Purpose and Specifications

Valvoline ATF Pro 236.14 (item 866737) is a full synthetic automatic transmission fluid designed for Mercedes-Benz vehicles and other cars requiring MB 236.14 specification. This red-colored fluid keeps your transmission running smoothly by reducing friction, managing heat, and protecting internal components from wear.

The fluid meets ATF MB14 viscosity standards, meaning it flows properly at cold starts (around -20°C) while maintaining protection at normal operating temperatures (around 80-100°C). It comes in a convenient 1-liter bottle for easy topping up or complete fluid changes.

When to Use / Replace?

Recommended replacement interval: Every 5 years or as specified in your vehicle's maintenance schedule. Most modern automatic transmissions benefit from fluid changes every 60,000 to 100,000 kilometers, depending on driving conditions.

Use this fluid if your vehicle requires:

• Mercedes-Benz C-Class, E-Class, or Sprinter models (1991-2024)
• MB 236.14 or MB 236.12 specification
• ATF MB14 viscosity grade
• Full synthetic transmission protection

Signs you may need transmission fluid service: Delayed gear engagement, rough shifting, transmission slipping, or low fluid level on the dipstick.

Frequently Asked Questions

Q: Can I use this in any automatic transmission?
A: No. Always check your vehicle's owner manual or service documentation for the correct specification. Using the wrong fluid can damage your transmission. This product is specifically for vehicles requiring MB 236.14 or MB 236.12 standards.

Q: How long does an opened bottle last?
A: Once opened, use the fluid within the same service session. Transmission fluid absorbs moisture from air, which reduces its protective qualities. Store unopened bottles in a cool, dry place for up to 3 years.

Q: Is synthetic transmission fluid better than conventional?
A: Yes. Valvoline's full synthetic formula provides better protection at extreme temperatures, lasts longer between services, and reduces wear on transmission components compared to conventional fluids.
