Technical Service Information VOLKSWAGEN "01M" PRELIMINARY INFORMATION The "01M" designated transaxle, shown in Figure 1, first appeared in the 1995 model year and was used in a wide variety of the Volkswagen Volkswagen car lines along with various engine combinations, including the 2.8L V6 engine, as shown in the chart below. The "01M" transaxle is a 4 speed unit, with with 4th gear being overdrive, and is equipped with a clutch in the torque torque converter. Refer to the chart in Figure 1 for the internal components that are applied in in each of the four forward gear ranges. Notice that it has only one freewheel device for 1st gear.

The "01M" transaxle is totally electronic controlled and uses a Electronic Control Control Unit (ECU) to control 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 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 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 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 in 3rd gear when the selector lever is in the the "Drive" range. We have provided you with an internal wire schematic 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 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, illustrations, and may be different different in the various models. Refer to Figures 10 and 11 for the checkball locations in this unit and Figure 12 for air checks.
