan removed or without ATF filling and do not tow vehicle.
3. Clean ATF lines and ATF cooler when replacing automatic transmission. See «SERVICING - A/T (01V - WITH 1.8L & 3.0L)»(/audi/a4/b6-2000-2006/remont/automatic-trans/#servicing-at-01v-with-18l-30l) article.
4. Secure torque converter on removed transmission to keep it from falling out.
5. Thoroughly clean all connections and the surrounding area before disconnecting.
6. Check installation dimension of torque converter before installing transmission. See «TORQUE CONVERTER, INSTALLING»(/audi/a4/b6-2000-2006/remont/automatic-trans/#automatic-transmission-overhaul-01v) .
7. When installing transmission, make sure centering sleeves are correctly seated in engine.
8. Place parts that have been removed on a clean surface and cover. Use foils and paper. Use lint-free cloths only!
9. Carefully cover over opened components or seal, if repairs are not carried out immediately.
10. Only install clean components: Only unpack replacement parts immediately prior to installation.
11. Check, and if necessary correct amount of the following fluids when replacing the automatic transmission. ATF in planetary gear, gear oil in front final drive, gear oil in center differential, and capacities and specifications. See «SERVICING - A/T (01V - WITH 1.8L & 3.0L)»(/audi/a4/b6-2000-2006/remont/automatic-trans/#servicing-at-01v-with-18l-30l) article.
12. When replacing the rear final drive, check and if necessary, correct oil level in rear final drive. See «SERVICING - A/T (01V - WITH 1.8L & 3.0L)»(/audi/a4/b6-2000-2006/remont/automatic-trans/#servicing-at-01v-with-18l-30l) article.

O-RINGS, GASKETS, SEALS

1. Always replace O-rings, gaskets and sealing rings.
2. After removing gaskets and seals, always inspect the contact surfaces at housing or shaft for burrs resulting from removal or for other signs of damage.
3. Thoroughly clean housing sealing surfaces before assembling.
4. Lightly lubricate O-rings before installing, this prevents the rings from being pinched when inserting.
5. Before installing, fill gap between sealing lips of radial-shaft seals half way with sealing grease 052 128 A1.
6. The open side of the seals face toward the fluid to be sealed in.
7. For installation, lightly coat outer circumference and sealing lip with ATF or transmission oil, depending on the installation location.
8. Use only ATF in areas near ATF. Other lubricating substances cause functional problems in the hydraulic transmission control.
9. When pressing in new seals, make sure the sealing lip does not run on the same point as the sealing lip of the old seal (use insertion depth tolerances).
10. After installing, check and if necessary correct fluid levels in the affected area. ATF in planetary gear, gear oil in front final drive, gear oil in center differential, and gear oil in rear final drive. See «SERVICING - A/T (01V - WITH 1.8L & 3.0L)»(/audi/a4/b6-2000-2006/remont/automatic-trans/#servicing-at-01v-with-18l-30l) article.

NUTS, BOLTS

1. Loosen bolts in reverse order of tightening sequence.
2. Tighten and loosen bolts or nuts for securing covers and housings without tightening sequence in diagonal sequence in stages.
3. Do not cant, and loosen and tighten especially sensitive parts - e.g. valve body - in diagonal manner in stages.
4. The tightening torques stated apply to non-oiled nuts and bolts.
5. Always replace self-locking nuts and bolts.
6. Using a wire brush, clean threads of bolts which are secured with locking compound. Next, insert bolts using AMV 185 101 A1.
7. Threaded bores into which self-locking bolts or bolts with locking compound are threaded in, must be cleaned (e.g. using threaded tap). Otherwise there is danger that the bolts may shear when removed again.

CIRCLIPS

1. Do not over-stretch circlips.
2. Always replace damaged or over-stretched circlips.
3. Circlips must be fully seated in groove.

MOUNT

1. Install needle bearings with the lettering on the bearing (the side with thicker metal) facing the drift.
2. Insert bearing with transmission oil or ATF, depending on installation location.

VALVE BODY

1. Replace transmission if shift members are burnt.
2. The valve body is allocated to the transmission code letters. See «CODE LETTERS, TRANSMISSION ALLOCATIONS, RATIOS, EQUIPMENT»(/audi/a4/b6-2000-2006/remont/automatic-trans/#automatic-transmission-overhaul-01v) .

GUIDED TROUBLESHOOTING, VEHICLE ON BOARD DIAGNOSTIC (OBD) & TEST INSTRUMENTS

1. Before performing repairs on the automatic transmission, the malfunction cause must be determined as exact as possible via the VAS5051 tester in the operating modes ""Guided Fault Finding", "Vehicle Self-Diagnosis" and "Test Instruments."

1. Rules of cleanliness for working on automatic transmissions. See «Rules Of Cleanliness For Working On Automatic Transmissions»(/audi/a4/b6-2000-2006/remont/automatic-trans/#automatic-transmission-overhaul-01v__rules-of-cleanliness-for-working-on) .
