This bulletin is being revised to add model years. Please discard Corporate Bulletin Number 03-07-29-004G (Section 07 - Transmission/Transaxle).



Important:



Even though this bulletin attempts to cover operating characteristics of manual transmissions, it cannot be all inclusive. Be sure to compare any



questionable concerns to a similar vehicle and if possible, with similar mileage. Even though many of the conditions are described as characteristics



and may not be durability issues, GM may attempt to improve specific issues for customer satisfaction.



2010 Cadillac Truck SRX AWD V6-2.8L Turbo Page 40



The purpose of this bulletin is to assist in identifying characteristics of manual transmissions that repair attempts will not change. The following are



explanations and examples of conditions that will generally occur in all manual transmissions. All noises will vary between transmissions due to



build variation, type of transmission (usually the more heavy duty, the more noise), type of flywheel and clutch, level of insulation, etc.



Basic Information



Many transmission noises are created by the firing pulses of the engine. Each firing pulse creates a sudden change in angular acceleration at the



crankshaft. These changes in speed can be reduced with clutch damper springs and dual mass flywheels. However, some speed variation will make



it through to the transmission. This can create noise as the various gears will accel and decel against each other because of required clearances.



Cold Operation



Manual transmission operation will be affected by temperature because the transmission fluid will be thicker when cold. The thicker fluid will



increase the amount of force needed to shift the transmission when cold. The likelihood of gear clash will also increase due to the greater time



needed for the synchronizer assembly to perform its function. Therefore when the transmission is cold, or before it has reached operating



temperature, quick, hard shifts should be avoided to prevent damage to the transmission.



Gear Rattle



Rattling (not to be confused with a missed shift type of grinding, also described as a combustion knock type of noise) type noises usually occur



while operating the engine at low RPMs (lugging the engine). This can occur while accelerating from a stop (for example, a Corvette) or while



operating at low RPMs while under a load (for example, Kodiak in a lower gear and at low engine speed). Vehicles equipped with a dual-mass



flywheel (for example, a 3500 HD Sierra with the 6-speed manual and Duramax) will have reduced noise levels as compared to vehicles without



(for example, a 4500 Kodiak with the 6-speed manual and Duramax). However, dual-mass flywheels do not eliminate all noise.



Neutral Rattle



There are often concerns of rattle while idling in neutral with the clutch engaged. This is related to the changes in angular acceleration described



earlier. This is a light rattle, and once again, vehicles with dual mass flywheels will have reduced noise. If the engine is shut off while idling in



neutral with the clutch engaged, the sudden stop of the engine will create a rapid change in angular acceleration that even dual mass flywheels



cannot compensate. Because of the mass of all the components, this will create a noise. This type of noise should not be heard if the clutch is



released (pedal pushed to the floor).



Backlash



Backlash noise is created when changing engine or driveline loading. This can occur when accelerating from a stop, coming to a stop, or applying



and releasing the throttle (loading and unloading the driveline). This will vary based on vehicle type, build variations, driver input, vehicle loading,



etc. and is created from the necessary clearance between all of the mating gears in the transmission, axle(s) and transfer case (if equipped).



Shift Effort



Shift effort will vary among different style transmissions and synchronizer designs. Usually the more heavy duty the transmission, the higher the



shift effort because of the increased mass of the components. Shift effort can also be higher in cold weather because the fluid will be thicker.



Medium duty transmissions will not shift as quickly as a Corvette transmission. To reduce shift effort, do not attempt to rush the shift - allow the



synchronizers to work as designed. Shifting harder will only increase the chance of rushing past the synchronizer leading to grinding while shifting.



Non-Synchronized Gears



Some light duty truck transmissions in 1st gear (creeper-gear) and reverse gears in various transmissions, along with all gears in some medium duty



transmissions, may be non-synchronized. This means there is not a mechanism to match input and output shaft speeds to allow for a smooth shift.



This function is left up to the driver. This can be noticed if a shift into 1st or reverse is attempted while the vehicle is rolling or before the input



shaft stops rotating leading to a gear grind. The grinding can be reduced by coming to a complete stop and pausing for a moment before shifting



into the 1st or reverse gear. Some slight grinding can be expected. In medium duty non-synchronized transmissions, the driver must match input



shaft (engine) speed to output shaft (driveshaft) speed with every shift. This can be accomplished by double clutching, or by using other methods. If



the driver is not able to perform this function properly, there will be gear grinding with each improperly completed shift. Driver training may be



required to correct this condition. Clutch brakes are used in medium duty non-synchronized transmissions to allow a shift into gear at a stop. The



clutch brake is used to stop the input shaft from spinning, allowing a shift into gear at a stop without grinding. The clutch brake is activated by



pressing the clutch pedal all the way to the floor. When the clutch brake is used, it is possible to have a blocked shift with the vehicle stationary. If



this occurs, engage the clutch slightly to rotate the input gear to allow the shift. The clutch brake is intended to only be used while at a stop. Care



must be taken to not activate the clutch brake while shifting between gears. This could lead to excessive grinding or a blocked or missed shift.



