When should the transmission fluid be changed for an automatic transmission car?
2 Answers
Automatic transmission fluid should be changed every 60,000 to 80,000 kilometers. Expired or deteriorated transmission fluid can cause difficulty in shifting gears and wear on transmission bearings. Transmission fluid is crucial for automatic transmissions as it serves to lubricate, dissipate heat, and transmit power within the automatic transmission. The method for changing transmission fluid is as follows: 1. Start the engine to warm it up, allowing the transmission to reach operating temperature. Remove the drain bolt and collect the old fluid from the transmission; 2. Once the hot fluid has completely drained, open the oil pan and replace the filter. Reinstall the oil pan and tighten the drain plug; 3. Add new transmission fluid, start the car, and shift through all gears; 4. Check the automatic transmission fluid level to ensure it is normal and make adjustments as necessary.
Every time my friends ask me about this, I always share some experience. Having driven automatic transmission cars for over a decade, I've found that transmission fluid is as crucial as drinking water for us. If not replenished and replaced in time, the engine will cry out for thirst. The manual suggests changing it generally every 40,000 to 60,000 kilometers or every two years, but I believe it depends on how you use your car. For instance, if you're stuck in city traffic every day or frequently haul luggage on highways, the fluid depletes faster, necessitating a change every 30,000 kilometers. Neglecting this can lead to the fluid turning black with a burnt smell, causing the transmission to stick or slip, and you'll feel strong jerks during gear shifts. I once overlooked it, resulting in heavy sludge buildup that cost me thousands to repair. Since then, I've made it a habit to check the fluid level and color during every maintenance, ensuring it stays a fresh, clear red for peace of mind. A long-lasting car relies on the accumulation of these small attentions—don't wait until it breaks down to regret.
