BMW ATF 6 Automatic Transmission Fluid (Part 832 223 555 99)

Maintain crisp gear changes and protect your BMW’s automatic gearbox with genuine ATF 6 transmission fluid (part 83 22 2 355 599). This factory-approved, fully synthetic oil is formulated to the precise viscosity and additive requirements of BMW’s six-speed automatic transmissions, delivering optimal shift quality, friction stability and component longevity.

Key Benefits

• OEM-Specified Formula
  Developed to BMW’s exact FLUID SPEC 81229402846 standards for direct compatibility with ZF 6-speed transmissions.

• Smooth, Consistent Shifting
  Low-viscosity base stocks and friction modifiers ensure rapid hydraulic response and precise clutch engagement across all temperatures.

• Enhanced Wear Protection
  Advanced anti-wear additives form a protective film on gears, bearings and pump components, preventing scuffing and extending transmission life.

• Thermal & Oxidation Stability
  Proprietary additives maintain fluid integrity under high operating temperatures, minimizing sludge formation and viscosity breakdown.

• Extended Drain Intervals
  Superior chemical stability allows longer service intervals while preserving peak hydraulic performance and corrosion protection.

Installation Overview

1. Warm Transmission: Run engine to reach normal transmission temperature for accurate fluid exchange.

2. Drain Fluid: Remove drain plug and drain old fluid completely into a suitable container.

3. Replace Filter & Seal: Install a new transmission filter and pan gasket or seal as per service manual.

4. Refill with ATF 6: Add fluid through the fill port or dipstick tube until the level reaches the specified mark at operating temperature.

5. Bleed & Check: Cycle through all shift ranges, then re-check fluid level and top up if necessary.

6. Inspect for Leaks: Verify there are no leaks and that shift quality is smooth before returning the vehicle to service.
