Stall Test

STALL TEST
This test is to check overall performance of automatic transmission and engine by measuring stall speed at "D" and "R" ranges. Be sure to perform this test only when transmission fluid is at normal operating temperature and its level is between FULL HOT and LOW HOT.

CAUTION: Do not run engine at stall more than 5 seconds continuously, for oil temperature may rise excessively high.

1. Install tachometer.
2. Apply parking brake and block vehicle wheels.
3. Start engine with selector lever shifted to "P" range.
4. Depress brake pedal.
5. Shift selector lever to "D" range and depress accelerator pedal fully while watching tachometer. Read engine rpm quickly when it has become constant (stall speed).
6. Release accelerator pedal immediately after stall speed is checked.
7. In the same way, check stall speed at "R" range.
8. Stall speed should be within following specification.

Stall speed: 2,300 - 2,800 r/min





9. Possible causes for out-of-specification stall speed are as shown. Check each part which is suspected to be the cause.
