What is the model of manual transmission fluid?
1 Answers
Manual transmission fluid, commonly referred to as gear oil, comes in six models: GL-1, GL-2, GL-3, GL-4, GL-5, and GL-6. Among these, the heavier-duty models GL-1, GL-2, and GL-3 have been phased out in the market. Currently, GL-4 and GL-5 are more commonly used in household vehicles (GL-6 is typically used for buses). Methods to identify transmission fluid: 1. Smell the oil: Genuine oil has a burnt odor. 2. Observe the oil's flow: Genuine oil sticks to the bottle for a long time without clearing. 3. Check for bubbles: Genuine oil shows very few bubbles when shaken. 4. Assess the oil's viscosity: Genuine oil is sticky and hard to wipe off, forming threads when pulled.
