1. Check the starting of the car from the position «D1»
1. Drive the vehicle for approximately 10 minutes and warm up the engine oil and automatic transmission fluid to operating temperature.
Operating temperature of automatic transmission fluid: 50-80°С.
2. Stop the car on level ground.
3. Press the overdrive button (indicator «O/D OFF» does not burn).
4. Move the selector lever to position «R».
5. Start the engine.
6. Move the selector lever to position «D».
7. Accelerate the vehicle by depressing the accelerator pedal half way.
Using the CONSULT-II tester, read the gear range.
Does the car move out of position «D1»?
Yes - Go to step 2.
No - Continue with the road test.
2. Check upshifting (WITH «D1» on «D2»)
Press the accelerator pedal halfway and check if the automatic transmission shifts from «D1» on «D2» at a given speed.
See section «Vehicle speed at which the gear shift occurs»
Using the CONSULT-II tester
Check gear range, throttle angle and vehicle speed.
Does the automatic transmission shift from «D1» on «D2» at a given speed?
Yes - Go to step 3.
No - Continue road test
3. Check upshifting (With «D2» on «D3»)
Press the accelerator pedal halfway and check if the automatic transmission shifts from «D2» on «D3» at a given speed.
See section «Vehicle speed at which the gear shift occurs».
Using the CONSULT-II tester
Check gear range, throttle angle and vehicle speed.
Does the automatic transmission shift from «D2» on «D3» at a given speed?
Yes - Go to step 4.
No - Continue with the road test.
4. Check the upshift (With «D3» on ««D4»)
Press the accelerator pedal halfway and check if the automatic transmission shifts from «D3» on «D4» at a given speed.
See section «Vehicle speed at which the gear shift occurs».
Using the CONSULT-II tester
Check gear range, throttle angle and vehicle speed.
Does the automatic transmission shift from «D3» on «D4» at a given speed?
Yes - Go to step 5.
No - Continue with the road test.
5. Check blocking with «D4» on «D4 with lock»
Press the accelerator pedal halfway and check if the automatic transmission shifts from «D4» on «D4 with lock» at a given speed.
See section «Vehicle speed at which the gear changes».
Using the CONSULT-II tester
Check vehicle speed, throttle angle at lock 94%
Does the automatic transmission lock at a given speed?
Yes - Go to step 6.
No - Continue road test
6. Check lock hold
Using the CONSULT-II tester
Test hold on blocking 94%
Does the automatic transmission hold the lock state for more than 30 seconds?
Yes - Go to step 7.
No - Continue with the road test.
7. Check the release of the lock (With «D4 with lock» on «D4»)
Release the accelerator pedal.
Using the CONSULT-II tester
Check withdrawal at 4% blocking.
Does the lock release when the accelerator pedal is released?
Yes - Go to step 8.
No - Continue with the road test.
8. Check the downshift (With «D4» on «D3»)
Slow down the vehicle by lightly depressing the brake pedal.
Using the CONSULT-II tester
Read the gear range and vehicle speed.
Does the engine smoothly return to idle speed? when switching automatic transmission from «D4» on «D3»?
Yes -
- 1. Stop the car.
- 2. Go to p. «Check in motion - Part 2»
No - Continue with the road test.
