What are the symptoms of transmission failure in the Volkswagen Touran?
1 Answers
Transmission failures generally manifest in the following ways: 1. Difficulty in shifting gears and a sense of jerking: During startup or driving, shifting gears feels stiff and laborious, as if something is obstructing, accompanied by jerking, vibration, and a sense of hesitation. Sometimes, shifting gears is easier when the car is cold but difficult when the car is warm, causing significant discomfort. The reason is that the relevant gears and components inside the transmission do not receive sufficient lubrication, failing to form a durable lubricating film, which prevents the components from operating smoothly. 2. Automatic transmission jerking and impact sensation: The car lacks power during startup, and there is noticeable jerking and hesitation at low or medium speeds, accompanied by fluctuations in the tachometer needle on the dashboard. When the accelerator pedal is pressed hard during medium to high-speed driving, the car slips, the tachometer needle rises rapidly, and there is a distinct impact sensation. Shifting from P to R or D gear results in a noticeable impact sensation and jerking. The cause is the presence of impurities inside the transmission, forming blockages in the valve body, hindering its smooth movement and preventing proper regulation of oil pressure, leading to jerking and shifting impact issues. 3. Transmission noise and loud sounds: During idling, driving, or high-load driving, abnormal noises or even loud sounds are heard from the transmission, along with irregular, dull sounds during gear shifting. The reason is contamination inside the transmission, wear or severe wear of bearings, gears, or other components, or damage to the gear sides.
