What are the causes of transmission failure in the 2017 Passat?
2 Answers
If the Volkswagen Passat transmission makes abnormal noises, especially when shifting at low speeds with relatively minor sounds, it could be due to internal component wear during operation, which is a normal phenomenon. The specific cause can only be determined after a thorough inspection at a professional repair shop. Additional information about the transmission is as follows: 1. Introduction: A device that changes the speed ratio and direction of motion. Used in automobiles, tractors, ships, machine tools, and various machines to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. Gear-driven transmissions generally consist of a housing and several gear pairs. 2. Function: Under constant engine speed and torque, it changes the driving force and speed of the vehicle (shifting); allows the vehicle to reverse (direction change); and enables the engine to idle without stalling (neutral gear).
I also experienced transmission issues with my 2017 Passat. Honestly, slipping or jerking is quite common. The main culprit is likely a faulty mechatronic control unit—that thing handles shift logic and tends to fail over time. Oil seal leaks can lead to insufficient transmission fluid, and degraded fluid harms cooling performance. Malfunctioning sensors, like speed or temperature sensors, may send false signals. Additionally, delayed operation can stem from outdated or aging software. Worn parts, such as overused clutch plates, can also cause trouble. After driving this car for years, I’d stress that regular maintenance and fluid changes reduce failure rates. If problems arise, don’t delay—get it checked at a professional shop immediately. Never ignore safety risks.
