4.36 DTC P2770 – Torque Converter Clutch
Enable Solenoid Control Circuit High
Voltage
DTC Description
This diagnostic procedure supports DTC P2770 Torque Converter Clutch (TCC) Enable Solenoid Control Circuit High
Voltage.
Circuit Description
The torque converter clutch (TCC) solenoid valve is an electrical device that is used with the torque converter clutch
pulse width modulation (TCC PWM) solenoid valve to control TCC apply and release. The TCC solenoid valve attaches
to the transmission case assembly extending into the pump cover. The TCC solenoid valve receives voltage through
ignition voltage circuit. The transmission control module (TCM) controls the solenoid by providing the ground path on the
TCC solenoid valve control circuit. The TCM monitors the throttle position (TP) voltage, the vehicle speed and other
inputs to determine when to energize the TCC solenoid valve.
NOTE
The TCC solenoid valve is part of the control
valve body wiring harness. To replace the
solenoid valve, the control valve body harness
must be replaced.
W hen the TCM detects a continuous short to voltage in the TCC solenoid valve control circuit, then DTC P2770 sets.
DTC P2770 is a type B DTC.
Refer to 2 W iring Diagrams and Connector Chart to aid in diagnosis.
Conditions for Running the DTC
• The system voltage is 8 – 18 V.
• The engine speed is 500 r.p.m. for 5 seconds.
Conditions for Setting the DTC
DTC P2770 sets if the TCM commands the solenoid on and the voltage feedback remains high, battery voltage.

Automatic Transmission – 4L60E – On-vehicle Servicing Page 7C4–3
1 General Information
This Section describes the removal and reinstallation procedures of the four speed 4L60E hydra-matic automatic
transmission as well as the service operations which can be performed with the transmission still fitted to the vehicle.
1.1 General Service Information
Description
The shift selector mechanism is linked to the transmission manual shaft with a selector cable. A heat protector is fitted
over the neutral start and back-up switch and manual shaft select lever.
For rear wheel drive (RWD) vehicles an extension housing is fitted to the rear of the transmission case.
Four wheel drive (4W D) vehicles have an adaptor housing and transfer case fitted to the rear of the transmission case,
for description and service operation refer to 7D Transfer Case and Adaptor Housing.
The four speed 4L60E hydra-matic automatic transmission is fitted with a filler tube, a breather hose and a vent pipe for
hot fluid overflow.
The transmission fluid is driven through a cooler within the radiator via the cooler line/hose assemblies to maintain
normal operating temperature.
Service Information

Throughout the service operations within this
Section, when handling retaining clips, using
compressed air or cleaning fluids, wear safety
equipment to avoid personal injury.
Refer to 7C1 Automatic Transmission – 4L60E – General Information for the following:
• information relating to mechanical and electrical operations,
• abbreviations, transmission specifications, special tools and torque wrench specifications,
• servicing, cleaning and inspection procedure recommendations.
It is essential to read and understand the General Information, W arnings, Cautions and Service Notes contained in that
same Section, before any service operation is performed on the four speed 4L60E hydra-matic automatic transmission or
any associated components.
Failure to comply with the procedures and service notes can affect the reliable and efficient operation of this automatic
transmission.
1.2 WARNINGS, CAUTIONS and NOTES
This Section contains various W ARNINGS, CAUTIONS and NOTE statements that you must observe carefully to reduce
the risk of death or injury during service, repair procedures or vehicle operation. Incorrect service or repair procedures
may damage the vehicle or cause operational faults. W ARNINGS, CAUTION and NOTE statements are not exhaustive.
GM HOLDEN LTD can not possibly warn of all the potentially hazardous consequences of failure to follow these
instructions.
Definition of WARNING, CAUTION and NOTE Statements
Diagnosis and repair procedures in this Section contain both general and specific W ARNING, CAUTION and NOTE
statements. GM HOLDEN LTD is dedicated to the presentation of service information that helps the technician to
diagnose and repair the systems necessary for proper operation of the vehicle. Certain procedures may present a hazard
to the technician if they are not followed in the recommended manner. W ARNING, CAUTION and NOTE statements are
designed to help prevent these hazards from occurring, but not all hazards can be foreseen.

6 Lift the locking lever (1) on the transmission fluid
indicator, then remove the indicator from the filler
tube (2) and check the fluid colour, condition and level.

Do not overfill the transmission. Overfilling
can cause aeration resulting in fluid loss,
shift complaints and possible damage to the
transmission.
7 If the transmission fluid level is low, add only enough of the recommended fluid until
its level shows onto the
crosshatch hot area (3) of the fluid indicator.
Figure 7C4 – 1
2.2 Reverse Flush and Flow Rate Test
It is essential to perform a reverse flush and oil cooler flow rate test after any of the following:
• the transmission is repaired or replaced,
• fluid contamination is suspected, or
• whenever the oil pump and/or torque converter is replaced.
NOTE
The reverse flush must be completed prior to
conducting a flow rate test.
Reverse Flush
1 Disconnect both cooler hose/line assemblies at the transmission and at the radiator cooler, refer to 3.17 Transmission Cooler Line/Hose Assemblies.
2 Check the cooler hose/line to radiator cooler fittings for damage, replace as required.

To avoid personal injury, wear safety glasses
when using compressed air.
3 Carefully check the radiator cooler lower fitting to see if any foreign material is evident at this point. If foreign material is found, remove it with a suitable tool and/or compressed air at a reduced pressure of approximately
345 kPa blown in the reverse direction through the cooler.
4 Using compressed air at a reduced pressure of approximately 345 kPa blown in a reverse direction, clean the cooler hose/line assemblies.
5 Reconnect the cooler outlet line to the transmission and both cooler hose/line assemblies to the radiator cooler fittings, refer to 3.17 Transmission Cooler Line/Hose Assemblies.
NOTE
Do not reconnect the cooler inlet line at the
transmission end. This line needs to be left
disconnected to perform the flow rate test.
6 Perform the flow rate test, refer to Flow Rate Test in this Section.
