Torque Converter Diagnosis

Prior to installing a new torque converter, all diagnostic procedures must be followed. This is to prevent the unnecessary installation of new or remanufactured torque converters. Only after a complete diagnostic evaluation can the decision be made to install a new torque converter.

Begin with the normal diagnostic procedures as follows

  1. Preliminary Inspection.
  2. Know and Understand the Customer Concern.
  3. Verify the Concern - Carry out the «TORQUE CONVERTER OPERATIONS TEST»(ref-207762-S22882686192006030900000) .
  4. Carry out Diagnostic Procedures. Run on-board diagnostics. Refer to «ON-BOARD DIAGNOSTICS WITH DIAGNOSTIC TOOL»(ref-207762-S30269701422005120200000) . Repair all non-transaxle related DTCs first. Repair all transaxle DTCs. Rerun on-board diagnostic to verify repair. Carry out the Line Pressure Test. Refer to «LINE PRESSURE TEST»(ref-207762-S38988026062005120200000) . Carry out the Stall Speed Test. Refer to «STALL SPEED TEST»(ref-207762-S07237255702005120200000) . Carry out the Diagnosis by Symptom Index. Refer to «DIAGNOSIS BY SYMPTOM»(ref-207762-S42303105312005120200000) . Use the index to locate the appropriate routine that best describes the symptom(s). The routine will list all possible components that may cause or contribute to the symptom. Check each component listed; diagnose and repair as necessary before installing a new torque converter.

Torque Converter Operations Test

This test verifies that the torque converter clutch control system and the torque converter are operating correctly.

  1. Carry out the Quick Test. Refer to «ON-BOARD DIAGNOSTICS WITH DIAGNOSTIC TOOL»(ref-207762-S30269701422005120200000) . Check for DTCs. Refer to «DIAGNOSTIC TROUBLE CODE CHARTS»(ref-207762-S05026526682005120200000) .
  2. Connect a tachometer to the engine.
  3. Bring the engine to normal operating temperature by driving the vehicle at highway speeds for approximately 15 minutes in O/D position.
  4. After normal operating temperature is reached, maintain a constant vehicle speed of about 80 km/h (50 mph) and tap the brake pedal with the left foot.
  5. The engine rpm should increase when brake pedal is tapped, and decrease about 5 seconds after pedal is released. If this does not occur, refer to Torque Converter Operation Concerns in the «DIAGNOSIS BY SYMPTOM»(ref-207762-S42303105312005120200000) .
  6. If the vehicle stalls in O/D or manual 2 at idle with vehicle at a stop, move the position selector lever to manual 1 position. If the vehicle stalls, refer to Torque Converter Operation Concerns in «DIAGNOSIS BY SYMPTOM»(ref-207762-S42303105312005120200000) . Repair as necessary. If the vehicle does not stall in O/D position, refer to «DIAGNOSIS BY SYMPTOM»(ref-207762-S42303105312005120200000) .

Fluid Leakage in Torque Converter Area

In diagnosing and correcting fluid leaks in the pump support and gear and torque converter area, use the following procedures to locate the exact cause of the leakage. Leakage between the transaxle and engine, as evidenced by fluid around the torque converter housing, may have several sources. By careful observation it is possible, in many instances, to pinpoint the source of leakage before removing the transaxle from the vehicle. The paths which the fluid takes to reach the bottom of the torque converter housing are shown in the illustration. The five steps following correspond with the numbers in the illustration.

Scheme 10

Scheme 10: Fluid Leakage in Torque Converter Area
  1. Fluid leaking by the pump seal lip will tend to move along the impeller hub and onto the back of the impeller housing. Except in the case of a total seal failure, fluid leakage by the lip of the seal will be deposited on the inside of the torque converter housing only, near the outside diameter of the housing. Fluid from the vent assembly may move along the impeller hub and onto the back of the impeller housing. Fluid from a converter hub weld leak will move along a path on the inside of the converter housing.
  2. Fluid leakage by the outside diameter of the pump seal and pump body will follow the same path that leaks by the inside diameter of the pump seal follow. Fluid from a converter hub weld leak will move along a path on the inside of the converter housing.
  3. Fluid that leaks by a pump-to-case screw or pump gasket will be deposited on the inside of the torque converter housing only. Fluid will not be deposited on the back of the torque converter.
  4. Fluid leakage from the converter drain plug, (model-dependent) converter seal weld or converter-to-flexplate stud weld will appear at the outside diameter of the torque converter on the back face of the flexplate, and in the converter housing only near the flexplate. Fluid leaks from the torque converter will leave a ring of fluid around the inside of the torque converter housing.
  5. Engine oil leaks are sometimes incorrectly diagnosed as transaxle pump gasket leaks. The following areas of possible leakage should also be checked to determine if engine oil leakage is causing the concern. Leakage at the valve cover gasket may allow oil to flow over the torque converter housing or seep down between the torque converter housing and cylinder block causing oil to be present in or at the bottom of the torque converter housing. Oil galley plug leaks will allow oil to flow down the rear face of the cylinder block to the bottom of the torque converter housing. Leakage at the crankshaft rear oil seal will work back to the flexplate, and then into the torque converter housing.

ROUTINE 242/342 - TORQUE CONVERTER CLUTCH CONCERNS: CYCLING/SHUDDER/CHATTER

Torque Converter

  1. A new or remanufactured torque converter must be installed if one or more of the following statements is true: A torque converter malfunction has been determined based on complete diagnostic procedures. Converter stud or studs, impeller hub or bushing are damaged. Discoloration (due to overheating). Evidence of transmission assembly or fluid contamination due to the following transmission or converter failure Modes: Major metallic failure. Multiple clutches or clutch plate failures. Sufficient component wear which results in metallic contamination. Internal torque converter contamination present. For additional information, refer to «TORQUE CONVERTER CONTAMINATION INSPECTION»(ref-207762-S16866063842005120200000) .

Torque Converter Contamination Inspection

CAUTIONDo not use water-based cleaners or mineral spirits to clean or flush the torque converter or transmission damage will occur. Use only clean automatic transmission fluid designated for the transmission and converter being serviced.
CAUTIONThe torque converter drain plug and seal are not reusable. If equipped, discard the drain plug and seal, then install a new drain plug assembly.
  1. If a new or remanufactured torque converter is not being installed, the following steps must be completed.
  2. With the torque converter on a bench, pour a small amount of transmission fluid from the torque converter onto an absorbent white tissue or through a paper filter and examine the fluid.
  3. Observe the color and odor of the fluid. The fluid should be red, not brown or black. Odor may indicate an overheating condition such as clutch disc or band failure.
  4. Examine the stain on the tissue for evidence of particles (spec of any kind). Examine the fluid level indicator for signs of antifreeze (gum or varnish). If particles are present in the fluid or there is evidence of engine coolant or water, a new torque converter must be installed.
  5. If there are no particles or contamination present, drain the remainder of the transmission fluid from the torque converter.
  6. Add 1.9 liter (2 quarts) of clean automatic transmission fluid into the converter and agitate by hand.
  7. Thoroughly drain the fluid.
