Prokomon 3L Transmission Fluid Pump — Manual ATF Changer with Gauge & 8 Adapters, Clear Reservoir

If you service your vehicle at home or work on multiple makes, this Prokomon pump gives you a compact, all-in-one way to move transmission fluid without lifting the car or using a power drain. The unit pairs a 3‑liter reservoir with a hand pump, pressure gauge, pressure release cap, dispensing hose and a selection of eight adapters so you can connect cleanly to a wide range of transmission fill points.

How does the Prokomon pump make changing transmission fluid easier?

The pump simplifies fluid replacement by letting you transfer fluid directly into the transmission’s fill neck, eliminating messy funnels and guesswork. Its manual operation requires no power supply, and the pressure gauge helps you monitor flow so you don’t over-pressurize the system.

• 3L clear reservoir for visible fluid level and pre-measuring.
• Hand pump with ergonomic handle for controlled dispensing.
• Pressure gauge to keep flow under the recommended 20 PSI limit.
• Pressure release cap for safe depressurizing before disconnecting.

Which vehicles and situations is this transmission pump compatible with?

Prokomon includes eight adapters to fit common transmission fill ports across many passenger cars and light trucks. It works well for mid-maintenance top-ups, fluid swaps after a drain, or when changing fluid without access to a powered transfer pump.

• Adapters cover typical OEM fill neck sizes used on many market brands (see product images for specifics).
• Suitable for manual shop work and DIY driveway maintenance.
• Designed for automatic transmission fluid (ATF) and similar fluids; check your vehicle’s service manual before use.

What safety and performance features should I be aware of?

Safety is built into the pump with a pressure gauge and a release cap so you can manage fluid flow and avoid overpressure. The manufacturer advises not exceeding 20 PSI and recommends using an appropriate adapter and funneling technique to minimize spills.

• Gauge prevents accidental over-pressurization of the transmission inlet.
• Pressure release cap allows safe venting before disassembly.
• Use of the correct adapter ensures a secure, leak-minimizing connection.

How do I use the pump step-by-step for a clean fill?

Operating the Prokomon unit is straightforward: fill the reservoir, attach the proper adapter, insert into the transmission fill point, then pump until the system reaches the desired level. Drain old fluid first and confirm your vehicle’s fill procedure to avoid under- or overfilling.

• Open the reservoir cap and pour fluid in using a funnel to avoid spills.
• Tighten the cap, connect the dispensing hose and select the correct adapter.
• Insert adapter into the transmission fill opening after draining the old fluid, then pump to transfer fluid.

Who this is for: The Prokomon 3L Transmission Fluid Pump is aimed at DIY mechanics, independent shops and fleet technicians who need a portable, manual solution to transfer ATF without power tools. It’s useful when servicing vehicles that have difficult-to-reach fill ports or when a modest, controllable fluid volume is required. Always follow your vehicle manufacturer’s service instructions and use the right adapter and fluid type for the job.
