Technical Service 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 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 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.

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.

DESCRIPTION OF SOLENOID OPERATION
EV-1 (N88) This solenoid feeds the K-1 clutch when it is de-energized (Off), and feeds the B-1
brake when it is energized (On), in Park, Neutral and 4th.
This solenoid is energized in 2nd and 4th to apply the B-2 brake.
This solenoid controls the K-3 clutch
This PWM solenoid applies the converter clutch when it is energized (On) and is
dependent on engine temp, vehicle speed and throttle position.
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.
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.

All castings and spacer plates have been numbered so they can be
identified in an oil circuit diagram. Example: 329U passage is
located in the Upper valve body (300U series). This passage can
now be located in the partial oil circuit diagram shown above.
Spacer plate orifice sizes and locations are also identified in the oil
circuit diagram labled Valve body Mapping.

VOLKSWAGEN / AUDI
UNCONTROLLABLE HARSH 1-2 UPSHIFT
Before or after overhaul, vehicles equipped with 01M, 01N and 01P transaxles, may exhibit a
harsh 1-2 upshift along with firmer than normal engagements as well as firm upshifts to 3rd
and 4th.
CAUSE: The cause may be,
1. Erratic or high line pressure.
2. An electrical malfunction in the EV5 solenoid electrical circuit.
3. A Hydraulic malfunction with EV5 solenoid.
(NOTE: The EV5 solenoid is grounded on each engagement and each upshift and
downshift which helps control Clutch apply Pressure for smooth engagements as shown
in Figures 3 and 4.)
CORRECTION: To correct this condition:
1. Connect a pressure gage to the line pressure port as shown in Figure 1. Line pressure
should indicate 60 psi. in the Drive position at idle and should increase to 120-150 psi. at
stall. Line pressure should cut back to between 65-75 psi. on each shift. If Line pressure
does not cut back on each shift, or is at 120-150 psi. at all times, or is erratic on the gage,
replace the EV6 solenoid and check the Boost Regulator and Main Regulator valve to
ensure they are not stuck. Refer to Figure 2 for a description of how EV6 Solenoid
operates.
2. Refer to Figure 5 and locate terminal 7 at harness connector. Back probe that terminal to
verify that the computer is grounding EV5 during the 1-2 upshift. If the computer is not
grounding that terminal, go to STEP A. If the Computer is grounding that terminal go to
STEP B.
STEP A. Connect a scan tool to the diagnostic connector and check to see if the TCM has
set a trouble code 00266 (VAG) or a P0773 which are EV5 solenoid circuit faults. Repair
the EV5 Solenoid circuit as needed. If the TCM has no trouble codes set and does not
ground EV5 Solenoid during the 1-2 shift, the TCM may be faulty.
STEP B. Go to Correction number 3.
3. Remove EV5 Solenoid from its bore. Ensure that the B1 Apply valve, which is located
below the solenoid, is not sticking in it’s bore. Air check EV5 solenoid and ensure it’s
proper operation as shown in Figure 6. If EV5 Solenoid does not close consistently replace
as needed.

1996-2000 OBD-II CODE DEFINITIONS
When a VW/Audi vehicle is exhibiting a symptom or is in fail-safe, the technician, in many
cases, is unable to communicate with the on-board diagnostics in order to retrieve codes.
The lack of aftermarket equipment, previously available to the technician, to allow access
to vehicle on-board diagnostics such as, code retrieval, data lists and basic setting resets.
With the OBD-II mandate beginning in 1996, it is possible to retrieve codes using the
Generic OBD-II part of your scan tool. This will also allow access to the "freeze frame" and
"pending code" categories which are diagnostic aids to help the technician retrieve codes
and data.
There have also been recent developments which have made available, diagnostic tools
which can communicate with VW/Audi vehicle modules which include pre-OBD-II
diagnostics for codes and data.
Use the illustrations in figures 1 and 2 for diagnostic connector locations in all
Volkswagen/Audi models equipped with 096, 097, 098, 01M, 01N and 01P transmissions.
Use the code definition charts in figures 3 to 12 for ECM codes for gasoline engine equipped
vehicles.
Use the code definition charts in figures 13 to 15 for ECM codes for diesel engine equipped
vehicles.
Use the code definition charts in figures 16 and 17 for TCM codes.

VOLKSWAGEN/AUDI
MANUAL PROCEDURE FOR "RETURN TO BASIC SETTINGS"
Once a Volkswagen/Audi vehicle has been repaired, in many cases, the Transmission
Module (TCM) or the Engine Control Module (ECM) does not allow proper vehicle
operation.
The symptoms may be, the transmission stuck in "Failsafe" or erratic shifting accompanied
by driveability complaints.
It is of primary importance to clear all previously stored trouble codes, this is NOT an option.
It is recommended to use a scan tool or computer based program to do this. Both are
available to the aftermarket. 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.
If no other method is available, disconnecting the battery for one minute will clear the codes.
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.
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.
The "Return To Basic Settings" MUST be performed if any of the following conditions
exist: 1. Replacement of the ECM.
2.The engine has been changed.
3. Repair or replacement of the throttle housing.
4. Replacement or adjustment of the Throttle Position Sensor.
5. Replacement of the TCM.
Use the following procedure on all VW/AUDI vehicles equipped with 096, 097,098, 01M,
01N or 01P transmissions, to manually reset the "Basic Settings":
1. Turn the ignition "ON", Do not start the engine.
2. Move the gear selector lever to the "D4" position.
3. Depress the accelerator pedal all the way to the floor and hold it there for 30 seconds.
Make certain the carpet or floor mat is not in the way of the pedal.
4. After 30 seconds, move the gear selector lever back to "PARK".
5. Release the accelerator pedal.
6. Turn the ignition "OFF".
7. After completion of the above, drive the vehicle on the road and perform three
individual upshift sequences and kickdown at light, medium and heavy throttle
conditions.
NOTE: The systems will fine tune themselves over the next 50 to 75 miles of driving.
