FOUR UNCLES 6L Transmission Fluid Pump – Pneumatic Extractor & Dispenser with 15 ATF Adapters

Effortless Transmission Fluid Changes with a 6L Pneumatic Pump

FOUR UNCLES delivers a compact 6-liter (2.6 gallon) pneumatic transmission fluid pump designed to streamline extraction and dispensing. Powered by compressed air, the system helps you move fluid with less manual effort, freeing your hands for safer, more controlled operation. The unit features instant 2-way mode switching, a hands-free trigger lock, and built-in overpressure protection, all crafted to support smooth, repeatable fluid transfers during maintenance tasks.

Thoughtful design details support a clean, visible workflow. High-clarity reinforced hoses let you monitor flow as it happens, while a pressure gauge provides real-time feedback. A quick-connect filling hose ensures stable transfer and compatibility with transmissions that rely on dipstick access. The setup is complemented by a durable case that keeps adapters, hoses, and accessories organized for storage or transport.

Widely Compatible, Ready for Many Transmissions

Included are 15 metal ATF refill adapters, expanding compatibility across a broad range of vehicle transmissions. Each adapter is designed for a secure seal to reduce leaks, and the overall kit is compact enough for tidy storage in the included case. With dipstick-friendly fittings and flexible hoses, this system suits many engine bays and service environments.
