The transmission oil filler port of Changan CS35 is located in the engine compartment. Below are detailed introductions about the transmission oil filler port of Changan CS35: 1. The official user manual recommends changing the transmission oil every 50,000 kilometers or every three years. 2. The transmission mainly refers to the car's gearbox. It is divided into manual and automatic types. The manual transmission mainly consists of gears and shafts, achieving speed and torque changes through different gear combinations. The automatic transmission (AT) is composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations. 3. There are two oil ports on the transmission. The lowest one is the drain port, and the higher one is the filler port, which can only be seen when the car is lifted. Generally, unless the automatic transmission is overhauled, the oil inside cannot be completely extracted. Therefore, during replacement, usually only 70-80% can be replaced, requiring about 4 liters of oil. Transmission oils of different brands should not be mixed.
I remember when I last changed the transmission fluid for my Changan CS35 myself, I found that its filler port is usually located on the side of the transmission near the chassis, typically a labeled plastic or metal plug, positioned below the engine compartment. You'll need to lift the vehicle or use a pit, otherwise, you won't find it. For most CS35 models, it's near the drive shaft when viewed from underneath. Be careful to avoid dust entering the oil port during the operation, and it's recommended to buy professional transmission fluid and filling tools. I also noticed that if the fluid level is low, the car will shift poorly, and long-term neglect of fluid changes may lead to wear. The method to check the fluid level is to measure the cold and hot fluid with a ruler, just keep it level. Regular maintenance can save a lot of money, after all, the transmission is the heart of the car—don't skimp and add random fluids.
For DIY car enthusiasts, locating the transmission oil filler port on the Changan CS35 is actually quite simple: It's positioned on the upper side of the transmission housing, typically as a bolt-type plug. The exact location can vary—newer models might have it towards the rear of the engine bay, while older versions may place it closer to the bottom. I always keep a flashlight or phone light handy to peek underneath. Before starting, ensure the engine is off and cooled to avoid burns. Also, pay attention to oil compatibility—using OEM-approved ATF fluid is recommended. After refilling, check for leaks, as loosening the plug can sometimes cause issues. If you can't find it, consult the owner's manual or search for reference images online to avoid damaging wiring harnesses. Make it a habit to check every 50,000 kilometers to prevent transmission rust.
