As manufacturers continually attempt to Increase the efficiency and driveability in their choices, we see different methods of achieving a certain aim. In the name of making vehicles easier to travel and minimizing emissions, the CVT gearbox has created a resurgence in recent times.
Action: This sort of noise commonly needs speedy focus from a professional mechanic. Driving that has a clunking transmission could cause further more injury and most likely bring on an entire transmission failure.
