In the 2009 Mercedes GL320 BlueTEC, common issues include transmission slipping and fluid leaks. It is recommended to replace the transmission fluid every 30,000 to 60,000 miles to prevent problems. Neglecting fluid changes can lead to noisy transmission operation, as old fluid can create unpleasant sound. A worn-out torque converter can also create headaches for drivers as the transmission is a vital component of the vehicle. Symptoms of transmission problems may manifest in the form of hard shifts, shudders, jerking, stuck gears, slipping, and delayed shifts causing acceleration issues. Promptly addressing any transmission fluid leaks is essential to avoid further complications.
