Circuit/System Verification
1. Ignition ON, observe the DTC information with a
scan tool.
2. Record Freeze Frame and Failure Records.
3. Clear DTC's.
4. Operate the vehicle under the conditions observed in
the Failure Records.
5. Observe the DTC information with the scan tool.
Verify that the DTC does not set.
Circuit/System Testing
1. Ignition OFF, disconnect the 22-way automatic
transmission (AT) wiring harness connector (C2) at
the TCM.
2. Test for 11-24 Ω of resistance between the shift
solenoid control circuit terminal (harness side) and
ground.
➢ If not within the specified range
– Remove the appropriate solenoid and test for 11-
24 Ω of resistance.
➢ If not within the specified range, replace the valve
body assembly.
– Replace the AT wiring harness, refer to "Wiring
Harness Removal" procedure and "Wiring
Harness Installation" procedure.
3. At the TCM, connect a test lamp between the shift
solenoid high control circuit and the ground.
4. Command the shift solenoid ON and OFF with a
scan tool. The test lamp should turn ON and OFF
when changing between the commanded states.
➢ If the test lamp does not follow the commanded
states, replace the TCM, refer to "Transmission
Control Module Removal" and "Transmission
Control Module Installation" procedure.
Component Testing
Test the shift solenoid, at 20°C, for 11-16 Ω of resistance
between the control circuit terminal and its case ground.
➢ If not within the specified range, replace the
solenoid.

DTC Descriptor
DTC P1719: Torque Delivered Signal - Unusual Shifting
Circuit/System Description
The transmission control module (TCM) calculates last
shift status based on data from the input and output
speed sensors. The TCM measures the amount of time
required to complete each shift.
Conditions for Running the DTC
• No Throttle Position (TP) Sensor DTC P0120
• No Transmission Range (TR) Switch DTC's P0706,
P0707, or P0708
• No Transmission Fluid Temperature (TFT) Sensor
DTC's P0711, P0712, or P0713
• No Speed Sensor DTC's P0717, P0722, P0727
• No Pressure Control (PC) Solenoid DTC's P0962,
P0963, P0966, P0967, P0970, or P0971
• No Shift Solenoid (SS) Control Circuit DTC's P0973,
P0974, P0976, P0977, P0979, P0980, P0982, P0983,
P0985, or P0986
• No Transmission Torque Delivered Circuit DTC P2637
• No Communications DTC's U0100 or U2104
• Transmission fluid temperature (TFT) is greater than
60°C
• Engine speed is greater than 400 RPM
• Shift range equals D, M, or L
• Ignition voltage is greater than 10.5 volts
Conditions for Setting the DTC
The TCM commands a gear shift, and one of the
following occurs 5 times:
• Tie-up
• Engine flare
• Long shift time
• Rapid shifting
Action Taken When the DTC Sets
• DTC P1719 is a Type A DTC
• The transmission will operate in 5th gear in D range,
2nd in L range
• Limit engine torque to 150 N⋅m
