Why doesn't the Nissan Sylphy automatic transmission shift gears?
1 Answers
Nissan Sylphy automatic transmission not shifting gears may be due to the following reasons: Engine malfunction: Slight shifting impact may be normal, but if the impact is more noticeable, it is recommended to check the engine's working condition at a repair station and then inspect whether there is a fault in the transmission. Oil passage blockage: If the transmission oil is inadequate or the oil passage is blocked, the pressure in the hydraulic cylinder cannot rise, making gear shifting impossible. Normally, the oil should be changed every 60,000 kilometers, preferably using a circulating machine. Another point to mention: especially for some older cars, even if the oil has been changed as required, if the transmission oil pan has never been removed, the filter screen and filter element inside may be completely blocked, which can also lead to insufficient hydraulic pressure. It is recommended to remove the transmission oil pan of older cars to check its condition.
