How to Replace the Transmission Fluid for Mercedes-Benz GLC?
1 Answers
Mercedes-Benz GLC260L transmission fluid replacement methods are as follows: 1. Gravity Drain: The principle is similar to oil change. After loosening the tightening nut at the bottom of the oil pan, the transmission fluid will automatically flow out from the drain hole. Although this method is simple, it cannot completely drain the fluid. Some fluid remains due to mechanical structures like recesses and uneven surfaces. 2. Machine Flush: First, add new transmission fluid into the machine, then connect the machine's pipes to the transmission's fluid channels. Under hydraulic pressure, the new fluid pushes out the old fluid. This method cleans the fluid channels more thoroughly. The more new fluid used in the machine flush, the cleaner the old fluid will be removed. Machine flush typically uses about 10-15L of fluid. This method takes longer, usually around 1 hour. 3. Oil Pan Removal: This method replaces and cleans the fluid from the root and can also address dirty oil filters. Removing the oil pan is a major task, and labor costs are higher. Symptoms of deteriorated transmission fluid in Mercedes-Benz GLC260L: 1. Slipping: On slopes or other high-torque situations, insufficient lubrication causes gear slippage. 2. Leakage: Poor sealing of the transmission, possibly due to gaskets or seals. 3. Jerking: Deteriorated fluid and debris hinder smooth gear engagement. 4. Noise: Loud noises from the transmission during driving, indicating possible fluid deterioration. 5. Overheating: The dashboard may display a transmission overheating warning. 6. Stalling: Malfunction of components like the solenoid valve.
