DIAGNOSTIC RESPONSE:DNS, Lock in Neutral CIRCUIT DESCRIPTION:The Transmission Control Module (TCM) uses input from the turbine speed and output speed sensors to determine the current commanded for steady-state gear ratio. The TCM then compares the known gear ratio to the calculated gear ratio for the current range. CONDITIONS FOR RUNNING THE DTC:1. Hydraulic system is pressurized.2. No shift in progress.3. Hydraulic default condition not present.4. Output speed is above 200 rpm.5. Engine initialization or shutdown is not in process. CONDITIONS FOR SETTING THE DTC:DTC P0736 sets during steady-state condition when the calculated reverse (R1) gear ratio differs from the known...

DIAGNOSTIC RESPONSE:None CIRCUIT DESCRIPTION:The Transmission Control Module (TCM) uses data received from the engine speed sensor and the turbine speed sensor to calculate torque converter slip value. The TCM then compares this calculated slip value to a preset value in the TCM calibration. CONDITIONS FOR RUNNING THE DTC:1. Hydraulic system is pressurized.2. Hydraulic default condition not present.3. Engine initialization or shutdown is not in process.4. Selected range is a forward range.5. Throttle position is 50% or more.6. Transmission fluid temperature is between 25°C (77°F) and 130°C (266°F).7. Six or more seconds have elapsed since Torque Converter Clutch (TCC) was applied...

DIAGNOSTIC RESPONSE:DNS CIRCUIT DESCRIPTION:The Transmission Control Module (TCM) uses data received from the engine speed sensor and the turbine speed sensor to calculate torque converter slip value. The TCM then compares this calculated slip value to a preset value in the TCM calibration. CONDITIONS FOR RUNNING THE DTC:1. Hydraulic system is pressurized.2. Hydraulic default condition not present.3. Number of drive cycles more than 10 since last test.4. Neutral or Neutral Very Low (NVL) attained.5. C5 clutch pressure command not changing.6. Output speed less than 50 rpm when throttle position is less than 15%.7. Engine speed less than 450 rpm when...

DIAGNOSTIC RESPONSE:DNS, RPR CIRCUIT DESCRIPTION:The Transmission Control Module (TCM) uses input from the turbine speed and output speed sensors to determine the current commanded for steady-state gear ratio. The TCM then compares the known gear ratio to the calculated gear ratio for the current range. This DTC test determines if the on-coming clutch controlled by Pressure Control Solenoid 2 (PCS2) engages during a forward range shift. PCS2 controls the C2 clutch for 4th through 5th gears and C3 clutch for Reverse or Reverse 2. PCS2 also controls C3 clutch in the 3700 model for Low range. CONDITIONS FOR RUNNING THE...

DIAGNOSTIC RESPONSE:DNS, RPR CIRCUIT DESCRIPTION:The Transmission Control Module (TCM) uses input from the turbine speed and output speed sensors to determine the current commanded for steady-state gear ratio. The TCM then compares the known gear ratio to the calculated gear ratio for the current range. This DTC test determines if the off-going clutch controlled by Pressure Control Solenoid 2 (PCS2) remains engaged during a forward range shift. PCS2 controls the C2 clutch for 4th through 5th gears and C3 clutch for Reverse or Reverse 2. PCS2 also controls C3 clutch in the 3700 model for Low range. CONDITIONS FOR RUNNING...
