5A1 – 50IZF 4 HP 16 AUTOMATIC TRANSAXLE
DAEWOO V–121 BL4
TCC shudder should only occur during the APPLY and/or
RELEASE of the Lock up clutch.
While TCC Is Applying Or Releasing
If the shudder occurs while TCC is applying, the problem
can be within the transaxle or torque converter.
Something is not allowing the clutch to become fully en-
gaged, not allowing clutch to release, or is trying to release
and apply the clutch at the same time. This could be
caused by leaking turbine shaft seals, a restricted release
orifice, a distorted clutch or housing surface due to long
converter bolts, or defective friction material on the TCC
plate.
Shudder Occurs After TCC Has Applied :
In this case, most of the time there is nothing wrong with
the transaxle! As mentioned above, once the TCC has
been applied, it is very unlikely that will slip. Engine prob-
lems may go unnoticed under light throttle and load, but
become noticeable after TCC apply when going up a hill
or accelerating, due to the mechanical coupling between
engine and transaxle.
Important : Once TCC is applied there is no torque con-
verter assistance. Engine or driveline vibrations could be
unnoticeable before TCC engagement.
Inspect the following components to avoid misdiagnosis of
TCC shudder and possibly disassembling a transaxle and/
or replacing a torque converter unnecessarily :
S Spark plugs – Inspect for cracks, high resistance or
broken insulator.
S Plug wires – Lock in each end, if there is red dust
(ozone) or black substance (carbon) present, then
the wires are bad. Also look for a white discolor-
ation of the wire indicating arcing during hard accel-
eration.
S Distributor cap and rotor – look for broken or un–
crimped parts.
S Coil – look for black on bottom indication arcing
while engine is misfiring.
S Fuel injector – filter may be plugged.
S Vacuum leak – engine won’t get correct amount of
fuel. May run rich or lean depending on where the
leak is.S EGR valve – valve may let it too much unburnable
exhaust gas and cause engine to run lean.
S MAP sensor – like vacuum leak, engine won’t get
correct amount of fuel for proper engine operation.
S Carbon on intake valves – restricts proper flow or
air/fuel mixture into cylinders.
S Flat cam – valves don’t open enough to let proper
fuel/air mixture into cylinders.
S Oxygen sensor – may command engine too rich or
too lean for too long.
S Fuel pressure – may be too low.
S Engine mounts – vibration of mounts can be multi-
plied by TCC engagement.
S Axle joints – checks for vibration.
S TPS – TCC apply and release depends on the TPS
in many engines. If TPS is out of specification, TCC
may remain applied during initial engine starting.
S Cylinder balance – bad piston rings or poorly seal-
ing valves can cause low power in a cylinder.
S Fuel contamination – causes poor engine perfor-
mance.
TCM INITIALIZATION PROCEDURE
When one or more operations such as shown below are
performed, all learned contents which are stored in TCM
memory should be erased after the operations.
S When A/T H/W is replaced in a vehicle,
S When a used TCU is installed in other vehicle,
S When a vehicle condition is unstable (engine RPM
flare, TPS toggling and so on; at this kind of unsta-
ble conditions, mis–adaptation might be done).
1. Connect the Scan 100 with a DLC connector in a
vehicle.
2. Turn ignition switch ON.
3. Turn the power on for the Scan 100.
4. Follow the ”TCM LEARNED INITIALIZE” procedure
on the Scan 100 menu.
Notice : Before pushing ”Yes” Button for TCM initialization
on the Scan 100 screen, make sure that the condition is
as follows:
Condition :
1. Engine idle.
2. Select lever set ”P” range.

MECHANICAL COMPONENTS
Torque Converter
The converter consists of the impeller, the turbine wheel,
the reaction member (stator) and the oil to transmit torque.
The impeller, which is driven by the engine, causes the oil
in the converter to flow in a circular pattern. This oil flow
meets the turbine wheel, where is direction of flow is de-
flected. At the hub, the oil leaves the turbine and reaches
the reaction member (stator), where it is once again de-
flected so that it reaches the impeller at the correct angle
of flow.
The reversal effect generates movement in the stator, the
reaction torque then amplifies the turbine torque.
The ratio between turbine torque and torque is referred to
as torque multiplication.
The greater the difference is speed between the pump and
turbine, the greater the torque multiplication; it is at its
highest when the turbine is at a standstill. The higher the
speed of the turbine, the lower the torque multiplication.
When the turbine speed reaches about 85%of the pump
speed, torque multiplication=1, i.e. the turbine torque
equivalent to pump torque.
The stator, which bears against the housing via the free-
wheel, is then rotating freely in the oil flow and the free-
wheel is over–come. From this point onwards, the con-
verter acts as a straightforward fluid coupling.

7. Turbine hub
8. Torque converter impeller hub
Torque Converter Lock–up Clutch (TCC)
The converter lock–up clutch is a device, which eliminates
converter slip and thus helps to improve fuel consumption.
The previous control principle for converter lock–up clutch
operation has been replaced by a controlling function on
the 4 HP 16. The converter lock–up clutch is engaged and
released in a controlled manner. During the controlled
phase, a slight speed difference between the impeller and
turbine wheel is established. This ensures that the en-
gine’s rotating vibration is not phased on to the transaxle.
The result is optimum shift quality.
An electronic pressure–regulating valve determines pres-
sure regulation of the lock–up converter clutch’s piston.
When open (conversion range), the oil pressure behind
the converter lock–up clutch piston and in the turbine zone
is equal. The direction of flow is through the turbine shaft
and through the space behind the piston, to the turbine
chamber.
