TORQUE CONVERTER

The torque converter, as the power plant which delivers the power of engine to the automatic transaxle, consists of 3 elements, 2 phases and 1 stage type.

Scheme 1

Scheme 1: TORQUE CONVERTER
  1. The flowing section form of the torque converter changes the round type to the flat type to reduce the length of the torque converter.
  2. The maximum operating degree of the damper clutch installed inside the transaxle increases from 12° to 18° to improve the engine revolution change reduction capability and the fuel consumption

TORQUE CONVERTER STALL TEST

This test measures the maximum engine speed when the select lever is at the "D" or "R" position and the torque converter stalls to test the operation of the torque converter, starter motor and one-way clutch operation and the holding performance of the clutches and brakes in the transmission.

CAUTIONDo not let anybody stand in front of or behind the vehicle while this test Is being carried out.
  1. Check the automatic transmission fluid level and temperature and the engine coolant temperature. Fluid level: At the HOT mark on the oil level gauge Fluid temperature: 80~100°C (176~212°F) Engine coolant temperature: 80~100°C (176~212°F)
  2. Check both rear wheels (left and right).
  3. Pull the parking brake lever on, with the brake pedal fully depressed.
  4. Start the engine.
  5. Move the select lever to the "D" position, fully depress the accelerator pedal and take a reading of the maximum engine speed at this time. CAUTION: The throttle should not be left fully open for any more than eight seconds. If carrying out the stall test two or more times, move the select lever to the "N" position and run the engine at 1,000 r/min to let the automatic transaxle fluid cool down before carrying out subsequent tests. Move the select lever to the "R" position and carry out the same test again.

Scheme 2: HYDRAULIC PRESSURE TEST
  1. Warm up the engine until the automatic transaxle fluid temperature is 80-100°C (176-212°F).
  2. Jack up the vehicle so that the wheels are free to turn.
  3. Connect the special tools (09452-21500, 09452-21000) oil pressure gauge to each pressure discharge port.
  4. Measure the hydraulic pressure at each port under the conditions given in the standard hydraulic pressure table, and check that the measured values are within the standard value ranges.
  5. If a value is outside the standard range, correct the problem while referring to the «HYDRAULIC PRESSURE TEST»(ref-270461-S39113209072007110600000) diagnosis table.

Stall test procedure in D1 and reason Procedure Warm up the engine. After positioning the select lever in "D", depress the foot brake pedal fully after that, depress the accelerator pedal to the maximum. * The slippage of 1st gear operating parts can be detected by stall test in D Reason for stall test If there is no mechanical defaults in A/T, every slippage occur in torque converter. Therefore, engine revolution is output, but input and output speed revolution must be "zero" due to wheel's lock. If 1st gear operating part has faults, input speed revolution will be out. If output speed revolution is output. It means that the foot brake force is not applied fully. Remeasuring is required.

Check the A/T fluid level and temperature and the engine coolant temperature. Fluid level: At the hot mark on the oil level gauge. Fluid temperature: 176°F~212°F (80~100°C). Engine coolant temperature: 176°F~212°F (80~100°C). Chock both rear wheel (left and right). Pull the parking brake lever on with the brake pedal fully depressed. The throttle should not be left fully open for more than eight second. If carrying out the stall test two or more time, move the select lever to the "N" position and run the engine at 1,000 RPM to let the A/T fluid cool down before carrying out subsequent.
