There are several potential causes of a clunking noise when shifting gears in a Volkswagen, according to transmission experts in Bellevue. Low transmission fluid can cause clunking if the fluid is old or low, preventing proper lubrication. A broken or loose transmission mount can also lead to clunking from movement. Issues with internal transmission components like springs, gears or bearings may cause clunking if any component's function is impaired. Owners experiencing clunking should take their car to a certified repair shop for accurate diagnosis and fixing of the problem.
