Torque Converter Stall Test Conclusion

TORQUE CONVERTER STALL TEST CONCLUSION
1. Stall speed is too high in both "D" and "R" ranges
^ Low line pressure
^ Low & reverse brake (B) slippage
2. Stall speed is to high in "D" range only
^ Underdrive clutch (C) slippage
3. Stall speed is too high in "R" range only
^ Reverse clutch (A) slippage





4. Stall speed too low in both "D" and "R" ranges
^ Malfunction of torque converter (D)
^ Insufficient engine output

HYDRAULIC PRESSURE TEST
1. Warm up the engine until the automatic transaxle fluid temperature is 80 - 100°C.
2. Jack up the vehicle so that the wheels are free to turn.
3. Connect the special tool (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 diagnosis table.
