Prokomon Transmission Fluid Transfer Pump — 3L Reservoir, 13‑pc ATF Adapter Kit with Pressure Gauge and Manual Pump

The Prokomon 3‑liter fluid transfer pump is a hand‑operated transmission fluid changer that includes a pressure gauge, pressure release cap, dispensing hose and 13 ATF adapters for a clean, controlled refill.

This compact kit is designed to make checking, draining and refilling automatic transmission fluid simpler for DIY mechanics and professional technicians alike. Built around a 3‑liter reservoir and a manual pump handle, the unit lets you move fluid without tipping jugs or making messy pours. The included pressure gauge helps avoid overpressurizing the system, while the assortment of adapters covers many popular vehicle filler and dipstick tube sizes.

How do I use the Prokomon pump for a transmission fluid change?

Using the pump is straightforward: fill the reservoir, connect the correct adapter and pump fluid into the transmission through the fill port or dipstick tube. Start with the vehicle drained of old fluid, then transfer new fluid until the system reaches the required level.

• Open the filling cap and add fluid using a funnel to prevent spills.
• Select the adapter that matches your vehicle’s filler or dipstick tube.
• Tighten connections, monitor the pressure gauge, and keep pressure below 20 PSI.
• Use the pressure release cap to stop flow safely when finished.

What safety features help protect my transmission during transfer?

The pump includes a pressure gauge and a pressure release cap to control fluid flow and avoid forcing fluid into the system at unsafe pressures. Keeping the gauge below the recommended 20 PSI reduces risk of seal or component damage during topping or refills.

• Pressure gauge displays real‑time transfer pressure.
• Pressure release cap allows quick, controlled depressurization.
• Secure adapter connections reduce leaks and cross‑threading risk.
• Manual pumping offers tactile feedback versus uncontrolled power pumps.

Which vehicles and situations is this 13‑adapter kit suitable for?

The adapter set covers many common car, van and light truck filler configurations, making it a versatile choice for shops and home garages. It’s ideal for scheduled maintenance, partial fluid top‑offs, and post‑repair refills where precise control matters.

• Includes 13 different ATF adapters to fit various filler/dipstick sizes.
• Works with most popular passenger cars and light trucks — check adapter compatibility before use.
• Useful for shop use, mobile technicians and DIY maintenance.
• Compact 3 L reservoir simplifies storage and handling.

How do I maintain the pump for reliable performance?

Routine cleaning and correct storage keep seals and adapters serviceable for many jobs. After each use, flush the unit with a compatible cleaner or fresh fluid, drain completely, and store in a dry place to protect rubber parts and threads.

• Rinse hoses and reservoir after use to prevent contamination.
• Inspect O‑rings and adapters for wear before each job.
• Keep the pressure gauge free of impact and store upright to protect the gauge face.
• Replace components if threads strip or seals harden.

Who is this for: The Prokomon 3‑liter fluid transfer pump is aimed at car owners who prefer hands‑on vehicle maintenance, independent mechanics, and small service shops that need a portable, controlled way to transfer automatic transmission fluid. If you want to avoid pouring from bottles, reduce spills, and have a compact tool that fits many vehicle types, this pump provides a practical, budget‑friendly option.
