What are the symptoms of transmission failure in the Volkswagen Magotan?

[Robin]

The symptoms of transmission failure in the Volkswagen Magotan are as follows: 1. Inability to accelerate the vehicle. The characteristic is that the engine speed surges, but the vehicle speed increases very slowly. Or the engine speed rises when shifting gears. 2. There is a shock and jerking sensation when upshifting. That is, when shifting from P to D or R, a shock occurs, or during upshifting, the engine speed drops, and then rises again with the throttle. If a shock occurs at this time, it is also a transmission problem. 3. Locked gear. The transmission enters a protection mode. After a fault occurs in the transmission, the computer can detect it. The more high-end the car, the stronger the computer's detection capability. At this time, the computer will lock the transmission in third or fourth gear. 4. The secondary oxygen sensor will not correctly provide data to the vehicle computer, causing the air-fuel mixture concentration to become too lean or too rich. A too-lean mixture will cause ignition difficulties, weak driving, engine backfire, etc., while a too-rich mixture will increase fuel consumption, incomplete combustion, and severe carbon deposits in the cylinders and spark plugs.
