Gearbox much impact solutions do not blindly self-study

My car has a greater driving 25,000 kilometers , I recently discovered the cold start to heat the car, when the engine reaches 1000 rpm , the brakes tight , the resistance to hang D block start large hanging block when R : owner Wong sense of shock . Is that why?

Expert visits : automatic models , Guadang theoretically will have a sense of shock , D block and R block the same. If they are feeling the impact of the different , there may be different before and after the shock pad engine and gearbox damaged layer of the internal failure. Further , there may be a greater sense of shock caused by the engine speed is too high , the digimaster 3 transmission power transmitted by the engine rotational speed is determined .

Abnormal sound

Owner Mr. Zhao : In recent days, when my car cool car started feeling blah in the vicinity of the A-pillar has a voice , launch x431 diagun iii especially in the bumpy road , the sound is particularly great. After the car is hot, the sound disappears , is this what is the reason ? Is not too low temperatures caused it?

Expert visits : If sound and temperature changes related impact on应属cold engine valve train , this response is increased with cold cars with mileage ( about 5-10 million kilometers) , and the gradual emergence , but also the normal natural abnormal noise occurs during wear . Also, according to Mr. Zhao said , the bumpy road , the sound particularly large, there may be caused by loose parts near the A-pillars , regardless of temperature.
