TIGHTENING TORQUE
TORQUE CONVERTER AND SHAFT
The torque converter consists of a impeller (pump), turbine and stator assembly in a single unit. The pump is connected to the engine crankshaft and turns as the engine turns. This drawing force is transmitted to the turbine through the oil which is recycled by the stator.
The transmission has two parallel shafts; the input shaft and the output shaft. Both shafts are in line with the engine crankshaft. The input shaft includes the overdrive clutch, reverse clutch, underdrive clutch, one way clutch, 2ND brake, low & reverse brake, overdrive planetary carrier, output planetary carrier and transfer drive gear. The output shaft includes the transfer driven gear.

Oil Temperature Sensor
The oil temperature sensor is of the thermistor type, and senses the automatic transaxle fluid temperature. Using the signal from this sensor, TCM (PCM) controls the shift pattern optimally during shift. In order to operate the damper clutch, this signal is also referred.
- Range of temperature : -40°C~145°C
- Type : Separated type (High / Low temperature)

TORQUE CONVERTER STALL TEST
This test measures the maximum engine speed when the selector lever is in the D or R position. The torque converter stalls to test the operation of the torque converter, starter motor, one-way clutch operation, the holding performance of the clutches, and brakes in the transaxle.
| CAUTION | Do not let anybody stand in front of or behind the vehicle while this test is being carried out |
- 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)
- Prevent all the wheels from moving during the test.
- Pull the parking brake lever up, with the brake pedal fully depressed.
- Start the engine.
- Move the selector lever to the "D" position, fully depress the accelerator pedal and take a reading of the maximum engine speed at this time. Stall speed : 2,100~2,900 RPM CAUTION: The throttle should not be left fully open for any more than five seconds. If carrying out the stall test two or more times, move the selector 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 selector lever to the "R" position and carry out the same test again.

- Stall speed is too high in both "D" and "R" ranges Low line pressure Low & reverse brake (B) slippage
- Stall speed is to high in "D" range only Underdrive clutch (C) slippage
- Stall speed is too high in "R" range only Reverse clutch (A) slippage
- Stall speed too low in both "D" and "R" ranges Malfunction of torque converter (D) Insufficient engine output
