Is Transmission Fluid Universal?
2 Answers
Transmission fluid is not universal and must match the specific requirements of the transmission. Transmission fluid is a lubricant that keeps the gear system clean and serves the following purposes: 1. Ensuring the normal operation of the transmission and extending the lifespan of the transmission components; 2. Providing effective lubrication even at low temperatures; 3. Reducing fluid loss under harsh operating conditions. Transmission fluids can be categorized into two types based on their structure: manual transmission fluid and automatic transmission fluid. Situations that require transmission fluid replacement include: 1. Reduced engine power; 2. Difficulty starting in low gears; 3. Gear shifting feels jerky or unresponsive, accompanied by unusual noises from the transmission; 4. Overheating of the transmission.
Transmission fluid is absolutely not universal. It's like wearing shoes - the wrong size will be uncomfortable, and the same goes for cars. In all my years of driving, I've seen that manual transmissions and automatic transmissions use completely different fluids. Automatic transmissions are further divided into AT, CVT, dual-clutch, etc., each requiring specific fluid types. If you use the wrong one, you'll experience jerky shifting, increased noise, or even total transmission failure. Repairs aren't cheap either, easily costing several thousand dollars. So never just buy any random bottle of fluid and pour it in. It's best to check your vehicle's manual for the recommended specification or have a professional shop select it for you. Regular fluid changes can also extend your transmission's lifespan and prevent bigger issues.
