How to Know If the Transmission Fluid Is Enough?

Check the transmission fluid level directly through the transmission dipstick. Here are the related details: 1. Transmission Fluid: Transmission fluid is an oil product that keeps the gear system clean, ensuring the normal operation of the transmission and extending the life of the transmission device. 2. Applicability of Transmission Fluid: Most transmission fluids can be used in automatic transmissions on the market. In fact, each automatic transmission design has different technical requirements. Even the same model of transmission configured in different vehicle models will have differences in torque, weight, speed, structure, etc. Therefore, the original manufacturer has its own specified dedicated transmission fluid. Different transmission fluids are one of the factors affecting shift quality.
I've got over a decade of experience checking transmission fluid levels. The most reliable method is using the dipstick - after driving until the engine warms up, park on level ground with the engine running, pull out the dipstick, wipe it clean, reinsert it, then check the level. For new cars, the fluid should be slightly above the midpoint between the MIN and MAX marks, while older vehicles need a bit extra. If you notice delayed gear shifts (like obvious jerking when shifting from D to R) or lack of power during uphill climbs, it's likely low on fluid. Last year on the highway, I experienced this and immediately added half a liter at a repair shop - the difference was instant. Remember: automatics need fluid changes every 2 years or 40,000 km, manuals can last longer, but never wait until the transmission starts making grinding noises.
Checking transmission oil requires proper techniques, and I personally supervise it during every maintenance. The key is to distinguish between cold and hot engine conditions: oil level readings are inaccurately high when cold, so it must be checked at idle after warming up. Lift the hood to locate the dipstick marked AT or MT - the ideal fluid level is in the middle of the crosshatched area. If you notice the oil has turned black or emits a burnt smell, it needs replacement even if the quantity seems sufficient. I learned this the hard way when low oil caused transmission overheating last time, making gear shifts feel like being kicked. Now I've developed a habit of casually pulling out the dipstick for a monthly check, while also inspecting the undercarriage for any leaks. Actually, many vehicles start losing oil after 50,000 kilometers, especially those frequently stuck in traffic.