Skip Shift



Currently, the Cadillac CTS-V, Pontiac GTO, Chevrolet Corvette and Camaro SS (other models may follow) equipped with the 6-speed manual



transmission have a feature referred to as a "skip-shift." This feature only allows a shift from 1st to 4th gear when the indicator lamp is illuminated



on the dash. Dealers cannot disable this feature as it was established to help meet fuel economy standards. The conditions for this feature are:



engine coolant at normal operating temperature, vehicle speed of 24-31 km/h (15-19 mph), 21% or less throttle being used (refer to Service

Conditions for Clearing the DTC



The DTCs are Type C DTCs.



Diagnostic Aids



* This diagnostic uses a comprehensive approach to the diagnosis of the KR31 auxiliary coolant pump relay and its related circuits. The



auxiliary coolant pump relay is a printed circuit board (PCB) relay. The relay is an integral component to the underhood bussed electrical



center (UBEC). It cannot be removed and it is not visible.



* Much of the diagnosis is performed at the ECM connectors. Great care should be taken to ensure that the correct terminals are tested and the



proper test probes are utilized when performing this diagnostic.



* The test lamp is used to provide a visual aid to observe the integrity of the KR31 relay, the UBEC and the relay control circuit.



* Grounding terminal X2-58 activates the powertrain relay, which will supply power through KR31 relay coil and the relay control circuit.



Under normal circumstances the test lamp will illuminate with dim intensity due to the load created by the KR31 relay coil. If the test lamp



does not illuminate, or illuminates brightly a condition exists in the KR31 relay control circuit or the UBEC.

- Mass Air Flow (MAF) Sensor Circuit



DTC P0102



- Mass Air Flow (MAF) Sensor Circuit Low Frequency



DTC P0103



- Mass Air Flow (MAF) Sensor Circuit High Frequency



Diagnostic Fault Information



Circuit/System Description



The mass air flow (MAF) sensor is located in the air intake duct. The MAF sensor is an airflow meter that measures the amount of air that enters the



engine. The MAF sensor uses a hot film that is cooled by air flowing past the sensing film as air enters the engine. The amount of cooling is



proportional to the amount of the air flow. As the air flow increases, more current is required in order to maintain the hot film at a constant



temperature. The engine control module (ECM) uses the MAF sensor in order to provide the correct fuel delivery for all operating conditions.



Conditions for Running the DTC



* The ignition is ON, or the engine is operating.



* The ignition voltage is greater than 10 V.



* DTC P0100, P0102 and P0103 run continuously once the above conditions are met for 1 s.

Circuit/System Description



The engine control module (ECM) controls boost using the turbocharger wastegate solenoid valve. The wastegate valve is actuated by a rod from



the diaphragm box located at the housing. A spiral spring in the diaphragm box works in the closing direction while the pressure in the diaphragm



works in the opening direction. The ECM supplies a pulse width modulation (PWM) signal to a solenoid valve, which then allows pressure from



the turbo to come through. When the pressure overcomes the spring force in the diaphragm box, the rod begins to move, opening the wastegate



valve to a corresponding degree. The ECM changes wastegate valve opening by varying the PWM signal, which regulates the turbine speed.



Ignition voltage is supplied directly to the wastegate solenoid valve. The ECM controls the solenoid valve by grounding the control circuit with a



solid state device called a driver. The driver is equipped with a feedback circuit that is pulled-up to a voltage. The ECM can determine if the control



circuit is open, shorted to ground, or shorted to a voltage by monitoring the feedback voltage.



Conditions for Running the DTCs



* The engine speed is greater than 80 RPM.



* The battery voltage is between 10-18 V.



* The ECM has commanded the wastegate solenoid valve ON and OFF at least once during the ignition cycle.



* The DTCs run continuously within the enabling conditions.



Conditions for Setting the DTCs



P0244



The ECM detects the wastegate solenoid valve control circuit is open.



P0245



The ECM detects the wastegate solenoid valve control circuit is shorted to ground.



P0246



The ECM detects the wastegate solenoid valve control circuit is shorted to voltage.



Action Taken When the DTCs Set



DTCs P0244, P0245, P0246 are Type B DTCs.



Conditions for Clearing the MIL/DTCs



DTCs P0244, P0245, P0246 are Type B DTCs.

