3.3.4. Check of the hydrotransformer on completely slowed down car (Torque converter stall test)

The purpose of this check is measurement of the maximum frequency of rotation of a bent shaft of the engine at completely slowed down output shaft of the automatic transmission on ranges of "D" and "R". It is possible to determine operability of the obgonny coupling of the stator of the hydrotransformer, and also existence of pro-slipping in frictional couplings and brakes of the automatic transmission by the size of this frequency.

ATTENTION
During this check do not allow anybody to be in front of or behind the car.

Check the level and temperature of oil in the automatic transmission, and also temperature of cooling liquid of the engine.
Oil level in the automatic transmission (ATF): on mark "NOTES" of the masloizmeritelny probe.
Oil temperature in the automatic transmission (ATF): 80–100 °C.
Temperature of cooling liquid of the engine: 80–100 °C.
Establish brake shoes under back wheels of the car (left and right).
Completely lift the lever of the parking brake and squeeze out against the stop a brake pedal.
Start the engine.
Install the automatic transmission selector lever in situation "D", press against the stop a pedal of an accelerator and determine the frequency of rotation of a bent shaft of the engine at this moment.

ATTENTION
During this test do not hold a butterfly valve of completely open more than 8 pages.
If this test needs to be carried out more than once, then after each check transfer the automatic transmission selector lever to situation "N" and let's the engine work on the mines-1 mode 1000 within 2 min., for cooling of oil in the automatic transmission (ATF) between checks.
Nominal rate of frequency of rotation of the engine at completely slowed down car (stall test): 2100–2900 min.-1.
Transfer the selector lever to situation "R" and repeat check on completely slowed down car, to points which are similarly mentioned above.
Nominal rate of frequency of rotation of the engine at completely slowed down car (stall test): 2100–2900 min.-1.
