MECHATRONIC, Removing And Installing: Installing
- Tightening specifications, refer to OVERVIEW - MECHATRONIC .
Replace the Mechatronic O-rings and bolts.
Do not bend the ATF oil pipe brackets.
-- If equipped: Remove the bolt -arrow-.
-- Remove ATF pressure pipes (clutch pressure) -1- and -2-.
The ATF pressure pipes (clutch pressure) -1- and -2- in transmissions for the new version are a single unit and made out of plastic. In this case, the ATF pressure pipe (clutch pressure) must be replaced. There is no bolt -arrow- and no bracket for the ATF pressure pipe.
-- For metal ATF pressure pipes (coupling pressure): Replace the O-rings on the ATF pressure pipes -1- and -2-.
-- For plastic ATF pressure pipes (coupling pressure): Replace the ATF pressure pipes -1- and -2-.
-- Remove the ATF pipes -3 through 5-.
The ATF pipes -3 through 5- in transmissions for the new version are a single unit and made out of plastic. In this case, the ATF pipes must be replaced.
-- Metal ATF pipe: replace the O-rings on the ATF pipes -3 through 5-.
-- Plastic ATF pipes: replace ATF pipes -3 through 5-.
-- Coat all of the O-rings with ATF.
-- Insert all of the ATF pipes -1 through 5- again.
-- If equipped: Tighten the bracket and the bolt -arrow-.
Make sure all shift forks and gear positions are in the center position before installing the DSG Transmission Mechatronic -J743-.
Adjust the Shift Forks:
-- First check the shift positions for the shift forks -1 through 4- by hand.
Each shift fork has three positions:
- -G- is engaged
- Idle -N- (center position)
- -G- is engaged
-- Move all four shift forks one time into each position -arrows- one after the other.
-- After doing this, move the shift forks back into the center position -N-.
Adjust the Gear Selector:
There is a risk of destroying the transmission control module (Mechatronic) with static discharge.
- Always "discharge" the static electricity before working with electric connectors. Do this by touching a grounded object, for example vehicle ground, the vehicle or the hoist.
- Do not touch contacts in transmission connector with hands.
- Do not pry out the plunger on the sensors.
The gear shifter must be adjusted differently depending on the date of manufacture of the Mechatronic.
The date of manufacture is located only on the Mechatronic identification -arrow-.
The Mechatronic identification consists of:
| Mechatronic identification | Example "L31B1138" | |||
|---|---|---|---|---|
| L | 31 | B1 | 138 | |
| L | Year of manufacture: L = 2010 K = 2009 J = 2008... etc. | |||
| 31 | Calendar week in the year of manufacture | |||
| B1 | Manufacturer day shift identification: Monday: Shift 1 = A1, Shift 2 = B1, Shift 3 = C1 Tuesday: Shift 1 = D1, Shift 2 = E1, Shift 3 = F1 Wednesday: Shift 1 = G1, Shift 2 = H1, Shift 3 = I1... etc. | |||
| 138 | Running manufacturing number of the shift per day, here, the 138 Mechatronic from shift B1 | |||
The gear positions must be adjusted to a different adjustment value from Mechatronic "L31B1138".
A Mechatronic with the identification. "L31A1140" was built before Mechatronic "L31B1138" because it was built by the 1st shift (A1) on a Monday.
A Mechatronic with the identification "L31C1009" was built after Mechatronic "L31B1138" because it was built by the 3rd shift (C1) on Monday.
-- Move the gear position back and forth and set the 4 gear positions on the back of the Mechatronic in the center position to dimension -a-.
For Mechatronic with Identification Through "L31B1137" :
- Dimension -a- = 28 mm
For Mechatronic with Identification From "L31B1137" :
- Dimension -a- = 32 mm.
-- Align the gear selector yokes -arrows- so that they engage into the eyes in the shift fork when being installed.
-- Insert the Mechatronic into the transmission housing.
- The Mechatronic and its bolts must fit easily into the holes in the transmission.
- If the Mechatronic does not go in easily, then it is possible that a shift fork or a gear selector is not in its center position. Check the center position and adjust if necessary.
After installing the Mechatronic:
-- Using a flashlight, check all the gear selectors through the opening between the Mechatronic and the transmission housing.
- All four gear selector yokes must fit correctly in the shift fork eyes.
-- Tighten the Mechatronic bolts, refer to Figure.
Install in reverse order, paying attention to the following:
There is a risk of destroying the transmission control module (Mechatronic) with static discharge.
- Always "discharge" the static electricity before working with electric connectors. Do this by touching a grounded object, for example vehicle ground, the vehicle or the hoist.
- Do not touch contacts in transmission connector with hands.
-- Make sure the connector is correctly connected to the Mechatronic.
-- Install the ATF suction filter, refer to ATF FILTER, REMOVING AND INSTALLING .
-- Install the ATF pan, refer to OIL PAN, REMOVING AND INSTALLING .
-- Install the ATF filter housing or ATF line connecting pieces (depending on the version):
- Audi A6, A7, refer to AUTOMATIC TRANSMISSION FLUID (ATF) STRAINER, REMOVING AND INSTALLING or MECHATRONIC .
Danger of leaks!
- Always replace the seals on the oil lines and the filter housing and coat with ATF.
- Ensure a clean sealing surface.
Transmission Removed.
-- Install the transmission:
- Audi A6, A7, refer to TRANSMISSION, REMOVING AND INSTALLING .
The Transmission is Installed.
-- Filling the ATF:
- Audi A6, A7, refer to AUTOMATIC TRANSMISSION FLUID (ATF), DRAINING AND FILLING .
- Perform "Guided Functions" using the Vehicle Diagnostic Tester after replacing the DSG Transmission Mechatronic -J743-.
- Audi A6, A7, refer to MECHATRONIC .
