Apply the service brakes and start the engine.Note: To ensure that the transmission oil does not overheat, do not keep the torque converter in a full stall condition for more than 30 seconds. After the torque converter is stalled, shift the transmission direction and speed control to NEUTRAL and operate the engine at 1200 rpm to 1500 rpm in order to cool the oil.
Disengage the parking brake. Shift the transmission direction and speed control to FOURTH SPEED FORWARD and fully depress the accelerator pedal. Allow the engine rpm to stabilize. Then, observe the tachometer.The correct stall speed is 2010 65 rpm.Stall speeds that are low indicate incorrect engine performance. Stall speeds that are high indicate incorrect performance of the transmission or of the torque converter. If you must repeat the test, keep the transmission in neutral and wait for two minutes between tests.Reference: For more information about troubleshooting the transmission and the torque converter, refer to Testing And Adjusting, "Power Train Troubleshooting".
