How to Replace the Automatic Transmission Fluid for Changan CS75?
2 Answers
Before replacing the transmission fluid, you need to drain the old fluid first. Loosen the drain plug screw at the bottom to release the fluid. The fluid exchange machine can simultaneously inject new fluid into the transmission and extract the mixed old and new fluid until the fluid inside the transmission becomes clear.
I previously changed the automatic transmission fluid for my Changan CS75 at home, and it felt quite simple to DIY. First, drive the car for a while to warm up the fluid to a moderate temperature, then turn off the engine and use a jack to lift the car. Place a pan under the oil pan to catch the old fluid, loosen the drain bolt to let the old fluid drain completely—this takes about 5 minutes. After draining, tighten the bolt back and slowly pour new fluid into the fill port. The CS75 requires about 4-5 liters of fluid, and it’s crucial to use the manufacturer-recommended ATF fluid type, such as Type 4 specification, otherwise, the transmission may develop issues. Wear gloves during the process to prevent burns or dirty hands. The whole procedure takes about half an hour, and I often do it myself—it saves money and gives peace of mind. I recommend changing it every 40,000 km to prevent transmission aging and sluggishness. Remember not to overfill or underfill; use the dipstick to check and ensure the level is correct.
