Add the transmission oil through the filler hole located under the car's transmission. Below are specific details about transmission oil: 1. Definition of Transmission Oil: Transmission oil is a lubricant used to keep the gear system clean, ensuring the transmission operates properly and extending the lifespan of the transmission components. 2. Types of Transmission Oil: It is divided into automatic transmission oil and manual transmission oil. The former is specifically designed for automatic transmissions. The latter is generally referred to as gear oil, used for lubricating spur and bevel gears under normal loads, as well as gears in transmissions and steering systems.

Transmission fluid should be added through the transmission fill port, usually located in the front engine compartment near the side or top of the transmission housing, often marked with a colored cap for easy identification. Having worked on many cars myself, I know this job requires caution. If you're unfamiliar with the location, check the owner's manual first—it always provides clear markings. Manual transmissions typically have the fill port on the side, while automatics may have it on top. Use a funnel to pour carefully, avoiding overfilling; aim for the middle of the dipstick's full mark. Remember to regularly check the fluid level and color—if it's black or has a burnt smell, it's time for a change. For new cars, it's recommended to inspect every 40,000 kilometers or so. Adding fluid in the wrong spot can lead to leaks all over the engine bay, creating safety hazards, so beginners are better off seeking help from a professional shop.

I recently spent some time locating the transmission fluid filler hole when topping up my old family car: it's under the hood, along the transmission housing with a small capped opening, usually marked by a red knob. The procedure is quite straightforward, provided you understand your vehicle's layout; most cars are similar, though SUVs and sedans may differ in filler port height. I recommend performing this when the engine is cold for safety, and always clean around the filler cap before opening to prevent contamination. Fluid selection is crucial too - manual transmissions use GL-4 or GL-5 type oil, while automatics require the viscosity and brand specified in the manual. If you can't locate the port, don't force it; check online forums for your specific model where fellow enthusiasts often share diagrams. Regular fluid changes protect gear sets, extend transmission life, and save thousands in repair costs.

The transmission fluid filler point is usually located in the front half of the engine compartment. You need to lift the hood and look for the filler port on the side of the transmission itself—it's a small cap that can be unscrewed for refilling. I usually keep my car maintenance simple, but adding fluid to the wrong spot can be a real hassle. Once, I mistakenly poured it into the engine hole and ended up dirtying the machine. So remember: color coding is key—red or yellow knobs typically indicate the transmission fluid inlet. Use a dedicated funnel during the process to avoid spills, as cleaning up oily messes is tedious. Check the fluid level using the dipstick; pull it out to see the fluid height. Too low may cause part wear, while too high can affect gear shifting. If you're completely unsure about the location, bring the owner's manual to the garage and ask a mechanic—it saves time and is reliable. Generally, the filler hole is lower on compact cars, while larger vehicles may have it slightly higher for easier access.
