FAQS on transmission gear oil

Q: What is the purpose of transmission gear oil?

A: Transmission gear oil lubricates gears and components to reduce friction and heat. It protects against wear and ensures smooth shifting in manual and automatic transmissions. Using the correct type maintains performance and longevity.

Q: How often should I replace manual transmission gear oil?

A: Manual transmission gear oil typically needs replacement every 30,000 to 60,000 miles. Always check your vehicle’s owner manual for specific intervals. Delayed changes can lead to gear grinding or failure.

Q: Can I use car gear oil for both manual and automatic transmissions?

A: No, manual and automatic transmissions require different oils. Manual transmissions use thicker gear oil, while automatics need fluid with specific friction modifiers. Using the wrong type can damage components.

Q: What happens if I use the wrong transmission gear oil?

A: Incorrect oil can cause poor shifting, overheating, or accelerated wear. Incompatible additives may damage seals or gears. Always verify viscosity and specifications in your vehicle’s manual.

Q: How do I check my car gear oil level?

A: Park on level ground, locate the transmission dipstick or fill plug, and inspect the oil’s color/level. Many manual transmissions lack a dipstick, so consult a mechanic if unsure. Low levels risk gear damage.
