General Repair Notes
To ensure flawless and successful transmission repairs, the greatest care and cleanliness as well as the use of good and proper tools is essential. The usual basic safety precautions also, naturally apply when carrying out vehicle repairs.
A number of generally applicable instructions for individual repair operations, which are otherwise mentioned at various points in the article, are summarized here. They apply to this article.
Transmission
After installing, following fluid levels must be checked and topped off if necessary:
O-rings, gaskets, seals
- O-rings, gaskets and seals must be replaced.
- After removing gaskets, examine contact surface on housing/shaft for burr resulting from removal or for other signs of damage.
- Open sides of oil seals face fluid side.
- To install, thinly coat gaskets along outer circumference and on sealing lip with ATF.
- Coat O-rings with transmission fluid or Vaseline before inserting to prevent crushing rings during installation.
- Use only ATF or Vaseline in areas near ATF. Other types of lubrication cause malfunctions to occur in the transmission hydraulics.
- When pressing in new gaskets, make sure the sealing lip does not run on the same point as the sealing lip of the old seal (use insertion depth tolerances).
- Replace paper seals, always clean sealing surfaces and remove old seals completely.
Bolts and nuts
- Loosen bolts in reverse order of tightening.
- Loosen and tighten bolts and nuts for securing covers and housings in a diagonal sequence and in stages, when no tightening sequence is specified.
- The tightening torques stated apply to unoiled bolts and nuts.
- Replace self-locking bolts and nuts.

Locking elements
- Do not over-stretch circlips.
- Always replace circlips which have been damaged or over-tensioned.
- Circlips must be properly seated in the base of the groove.
- Replace spring pins. Installation position: Slot is longitudinal to line of force.
Bearings
- Slightly grease mount with ATF before inserting.
- Attach mount and adjustment shims only with Vaseline. Other lubricants cause malfunctions of the hydraulic transmission controls.
Contact corrosion!
General:
Contact corrosion can occur if non-approved fasteners are used on vehicle (bolts, nuts, washers, etc.).
For this reason, all fasteners used in production are specially treated. These parts can be identified by their greenish color.
Rubber, plastic and adhesives also consist of non-conductive materials.
If you are not sure whether used parts can be re-installed, always install new parts.
The following points should be observed especially for transmission:
- Multitronic transmission 01J or 0AN housing is made of magnesium alloy.
- Bolts and other components which have direct contact with transmission have a surface coating which is matched to magnesium transmission housing.
- On magnesium transmissions, bolts must always be replaced on following bolted connections: Transmission housing cover and final drive cover on transmission housing as well as engine bolts on transmission.
- Contact corrosion occurs when incorrect components (bolts, nuts, washers, etc.) are used. The transmission housing will be damaged.
- Transmission housing, transmission cover and differential cover must all be of same material.
- If you are not sure whether used parts can be re-installed, always install new parts.
CAUTION: |
- Accessories must be approved by AUDI AG!
- Damage resulting from contact corrosion is not covered by the warranty!
|
Rules for cleanliness when working on transmission
- Carefully clean all joints and adjacent areas before disconnecting.
- Place removed parts on a clean surface and cover them. Use sheeting or paper. Use lint-free cloths only!
- Carefully cover or plug unpacked components if repairs cannot be performed immediately.
- Only install clean parts: Remove packing from replacement parts immediately prior to installation and not before.

Work procedure
With normal ATF change, only about 55 to 60% of total ATF in transmission is replaced.
"ATF flush" procedure is necessary when old ATF in transmission must be removed completely.
ATF must always be flushed with following procedures:
- Changing input shaft
- Servicing input shaft
In addition, test run must be performed 2 times and afterwards ATF must be changed, as described below.
Only by doing this will ATF in transmission be changed completely.
CAUTION: |
If all these steps are not followed completely, transmission components will be damaged. |
CAUTION: |
- After installing the transmission with a new disc pack or input shaft, the Vehicle Diagnosis, Testing and Information System VAS 5051 A must check before the first drive whether or not update programming in the Transmission Control Module (TCM) J217 must be carried out.
- If update programming is needed but not carried out, transmission components will be damaged.
- If update programming is not needed but carried out, transmission components will be damaged.
|
Check whether update programming in the Transmission Control Module (TCM) J217 must be carried out.
- Vehicle Diagnosis, Testing, and Information System VAS 5051 connected.
- Vehicle-specific access to Vehicle Diagnosis, Testing, and Information System VAS 5051 in "Guided Fault Finding".
- Using Goto button, select "Complaint registration " function in test plan and find following selection:
Text lines to select |
"Repair solution" |
|

|
|
|
" Jerking when accelerating from stop" |
- Press " Transfer" text line and select test program " Jerking when accelerating from stop".
NOTE: |
- Through this process in Vehicle Diagnosis, Testing, and Information System VAS 5051 update programming is only carried out for the Transmission Control Module (TCM) J217 if this is necessary.
|
- If necessary, carrying out update programming in Transmission Control Module (TCM) J217.
ATF flush
CAUTION: |
If all steps are not carried out in correct order or followed exactly, transmission components will be damaged. |
NOTE: |
- Observe all notes and test requirements for "Checking ATF level and topping off".
|
After ATF level is checked and restored, flushing process is complete.
Input shaft adjustment (air gap), checking
CAUTION: |
Do not allow engine to run without filling ATF and do not tow the vehicle. |
- Place vehicle on level surface.
NOTE: |

If vehicle rolls in selector lever position "N":
If selector lever cable adjustment is OK but vehicle still rolls in selector lever position "N":
NOTE: |
- In this case, input shaft adjustment (air gap) was not performed correctly.
|
If vehicle does not roll in selector lever position "N" :
The input shaft adjustment with evaluation of air play is OK.
- Carry out ATF flush First test run pass through:
