Judder upon torque converter clutch (TCC) operation

DESCRIPTION

  • Vehicle jolts when TCC is engaged.

POSSIBLE CAUSE

  • Poor TCC engagement due to either slippage because the TCC is stuck or the line pressure is low.

    1. TCC piston slippage, burnt

      • Line pressure low

      • Shift solenoid A malfunction

      • Shift solenoid E malfunction

      • Control valve body malfunction

      • Body ground malfunction

      • Pressure control solenoid A malfunction

    2. Signal malfunction

      • VSS malfunction

      • Sensor ground malfunction

      • TFT sensor malfunction

      • APP sensor malfunction

      • Input/turbine speed sensor malfunction

      • CKP sensor malfunction

    3. Torque converter malfunction

CAUTION:

  • If the TCC is stuck, inspect it. In addition, inspect the oil cooler for foreign particles which may have mixed in with the ATF.

NOTE:

  • Before following the troubleshooting steps, make sure that the Automatic Transaxle ON-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted..


Diagnostic procedure

STEP

INSPECTION

ACTION

1

Inspect the TSS PID value using the M-MDS.

(See ON-BOARD DIAGNOSTIC SYSTEM PID/DATA MONITOR INSPECTION [FS5A-EL].)

Is the PID value normal?

Yes

Go to the next step.

No

Repair or replace any malfunctioning parts.

2

Disconnect the TCM connector.

Measure the resistance between ground terminal at the TCM connector and body ground.

Is the resistance less than 5.0 ohms

?

Yes

Go to the next step.

No

Repair or replace the wiring harness for a possible open circuit.

3

Measure the resistance between shift solenoid A and E control circuit at the TCM connector and control valve body connector.

Measure the resistance between shift solenoid A/E circuit at the TCM connector and control valve body connector.

Are the resistances less than 5.0 ohms

?

Yes

Go to the next step.

No

Repair or replace the shift solenoid A and/or E circuit.

4

Inspect the shift solenoid.

(See SOLENOID VALVE INSPECTION [FS5A-EL].)

Is the solenoid valve operating properly?

Yes

Go to the next step.

No

Overhaul the control valve body and repair or replace any malfunctioning parts.

(See Automatic Transaxle Workshop Manual FS5A-EL.)

If any problem remains:

  • Overhaul the transaxle and repair or replace any malfunctioning parts.

    (See Automatic Transaxle Workshop Manual FS5A-EL.)

5

Inspect the TCM PID LPS value using the M-MDS.

(See ON-BOARD DIAGNOSTIC SYSTEM PID/DATA MONITOR INSPECTION [FS5A-EL].)

Is the PID value normal?

Yes

Overhaul the control valve body and repair or replace any malfunctioning parts.

(See Automatic Transaxle Workshop Manual FS5A-EL.)

If any problem remains:

  • Overhaul the transaxle and repair or replace any malfunctioning parts.

    (See Automatic Transaxle Workshop Manual FS5A-EL.)

No

Replace the TCM.

(See TCM REMOVAL/INSTALLATION [FS5A-EL].)

6

  • Verify the test results.

    • If normal, return to the diagnostic index to service any additional symptoms.

    • If the malfunction remains, inspect the related Service Bulletins and/or On-line Repair Information and perform repair or diagnosis.

      • If the vehicle is repaired, troubleshooting is completed.

      • If the vehicle is not repaired or additional diagnostic information is not available, replace the TCM..
