А что показывает сталл-тест? И что должно происходить или чего не должно происходить

CONVERTER STALL TEST
Stall testing involves determining maximum engine rpm obtainable at full throttle with the rear wheels locked and the transmission in D range. This test checks the holding ability of the converter overrunning clutch and both of the transmission clutches. When stall testing is completed, refer to the Stall Speed Specifications chart and Stall Speed Diagnosis guides.

WARNING: NEVER ALLOW ANYONE TO STAND DI- RECTLY IN LINE WITH THE VEHICLE FRONT OR REAR DURING A STALL TEST. ALWAYS BLOCK THE WHEELS AND APPLY THE SERVICE AND PARKING BRAKES DURING THE TEST.
STALL TEST PROCEDURE
(1) Connect tachometer to engine. Position tachom- eter so it can be viewed from driver seat.
(2) Check transmission fluid level. Add fluid if nec- essary.
(3) Start and run engine until transmission fluid reaches normal operating temperature.
(4) Block front wheels.
(5) Fully apply service and parking brakes.
(6) Open throttle completely for no more than five
seconds and record maximum engine rpm registered on tachometer.
CAUTION: Stall testing causes a rapid increase in transmission fluid temperature. Do not hold the throttle open any longer than five seconds. If more than one stall test is required, run the engine at 1000 rpm with the transmission in Neutral for at least 20 seconds to cool the fluid.
(7) If engine speed exceeds maximum shown in stall speed chart, release accelerator immediately. This in- dicates that transmission clutch slippage is occurring.
(8) Shift transmission into Neutral. Operate engine for 20 seconds. Stop engine, shift transmission into Park and release brakes.
(9) Stall speeds should be in 1800-2100 rpm range.
STALL TEST ANALYSIS
STALL SPEED TOO HIGH
If the stall speed exceeds specifications by more than 200 rpm, transmission clutch slippage is indicated.
STALL SPEED TOO LOW
Low stall speeds with a properly tuned engine indi- cate a torque converter overrunning clutch problem. The condition should be confirmed by road testing prior to converter replacement.
The converter overrunning clutch is slipping when: Stall speeds are 250 to 350 rpm below specified mini- mum and the vehicle operates properly at highway speeds but has poor low speed acceleration.
STALL SPEED NORMAL
If stall speeds are normal but abnormal throttle opening is required to maintain highway speeds, the converter overrunning clutch is seized and the torque converter must be replaced.
CONVERTER NOISE DURING TEST
A whining noise caused by fluid flow is normal during a stall test. However, loud metallic noises indicate a damaged converter. To confirm that noise is originating from the converter, operate the vehicle at light throttle in Drive and Neutral on a hoist and listen for noise coming from the converter housing.
