What are the causes of Skoda Kodiaq transmission failure?

The main cause of computer damage is sensor failure. Replacing it with a new sensor can solve the problem. Here is a related introduction about the transmission: Main functions: Changing the transmission ratio to expand the range of torque and speed variation of the driving wheels to adapt to frequently changing driving conditions, while allowing the engine to operate under favorable conditions. It enables the vehicle to reverse when the engine's rotation direction remains unchanged. By using neutral gear, it interrupts power transmission, allowing the engine to start, shift gears, and facilitating gear changes or power output. Working principle: A manual transmission mainly consists of gears and shafts, achieving speed and torque variation through different gear combinations. An automatic transmission (AT) is composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque variation through hydraulic transmission and gear combinations.
I've encountered similar issues with cars before, and transmission problems are often caused by internal wear. Components like gears, clutches, and bearings gradually wear out or deform over time, especially with poor driving habits such as frequently flooring the throttle at low speeds or constantly shifting gears in traffic. If the transmission fluid becomes old or contaminated, its lubricating effectiveness significantly decreases. Accumulated metal shavings in the oil passages can jam rotating parts, leading to overheating and sluggish shifting. Symptoms include increased vibrations, loss of power when climbing hills, or clicking noises during gear changes. I recommend changing the fluid every 50,000 kilometers and conducting a thorough inspection for wear. If minor cracks are found, replace the parts promptly—don't wait until the entire transmission fails. Drive more relaxed and maintain steady speeds to minimize wear issues.
I'm quite interested in automotive electronic control systems. The Skoda Kodiaq's transmission issues often stem from electronic components. It has a control unit called TCU, which relies on engine speed and vehicle speed sensor signals to shift gears. If the sensors age or wiring connectors loosen, the signals become chaotic, causing the TCU to misjudge actions, leading to erratic vehicle movement or failure to engage gears. For example, unstable battery voltage can affect the entire system, and software may respond sluggishly in low temperatures. When abnormalities are detected, use diagnostic tools to check fault codes. During troubleshooting, first inspect wiring tightness; if that doesn't work, consider upgrading the program or replacing small parts. In daily driving, avoid large fluctuations in RPM to prevent electronic interference.
