What type of oil is used in a manual transmission car's gearbox?
1 Answers
Manual transmission cars use 75W gear oil. Transmission oils are divided into two types: manual transmission oil and automatic transmission oil. Manual transmission oil is gear oil, while automatic transmission oil is also known as transmission fluid or driveline oil. The steps for changing transmission oil are: 1. Drain the old oil; 2. Remove the oil pan; 3. Install the drain plug and pour in new oil. The reasons for changing transmission oil are: 1. Over time, the viscosity of transmission oil becomes diluted, reducing its lubricating and sealing properties, increasing resistance, leading to greater wear and affecting the accuracy of the hydraulic system; 2. The oil deteriorates, reducing its anti-oxidation and cooling properties, causing excessively high oil temperatures and shortening the lifespan of transmission components.
