Oil Pump 3L Dispenser | ATF Gearbox Fluid Filler | 8-Piece Adapter Set

This hand oil pump handles clean refills on sealed gearboxes and gear differentials. The 3L reservoir features clear liter markings and a built-in pressure gauge. It works as a manual transmission oil filler tool kit or connects to shop air to push heavy fluid through included adapters. Features and Benefits - Dual-mode manual pump and pneumatic port - Lets you pressurize by hand or hook up shop air to pump thick gear oil fast - Pressurized 3-liter fluid tank - Holds enough lubricant for full transmission service without stopping to refill - Integrated brass control valve - Starts and shuts off fluid output instantly to prevent overfilling pans - Set of vehicle-specific angled adapters - Threads directly into fill plugs on hard-to-reach sealed transmissions Applications - Refilling manual gearboxes and transfer cases with heavy 75W-90 gear lubricant - Pumping fresh automatic transmission fluid into sealed transmissions without an engine-bay dipstick - Performing differential fluid services on light trucks and passenger cars in home garages What It Is This 3L hand oil pump dispenser is designed for transferring transmission fluid and gearbox oil cleanly into vehicle systems. Built as a manual and pneumatic unit, it provides controlled fluid delivery without the mess of standard pouring jugs. The tool comes complete with an 8-piece adapter set to suit various vehicle fill ports. Its dedicated reservoir design helps keep fresh lubricants free from contamination during servicing. For mechanics working on modern drivetrains, it offers a contained, bench-ready method for refilling gearboxes, differentials, and automatic transmissions to their correct operational levels. Key Uses & Applications The primary use for this dispenser is servicing automatic transmission fluid (ATF) systems and manual gearboxes where direct access to the fill hole is restricted. - Dispensing gearbox oil and ATF using the 8-piece adapter set - Servicing sealed vehicle transmissions and drivetrain differentials - General fluid transfer across light commercial and passenger vehicles Workshops also look at general hand and siphon pumps to understand how to siphon gas with a hand pump or empty fuel tanks safely. While dedicated fuel transfer units require static grounding, this dispenser focuses on clean, high-viscosity oil servicing. How to Choose Selecting the right pump depends on fluid viscosity, capacity, and power source. A 3L manual and pneumatic dispenser suits routine gearbox servicing where controlled pressure is needed to push thicker oils into raised fill ports. If you primarily move low-viscosity liquids from drums, learning how to use a siphon pump or how to use siphon pump setups with standard gravity hoses may suit general fluid drainage better. For transmission work, ensure the reservoir volume covers your typical drain-and-refill capacity, and confirm the included adapters match your target vehicle fill plugs before starting the job.
