The transmission fluid for a Mercedes-Benz GLE400 should be changed every 60,000 kilometers. Signs that indicate the need for a transmission fluid change include vehicle shaking, gear shifting hesitation, a transmission overheating warning on the dashboard, engine stalling, and unusual noises. The methods for changing the transmission fluid in a Mercedes-Benz GLE400 are as follows: 1. Loosen the drain screw at the bottom of the transmission to drain the old fluid and then refill with new fluid. 2. Remove the transmission oil pan directly to drain the old fluid and refill with new fluid: This method is more thorough than the first, as it removes impurities from the bottom of the oil pan. 3. Use a circulation machine to change the automatic transmission fluid: A smart circulation machine can perform dynamic fluid changes, filtering and cleaning sludge and impurities inside the automatic transmission. Different vehicle models have different change intervals. Below are the recommended change intervals for transmission fluid: Manual Transmission: Manual transmission fluid is generally recommended to be changed every three years or approximately every 100,000 kilometers. Automatic Transmission: Automatic transmission fluid is generally recommended to be changed every two years or approximately every 40,000 kilometers. Continuously Variable Transmission (CVT): CVT fluid is generally recommended to be changed every two years or approximately every 60,000 kilometers.