Diagnostic Fault Information



Circuit/System Description



The clutch pressure (PC) solenoid 2 is part of the control solenoid valve assembly, which has no serviceable components. The normally high clutch



PC solenoid 2 regulates and directs the clutch PC solenoid 2 oil pressure to the 3-5 reverse clutch regulator valve and 3-5 reverse clutch boost



valve. Increasing clutch PC solenoid 2 pressure increases pressure to the 3-5 reverse clutch. The TCM varies the current to the PC solenoid 2



through a low side driver. Decreasing the current to the clutch PC solenoid 2 increases clutch PC solenoid 2 oil pressure by closing OFF the



solenoid exhaust port. Increasing the current to the clutch PC solenoid 2, decreases clutch PC solenoid 2 oil pressure by opening the solenoid



exhaust port. Clutch PC solenoid 2 power is supplied by the TCM through a high side driver (HSD). The HSD protects the circuit and components



from excessive current flow. If excessive current flow is detected, the HSD will turn OFF. When the fault is corrected, the HSD will reset.

DTC P0817



- Brake Transmission Shift Interlock Solenoid Actuator



Diagnostic Fault Information



Circuit/System Description



The transmission range switch is an integral part of the transmission control module (TCM). As the gear range selector lever is moved, the state of



the starter inhibit circuit may change, causing the circuit to open or close. An open circuit indicates a drive range and a low voltage signal, 0 V, at



the body control module (BCM). A closed circuit indicates PARK or NEUTRAL and a high voltage, 12 V, signal at the BCM. The BCM uses the



starter inhibit circuit status from the TCM in order to enable starter operation.

DTC P0970



- Clutch Pressure Control (PC) Solenoid 3 Control Circuit Low Voltage



DTC P0971



- Clutch Pressure Control (PC) Solenoid 3 Control Circuit High Voltage



Diagnostic Fault Information



Circuit/System Description



The clutch pressure (PC) solenoid 3 is part of the control solenoid valve assembly, which has no serviceable components. The normally high clutch



PC solenoid 3 regulates and directs the clutch PC solenoid 3 oil pressure to the R1/4-5-6 clutch regulator valve and 4-5-6 clutch boost valve.



Increasing clutch PC solenoid 3 oil pressure increases oil pressure to the low and reverse clutch or the 4-5-6 clutch, depending on the position of



the clutch select valve 2. The TCM varies the current to the PC solenoid 3 through a low side driver. Decreasing the current to the clutch PC



solenoid 3 increases clutch PC solenoid 3 oil pressure by closing OFF the solenoid exhaust port. Increasing the current to the clutch PC solenoid 3,



decreases clutch PC solenoid 3 oil pressure by opening the solenoid exhaust port. Clutch PC solenoid 3 power is supplied by the TCM through a



high side driver (HSD). The HSD protects the circuit and components from excessive current flow. If excessive current flow is detected, the HSD



will turn OFF. When the fault is corrected the HSD will reset.

Diagnostic Fault Information



Typical Scan Tool Data



Circuit Description



The heated oxygen sensors (HO2S) are used for fuel control and catalyst monitoring. Each HO2S compares the oxygen content of the surrounding



air with the oxygen content of the exhaust stream. When the engine is started, the control module operates in an Open Loop mode, ignoring the



HO2S signal voltage while calculating the air-to-fuel ratio. The control module supplies the HO2S with a reference, or bias voltage of about 450



mV. While the engine runs, the HO2S heats up and begins to generate a voltage within a range of 0-1,000 mV. This voltage will fluctuate above



and below the bias voltage. Once sufficient HO2S voltage fluctuation is observed by the control module, Closed Loop is entered. The control



module uses the HO2S voltage to determine the air-to-fuel ratio. An HO2S voltage that increases above bias voltage toward 1,000 mV indicates a



rich fuel mixture. An HO2S voltage that decreases below bias voltage toward 0 mV indicates a lean fuel mixture.



The heating elements inside each HO2S heat the sensor to bring the sensor up to operating conditions faster. This allows the system to enter Closed



Loop earlier and the control module to calculate the air-to-fuel ratio sooner.



Conditions for Running the DTCs

Diagnostic Fault Information



Circuit/System Description



The transmission fluid pressure (TFP) switch 4 is part of the control solenoid valve assembly which has no serviceable parts. The TCM supplies a



signal circuit to the TFP switch 4. The TFP switch 4 has an internal case ground. TFP switch 4 is normally closed or LOW. When oil pressure is



present at the TFP switch 4, the switch is open or HIGH. The normally LOW pressure control solenoid 5 controls pressure to the 1-2-3-4 clutch



regulator valve. The TCM monitors the TFP switch 4 to determine the position of the 1-2-3-4 clutch regulator valve. When the 1-2-3-4 clutch is



commanded OFF, pressure is present on the TFP switch 4. When the 1-2-3-4 clutch is commanded ON, the 1-2-3-4 clutch regulator valve moves



and pressure to the TFP switch 4 is exhausted through the 1-2-3-4 clutch regulator valve.
