TIGHTENING TORQUE SPECIFICATION

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 1stage type.

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 11° 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.

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.

Stall rpm : 2,000~2,700 RPM
