Clean and Inspect

Do not use solvents on neoprene seals,
composition faced clutch plates or thrust
washers as damage to parts may occur.
After complete disassembly of a component, wash all metal parts in a clean solvent and dry with compressed air. Blow
oil passages out and check to make sure they are not obstructed, small passages should be checked with tag wire. All
parts should be inspected to determine if replacement is required.
Pay particular attention to the following:
• Inspect linkage and pivot points for excessive wear.
• Bearing and thrust surfaces of all parts should be checked for excessive wear and scoring.
• Check for broken seal rings, damaged ring lands and damaged threads.
• Inspect seals for damage.
• Mating surfaces of castings should be checked for burrs. Irregularities may be removed by lapping the surface with
emery paper laid on a flat surface, such as a piece of plate glass.
• Castings should be checked for cracks and porosity.

For transmissions fitted to V6 engines, the electrical diagnosis is in this Section. A new electrical circuit and control
module has been introduced for automatic transmissions fitted to the V6 engines.
1.4 7C3 Automatic Transmission – 4L60E – Hydraulic and Mechanical Diagnosis
Information contained in 7C3 Automatic Transmission – 4L60E – Hydraulic and Mechanical Diagnosis will assist in the
diagnosis of the mechanical and hydraulic components in the 4L60E automatic transmission, while the transmission
remains installed on the vehicle.
Examples of the type of diagnostic information contained within this section are:
• transmission functional test,
• line pressure information,
• transmission fluid diagnosis,
• symptom diagnosis and
• shift speed charts.
1.5 7C4 Automatic Transmission – 4L60E –
On-vehicle Servicing
Information in 7C4 Automatic Transmission – 4L60E – On-vehicle Servicing covers transmission fluid level checking, as
well as specific information for servicing some components while the transmission remains installed on the vehicle. This
Section also covers the transmission removal and reinstallation to the vehicle.

Automatic Transmission – 4L60E – General Information Page 7C1–12
General Definition
Check Ball A spherical, hydraulically controlled component (usually of steel) that either seals or
opens fluid circuits. It is also referred to as a check valve.
Clutch Pack An assembly of components generally consisting of clutch plates, an apply plate and a
backing plate.
Clutch Plate A hydraulically activated component that has two basic designs: (1) all steel, or (2) a
steel core with friction material bonded to one or two sides of the plate.
Control Valve Body A machined metal casting that contains valve trains and other hydraulically controlled components that shift the transmission.
Coupling Speed The speed at which a vehicle is travelling and no longer requires torque multiplication through the torque converter. At this point, the stator 'free wheels' to allow fluid leaving
the turbine to flow directly to the pump. (Also see Torque Converter).
De-energise(d) To interrupt the electrical current that flows to an electronically controlled device,
making it electrically inoperable.
Direct Drive A condition in a gears set where the input speed and input torque equals the output
speed and output torque. The gear ratio through the gear set is 1:1.
Downshift A change in a gear ratio where both input speed and torque increases.
Duty Cycle In reference to an electronically controlled solenoid, it is the amount of time (expressed
as a percentage) that current flows through the solenoid coil.
Energise(d) To supply a current to an electronically controlled device, enabling it to perform its
designed function.
Engine Compression Braking A condition where compression from the engine is used with the transmission to decrease vehicle speed.
Exhaust The release of fluid pressure from a hydraulic circuit. (The words 'exhausts' and
'exhausting' are also used and have the same intended meaning.)
Fail-safe Mode A condition whereby a component (i.e. engine or transmission) will partially function even if its electrical circuit is disabled.
Fluid In this Section of the Service Manual, 'fluid' refers primarily to automatic transmission
fluid (or ATF) and, for the Hydra-matic 4L60E transmission, the only recommended
fluid is Dexron
III.
Fluid Pressure A pressure that is consistent throughout a given fluid circuit.
Force A measurable effort that is exerted on an object (component).
Freewheeling A condition where power is lost through a driving or holding device (i.e. roller or sprag
clutches).
Friction Material A heat and wear resistant fibrous material, bonded to clutch plates and bands.
Gear A round, toothed device that is used for transmitting torque through other components.
Gear Range A specific speed to torque ratio at which the transmission is operating (i.e. 1st gear,
2nd gear etc.).
Gear Ratio Revolutions of an input gear as compared to the revolutions of an output gear. It can
also be expressed as the number of teeth on a gear as compared to the number of
teeth on a gear that it is in mesh with.
Hydraulic Circuit A fluid passage which often includes the mechanical components in that circuit
designed to perform a specific function.
Input A starting point for torque, revolutions or energy into another component of the
transmission.
Internal Gear The outermost member of a gear set that has gear teeth in constant mesh with the
planetary pinion gears of the gear set.
Land (Valve Land) The larger diameters of a spool valve that contact the valve bore or bushing.

4.18 DTC P0741 – Torque Converter Clutch
System – Stuck Off
DTC Description
This diagnostic procedure supports DTC P0741 Torque Converter Clutch (TCC) System - Stuck Off.
Circuit Description
The torque converter clutch (TCC) solenoid valve is a normally-open exhaust valve that is used with the torque converter
clutch pulse width modulation (TCC PWM) solenoid valve to control fluid acting on the converter clutch apply valve. The
TCC solenoid valve attaches to the transmission case assembly extending into the pump cover. W hen grounded by the
transmission control module (TCM), the TCC solenoid valve stops converter signal oil from exhausting. This causes
converter signal oil pressure to increase and move the converter clutch apply valve against spring force and into the
apply position. In this position, release fluid is open to an exhaust port and converter feed fluid fills the apply fluid circu it.
The converter feed fluid applies the TCC. When the TCM no longer provides a ground path, the TCC solenoid valve de-
energizes and apply fluid exhausts, releasing the TCC.
When the TCM detects high torque converter slip when the TCC is commanded off, then DTC P0741 sets. DTC P0741 is
a type B DTC.
Refer to 2 W iring Diagrams and Connector Chart to aid in diagnosis.
