Inspection Procedure
6: Engine Stalls During Shifting
COMMENTS ON TROUBLE SYMPTOM
If the engine stalls when the selector lever is shifted from N to D or R range while the
engine is idling, the cause is probably a malfunction of the engine system, damper clutch solenoid
valve, valve body or torque converter (damper clutch).
PROBABLE CAUSES
Malfunction of engine system
Malfunction of damper clutch solenoid valve
Malfunction of valve body
Malfunction of torque converter (damper clutch)
Malfunction of the A/T-ECU
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-III actuator test
Item 06: Damper clutch solenoid valve
OK: Operating sound can be heard.
Q.
Is the check result normal?
Go to Step 2.
Replace the damper clutch solenoid valve.
STEP 2. Valve body disassembly clean and assembly
(1)Check the bolts for looseness and the O-ring, solenoid valve and valve body for
damage. Replace the valve body assembly if the damages are thought to be irreparable.
(2)Test drive the vehicle.
(3)Verify that the condition described by the customer exists.
Q.
Does a malfunction take place again?
Go to Step 3.
The inspection is complete.
STEP 3. Torque converter check
Check for damaged drive plate, incorrect installation in the input shaft (inserted at
an angle), damaged splines or damper clutch sealing.
Q.
Is the check result normal?
Go to Step 4.
If repair is possible, repair the damaged part. If repair is not possible because
the splines on the drive plate or torque converter are damaged, replace it.
