Pinpoint Tests
PINPOINT TEST A: SHIFT SOLENOIDS
PINPOINT TEST A: SHIFT SOLENOIDS|
Refer to Wiring Diagrams Cell 30 for schematic and connector information. Normal Operation and Fault Conditions The 10R80 transmission uses 6 linear force shift solenoids (A, B, C, D, E, F) called Casting Integrated Direct Acting Solenoids (CIDAS). Unlike previous shift solenoids, they are mechanical in nature meaning no transmission fluid passes through them. They use an armature pin assembly that moves a control valve in the main control valve body to control and apply hydraulic fluid pressure. Each clutch (A, B, C, D, E, F) has a corresponding shift solenoid (A, B, C, D, E, F) that is directly proportional in that zero current equals zero pressure and maximum current equals maximum pressure. Since there is no pressure with zero current, none of the clutch packs are able to engage if the power is interrupted to the shift solenoids . DTC Fault Trigger Conditions

PINPOINT TEST B: TRANSMISSION FLUID TEMPERATURE SENSOR|
Refer to Wiring Diagrams Cell 30 for schematic and connector information. Normal Operation and Fault Conditions The TFT sensor is a temperature dependent resistor that is in contact with transmission fluid in the transmission sump area. The PCM monitors the voltage drop across the TFT sensor, which changes as transmission fluid temperature varies. The PCM uses the TFT sensor signal as an input for its strategy for shifting and TCC operation. The PCM also uses the TFT sensor signal for transmission fault detection and diagnostics.

PINPOINT TEST C: TRANSMISSION RANGE SENSOR|
Refer to Wiring Diagrams Cell 30 for schematic and connector information. Normal Operation and Fault Conditions Shift by Wire The TR sensor is comprised of a dual set of TR sensors. On Shift by Wire vehicles, the park system position is detected by reading TR sensors A and B. The PCM shifts the vehicle in and out of park and provides forward or reverse based on the position of the GSM shift knob. The 10R60 transmission uses dual PWM output (at 125 Hz) TR sensors where: TR sensor A increases as the park system is moved from Park to Out of Park and TR sensor B decreases as the park system is moved from Park to Out of Park, together the sum of the two signals should add up to 100%.

PINPOINT TEST D: TSS, OSS, ISSA, ISSB SENSORS (ELECTRICAL)|
Refer to Wiring Diagrams Cell 30 for schematic and connector information. Normal Operation and Fault Conditions TSS Sensor The TSS sensor is a Hall-effect type sensor that provides a signal to the PCM that changes in frequency as the rotating speed of the planetary carrier No. 2 varies. The PCM compares the TSS sensor signal with the engine speed information to determine the amount of slip occurring in the torque converter. The PCM also compares the TSS sensor signal with the OSS sensor signal to determine the gear ratio provided by the planetary carrier No. 4. The PCM uses the TSS sensor signal as an input for its strategies for shifts, TCC operation and for transmission fault detection and diagnostics. OSS Sensor The OSS sensor is a Hall-effect type sensor that provides a signal to the PCM that changes in frequency as the rotating speed of the rear planetary carrier No. 4 varies. The PCM compares the OSS sensor signal with the TSS sensor signal to determine the gear ratio provided by the rear planetary gearset. The PCM also uses the OSS sensor signal as an input for its strategies for shifts, TCC operation and for transmission fault detection and diagnostics. Intermediate Shaft Speed A and B Sensors The Intermediate Shaft Speed A (ISSA) and B (ISSB) sensors are Hall-effect type sensors that provide a signal to the PCM that changes in frequency as the rotating speed of the component being monitored changes. ISSA monitors the speed and rotational direction of ring gear 1 and ISSB monitors the speed and rotational direction of planetary carrier-1/ring gear 4. The Intermediate shaft speed sensors are used to monitor clutch states for transmission fault detection and diagnostics. DTC Fault Trigger Conditions

Is DTC P1711 present in the PCM ?
|
PINPOINT TEST AB: DTC P0218, P1783|
Normal Operation and Fault Conditions The TFT sensor is a temperature dependent resistor that is in contact with transmission fluid in the transmission sump area. The PCM monitors the voltage drop across the TFT sensor, which changes as transmission fluid temperature varies. If the PCM detects an over temperature condition, it will set a DTC , and may limit engine torque to prevent further overheating. DTC Fault Trigger Conditions

Are any TFT sensor circuit diagnostic trouble codes (DTCs) present?
|
PINPOINT TEST AC: P179D|
Normal Operation and Fault Conditions Vehicles with a 10R transmission should not be towed in neutral with the engine off and the drive tires on the ground. When the engine is off, there is no transmission fluid flow in the transmission, and therefore no lubrication. This will lead to internal transmission damage if the vehicle is towed in neutral with the engine off. In case of emergency, the vehicle may be towed in this manner, only up to 55 kph (35 mph) for a distance up to 80 km (50 miles). DTC Fault Trigger Conditions

PINPOINT TEST AD: DTC P1A02|
Normal Operation and Fault Conditions The PCM monitors the low one-way clutch application. The low one-way clutch locks to prevent sun gear 1 from rotating backward in gears 1A and 2A. DTC Fault Trigger Conditions

|
PINPOINT TEST AF: DTC P27B2, P27B3, P27B4, P27B5, P27B6|
Normal Operation and Fault Conditions The PCM monitors the TSS , OSS , ISSA and ISSB sensors to verify the achieved gear matches the selected gear. If the PCM detects a reverse gear when a forward gear is selected, a forward gear when reverse is selected, an incorrect gear ratio or a mismatch between speed sensors, it will set a DTC .

Check
NOTE: Wheel-to-hub optimization is important. Clearance between the wheel and hub can be used to offset or neutralize the Road Force® or run-out of the wheel and tire assembly. For every 0.001 inch of wheel-to-hub clearance, the Road Force® can be affected between 1 and 3 pounds depending on the tire stiffness.
NOTE: The example below illustrates how the clearance between the wheel and the hub can be used to offset the high spot of radial run-out or Road Force®. Following the procedure will make sure of the best optimization.
Position the wheel and tire assembly on the vehicle so that the high spot location of radial run-out or Road Force® is at the 6 o'clock position and
