BILITOOLS 4PCS Transmission Fill Tool

BILITOOLS 4PCS Transmission Fill Tool kit is a complete aluminum and zinc‑alloy service set designed to drain, refill and service Mercedes 9G‑Tronic transmissions and compatible Nissan/Infiniti models.

This compact kit bundles the specialized adapters and tools required to perform a professional transmission fluid service on vehicles equipped with the 9‑speed 9G‑Tronic gearbox. Built from corrosion‑resistant zinc alloy and lighter aluminum components, the set focuses on accurate fitment, reduced thread wear and reliable torque handling during routine maintenance. It comes in a dedicated case so technicians and DIYers can carry, organize and protect the adapters between jobs.

Which vehicles and transmissions will this BILITOOLS set work with?

The kit targets Mercedes‑Benz models fitted with the 9G‑Tronic (type 725.0xx) transmission family, including many C‑Class, E‑Class, S‑Class, GLC, GLE and GLS variants. It also covers certain Nissan and Infiniti models that share the 9G architecture in longitudinal front‑engine RWD/4WD layouts.

• Direct fit for Mercedes 9G‑Tronic units (OEM equivalents listed).
• Compatible with Nissan Z (RZ34), Frontier (D41), Titan and Infiniti QX80 in applicable configurations.
• Includes an M12 x 1.5 ATF fill adapter used on Mercedes‑Benz 722.9 derivatives.

How do these tools protect the transmission during service?

The kit mixes zinc alloy and aluminum parts to balance durability and gentleness. Zinc alloy adapters resist wear and deliver a secure seating; aluminum components reduce the chance of galling or stripping soft housings and threads during install and removal.

• Zinc alloy pieces for long‑term torque and repeated use.
• Aluminum components to minimize damage to transmission housings.
• Corrosion‑resistant finishes for reliable fit and lifespan.

What exactly is included and how do I use each piece?

The 4‑piece kit supplies the essential tools for a full drain and refill cycle plus screw removal/installation. Each component is sized for the common fill, drain and pan fasteners found on 9G‑Tronic gearboxes, and the set ships in a compact storage case for job‑site organization.

• 8mm oil pan spanner — remove/install pan fasteners quickly and cleanly.
• Fluid drain tool — controlled evacuation of old ATF to avoid spills.
• M12 x 1.5 ATF fill adapter — standard fill interface for many Mercedes units.
• Special 9G‑Tronic ATF fill adapter — tailored for the unique Mercedes fill port geometry.

Is this kit suitable for professional shops or home mechanics?

The BILITOOLS set is built to serve both independent shops and capable DIYers by providing shop‑grade construction in a portable package. It reduces the need to source individual adapters and helps ensure correct fitment, which saves time and reduces the risk of mistakes during a fluid change.

• Convenient case for mobile technicians and garage storage.
• Durable materials meet the demands of repeated professional use.
• Useful for DIYers who want correct, OEM‑equivalent adapter fitment.

Who is this for: Mechanics, fleet technicians and informed DIY vehicle owners who service Mercedes‑Benz models equipped with the 9G‑Tronic transmission — and those working on Nissan/Infiniti cars that use compatible 9‑speed gearboxes. If you need a single, compact kit that covers pan removal, controlled draining and correct ATF fill adaptors while protecting transmission threads, this BILITOOLS 4PCS Transmission Fill Tool kit is designed to make those tasks faster and safer.
