55 views

No, ATF (Automatic Transmission Fluid) and 75W90 are not the same. ATF is specifically designed for automatic transmissions and provides lubrication, cooling, and hydraulic properties. 75W90 is a gear oil used for manual transmissions, transfer cases, and differentials, providing essential lubrication for high-pressure conditions. Always refer to your vehicle's manual to ensure you're using the proper fluid for each application.

FAQs & Answers

  1. What is ATF used for? ATF (Automatic Transmission Fluid) is used in automatic transmissions for lubrication, cooling, and hydraulic functions.
  2. Can I use ATF instead of 75W90 in manual transmissions? No, ATF is not suitable for manual transmissions; use 75W90 gear oil instead.
  3. What is the viscosity of 75W90 gear oil? 75W90 gear oil has a viscosity that allows it to perform optimally in high-pressure situations typically found in gearboxes.
  4. How do I check my vehicle's fluid levels? To check your vehicle's fluid levels, refer to the owner's manual for specific procedures related to ATF and gear oil.
