The "01M" transaxle is a 4 speed unit, with 4th gear being overdrive, and is equipped with a clutch in the torque converter. Refer to the chart in Figure 1 for the internal components that are applied in each of the four forward gear ranges. Notice that it has only one freewheel device for 1st gear. Vehicle Cabrio Beetle Golf GTI Jetta Passat "01M" MODEL USAGE CHART Years Engine Size 1995-2001 2.0L (L4) 1998-2001 1.8L (L4), 2.0L (L4), 1.9L Diesel 1995-2001 1.8L (L4), 2.0L (L4), 1.9L Diesel 1999-2001 1.8L (L4), 2.8L (V6) 1995-2001 1.8L (L4), 2.0L (L4), 1.9L Diesel, 2.8L (V6) 1995-1997 2.0L (L4), 2.8L (V6) The "01M" transaxle is totally electronic controlled and uses a Electronic Control Unit (ECU) to control shift points, apply and release of the torque converter clutch, and line pressure control. This is done using seven solenoids located on the valve body. The solenoid pattern for each gear and the description of operation is provided for you in Figure 2. Electrical signals from various sensors provide information to the ECU about vehicle speed, throttle position, engine coolant temperature, transaxle fluid temperature, gear range selected, converter turbine speed, engine load and engine speed. The ECU uses this information to determine the precise moment to upshift or downshift, apply or release the TCC and what fluid pressures are needed to apply the components. If for any reason the entire electronic control system of the transaxle becomes disabled, or the ECU detects a problem with one of the various sensors that stores a trouble code, all of the solenoids will be de-energized (Turned OFF). This "Safety Mode" operating state of the solenoids forces the transaxle to operate in 3rd gear when the selector lever is in the "Drive" range. We have provided you with an internal wire schematic and case connector pin identification in Figure 3, and a chart in Figure 4 to check the resistance of the solenoids and fluid temperature sensor. Refer to Figure 5 to check solenoid mechanical operation on the bench. Figures 6, 7 and 8 will provide you with exploded views of the valve body and all valve body components along with the names of each valve. The names of the valves are ATSG interpretations of the valves functions, not Volkswagens. Figure 9 will provide you with the valve body spring specifications that we observed in the valve body that was used for the illustrations, and may be different in the various models. Refer to Figures 10 and 11 for the checkball locations in this unit and Figure 12 for air checks.

EV-2 (N89) This solenoid is energized in 2nd and 4th to apply the B-2 brake. EV-3 (N90) This solenoid controls the K-3 clutch *EV-4 (N91) This PWM solenoid applies the converter clutch when it is energized (On) and is dependent on engine temp, vehicle speed and throttle position. **EV-5 (N92) This solenoid is energized (On) during every shift, to drop line pressure, and orifices the apply oil to each clutch pack during the shift to provide smoother shifts. After the shift is completed, the solenoid is de-energized (Off). ***EV-6 (N93) This PWM solenoid controls main line pressure anytime the engine is running. This is a Pulse Width Modulated signal that varies with engine load and throttle position. When the solenoid is de-energized (Off) pressure goes to maximum. EV-7 (N94) This solenoid controls the apply oil to the B-2 brake, to provide smoother shifts into 4th gear. It will also be energized (On) momentarily during the 2-3 shift.

The symptoms may be. After 30 seconds. move the gear selector lever back to "PARK". to manually reset the "Basic Settings": 1. Replacement or adjustment of the Throttle Position Sensor.098. It is of primary importance to clear all previously stored trouble codes. Replacement of the TCM. Depress the accelerator pedal all the way to the floor and hold it there for 30 seconds. the transmission stuck in "Failsafe" or erratic shifting accompanied by driveability complaints. Turn the ignition "OFF". 5. 3. Repair or replacement of the throttle housing. 7. CAUSE: Copyright © 2001 ATSG AUTOMATIC TRANSMISSION SERVICE GROUP . The "Return To Basic Settings" MUST be performed if any of the following conditions exist: 1. 4. It is recommended to use a scan tool or computer based program to do this. Do not start the engine. NOTE: Some codes can be cleared on OBD-II equipped vehicles using the Generic area of the scan tool if specialty equipment is not available. Both are available to the aftermarket. 01M. NOTE: The systems will fine tune themselves over the next 50 to 75 miles of driving.INDEX Technical Service Information VOLKSWAGEN/AUDI MANUAL PROCEDURE FOR "RETURN TO BASIC SETTINGS" COMPLAINT: Once a Volkswagen/Audi vehicle has been repaired. Replacement of the ECM. 5. 6. 097. CORRECTION: Use the following procedure on all VW/AUDI vehicles equipped with 096. Release the accelerator pedal. 2. the Transmission Module (TCM) or the Engine Control Module (ECM) does not allow proper vehicle operation. this is NOT an option. After completion of the above. Disconnecting the battery to accomplish this is not recommended due to other systems that may be adversely effected such as radio theft codes or the vehicle 's theft deterrent system. 2. Move the gear selector lever to the "D4" position. 4. If no other method is available. 3. medium and heavy throttle conditions.The engine has been changed. disconnecting the battery for one minute will clear the codes. The next mandatory procedure that MUST be performed is the "Return To Basic Settings" which is the Throttle Position Sensor and Kickdown relearn settings that both the TCM and the ECM must have in order to send proper commands for engine and transmission operation. Make certain the carpet or floor mat is not in the way of the pedal. Turn the ignition "ON". 01N or 01P transmissions. drive the vehicle on the road and perform three individual upshift sequences and kickdown at light.
