The type of transmission fluid you need depends primarily on your vehicle's make, model, year, and transmission type (automatic, manual, or CVT). Here is a detailed breakdown:

Key Factors to Determine Transmission Fluid Type

• Check your vehicle’s owner’s manual for the manufacturer’s recommended transmission fluid specification. This is the most reliable source

• Consider the transmission type: automatic, manual, or continuously variable transmission (CVT)

Types of Transmission Fluids

Automatic Transmission Fluid (ATF)

• Most common for vehicles with automatic transmissions.
• Common specifications include DEXRON (used by General Motors) and MERCON (used by Ford)

• Newer versions include DEXRON VI and MERCON LV for improved fuel economy and performance in modern transmissions

• Multi-vehicle synthetic ATFs are available and compatible with many makes and models, including GM, Ford, Toyota, Honda, Nissan, BMW, Mercedes, and more

• Synthetic ATFs provide better thermal stability, wear protection, and longer fluid life compared to conventional fluids

Manual Transmission Fluid

• Typically thicker and used in older manual transmissions.
• Not interchangeable with automatic transmission fluid.
• Some modern manual transmissions may use automatic transmission fluid instead

Continuously Variable Transmission (CVT) Fluid

• Specially formulated for CVT systems, which operate differently from traditional automatics.
• CVT fluids have unique friction modifiers and additives to protect the belt or chain mechanisms

How to Choose the Right Fluid

• Always use the fluid type and specification recommended by your vehicle manufacturer.
• For automatic transmissions, common fluids include:
  • DEXRON (GM)
  • MERCON (Ford)
  • ATF+4 (Chrysler)
• For CVTs, use a fluid specifically labeled for CVT use.
• Synthetic fluids are generally preferred for better performance and longevity, especially in severe driving conditions

Summary

• Identify your transmission type.
• Refer to your vehicle’s owner manual or manufacturer’s website for the exact fluid specification.
• Use the recommended fluid type (DEXRON, MERCON, CVT fluid, etc.).
• Consider synthetic fluids for enhanced protection and performance.
