Type 096 Transmission
Golf and Jetta Transmission Installation
The "096" 4-speed automatic transmission is installed in the Golf III and Jetta III beginning in the 1993 model year, and in the Cabrio beginning in the 1995 model year.
The maximum possible care and cleanliness and proper tools are essential to ensure satisfactory and successful transmission installation. A number of generally applicable instructions for individual transmission installation, which are otherwise mentioned at various Repair Manuals, are summarized here.
When installing the torque converter, make sure that both drive pins engage in the ATF pump inner wheel recesses. Before installing, make sure that dowel sleeves for aligning the engine and transmission are correctly located. Make sure that during installation the Multi-Function Transmission Range (TR) Switch -F125- does not contact the subframe and break. When you need exact instruction on how to install the transmission refer to a Repair manual. When you do NOT install the transmission properly, even a new transmission will NOT run right. Don't torque the trani down with your power tools, the font pump might break. We may NOT warranty a broken front pump after the installation. When your front seal is leaking, you have NOT been careful enough, you broke the seal during the installation. We guarantee you that the transmission runs before it leaves the shop, we install all new parts and we bench test the transmission, we can NOT warranty the trani runs properly, after you install it, because there are too many factors that are out of our control (like speed sensor or throttle position sensor as example), we do Not know if everything functions how it is supposed to be. The only way to be sure that the trani runs perfectly is to perform all tasks like the manufacturer requires.
When an automatic transmission is replaced, the ATF in the planetary transmission and the gear oil in the final drive is to be checked and topped up as necessary. So.. after installing, check gear oil level or ATF level and adjust to correct level if necessary

Oil in final drive, checking |

Oil level is checked with transmission installed. | |||||||||
The difference
between the "Min" and "Max" marks is approx. 0.1 liter (3.4 fl. oz.). Excess
oil can be drawn off using the VAG 1358A extraction system or EZ1 fluid
evacuator. Checking:
|
Vehicle parked on level surface, parking brake applied. Selector lever at "P" and engine running at idle speed. When cold, the ATF should be visible up to the 20C marking
|
Too much ATF will cause transmission malfunctions and must therefore be extracted |
Only ATF with the designation Dexron may be used. Do not use any lubricant additives |
Bring ATF up to normal operating temperature - approx. 60C (140F)
It is essential that the ATF level is between the Min. and Max. markings
After you install the transmission and before you crank the Engine perform following tests
Test conditions:
Battery Positive Voltage (B+) OK ? Fuses 14 (S14) and 21 (S21) OK ?
Check transmission Ground (GND) connections. Check Ground connections for corrosion and poor contact; repair if necessary. Ground (GND) connection on left next to relay panel.
Check Battery Ground (GND) strap and Ground (GND) strap between Battery and transmission.
Transmission Control Module (TCM) recognition of malfunctions
Your old transmission stored a number of Diagnostic Trouble Codes "DTC Memory" in your computer ( ECU). Before you test drive the car, you have to erase all the codes in your ECU. Other wise you have drivability problems and you are in danger to break your transmission again.
Depending on which model of car you have, you have two places to connect your scan tool to reset the codes.
Erase DTC memory the Diagnostic Trouble Codes Memory, erasing
Only If "No DTC recognized" appears on your scanning Tool , the On Board Diagnostic program has been completed
When the DTC Memory is interrogated, the following message should be displayed:
"No DTC recognized" |
Note:
If the ignition was switched OFF, between checking and erasing the DTC Memory for example, then the DTC Memory will not be erased.
- Adhere strictly to the sequence of operations, i.e. always check DTC Memory first before attempting to erase.
After checking and erasing DTC Memory, carry out a test drive and checking DTC Memory again. In the event that the automatic transmission does not operate properly despite carrying out the On Board Diagnostic program, this let you know the cause of the malfunction.
Electrical malfunctions that affect vehicle performance can be identified using the VAG 1551 Scan Tool (ST). The On Board Diagnostic (OBD) capabilities can only be fully exploited using operating mode 1 ("Rapid data transfer").
An automatic check can be carried out in the "Rapid data transfer" operating mode. Then all vehicle control units will be interrogated automatically
After you replaced the transmission, the Transmission Control Module (TCM) -J217- should be brought into the basic settings because the malfunction has been determined and the malfunctions have been corrected. If the Transmission Control Module (TCM) -J217- is replaced the system must also be brought into basic settings.
