Mercedes-Benz ML500 reverse gear issue with delayed movement and difficulty reversing slowly on Mercedes-Benz ML500

Some Mercedes-Benz ML500 owners report experiencing issues with the reverse gear, including delayed movement and difficulty reversing slowly. A common concern is delayed gear engagement when shifting from "Park" to "Drive" or "Reverse," which may indicate a potential transmission system issue. Additionally, some owners find that a faulty brake switch can disrupt smooth gear changes in the automatic gearbox. Transmission fluid problems, such as improper levels, contamination, or a damaged filter, can also lead to difficulties in shifting gears, including in reverse. Furthermore, a malfunctioning Engine Control Unit (ECU) may cause trouble with both forward and reverse movement, often accompanied by a flashing Check Engine Light and decreased fuel efficiency. To resolve these issues, it is advisable for owners to have their vehicles inspected by a qualified specialist equipped with diagnostic tools to accurately identify the specific problem.
