Stall Speed Test

  1. Start engine and allow it to reach normal operating temperature. Apply both parking and service brakes. Stall test is made in all Drive ranges and Reverse at WOT throttle position.
  2. Stall speed test checks engine performance, converter operation or installation and holding ability of the direct clutch, reverse clutch and low-intermediate band brake and gear train one-way clutch. See appropriate STALL SPEED SPECIFICATIONS  .
    CAUTION: While performing this test, DO NOT hold throttle open for more than 5 seconds at a time.
  3. After test, move gear selector lever to "N" and run engine at 1000 RPM for about 15 seconds to cool converter before making next test. If engine speed recorded by tachometer exceeds maximum limits given in specifications, RELEASE ACCELERATOR IMMEDIATELY because clutch or band slippage is indicated. See STALL SPEED TEST RESULTS  .
