Ojtrtdr 3L Transmission Fluid Transfer Pump Kit — 13 ATF Adapters, 40 PSI Gauge & 35" Hose

Ojtrtdr's 3L Transmission Fluid Transfer Pump is a portable, pneumatics-driven kit that quickly and safely transfers ATF and other automotive fluids using a pressure gauge, relief valve, 35-inch hose and 13 vehicle-specific adapters.

This compact pump kit converts compressed shop air into controlled fluid pressure so you can evacuate or refill transmissions, power steering, brakes and engine oil without crawling under the vehicle. Built from industrial-grade materials and rated for a 40 PSI maximum safe working pressure, the unit blends a rigid 3-liter reservoir with flexible tubing and a set of adapters to fit many late‑model cars, trucks and SUVs. It’s designed to speed routine maintenance, reduce spills and let DIYers or technicians manage fluid changes with more control than gravity bleeding or siphoning.

How does the pump make transmission service faster and cleaner?

The pump uses compressed air to pressurize a sealed 3L tank that forces fluid through the hose and into the transmission or collection container. The integrated pressure gauge and flow control let you dial in speed, and the 90-degree shut-off valve stops flow instantly to avoid messes.

• Pressurize with shop air for rapid transfer instead of manual siphoning.
• 90-degree shut-off valve allows precise start-stop control at the fitting.
• Pressure gauge shows real-time PSI so you avoid overpressurizing.
• Threaded relief valve for safe depressurization before disassembly.

Which vehicles and fluids are compatible with the kit?

The kit ships with 13 ATF adapters intended to match common transmission fill nipples and service ports across many cars, trucks and SUVs. The tubing and reservoir are suitable for ATF, engine oil, power steering fluid and brake fluid when used with correct adapters and precautions.

• 13 specialized adapters cover a wide range of manufacturer service fittings.
• Rigid bottle plus flexible nylon hose resists standard automotive fluids.
• Works for both draining and refilling operations where port access allows.
• Verify adapter fit and fluid compatibility before each use.

What safety features should I rely on during operation?

Safety is built into the design: a maximum 40 PSI rating, a manual pressure relief valve and a procedure that requires depressurizing before disconnecting any hose. Follow the two-step depressurization (open side relief valve, then remove adapter) to avoid sudden fluid or air release.

• 40 PSI maximum safe working pressure — do not exceed.
• Threaded pressure relief maintains stable pressure and prevents spikes.
• Always release pressure through the side relief valve first.
• Secure the pump cap with included wrench before pressurizing.

How easy is setup and everyday use for a DIYer or shop tech?

The manual pump is compact and portable, making it simple to carry around a bay or garage. Connect compressed air, choose the correct adapter, secure the cap and use the flow control and shut-off valve to manage transfer — most users can perform a service with minimal tools.

• 35-inch hose provides reach around engine bays and carts.
• Manual pump operation—no electricity required, just shop air.
• Included adapters reduce the need for extra fittings or specialty tools.
• Wrench included to tighten the cap and ensure a leak-free seal.

Who this is for: The Ojtrtdr 3L Transmission Fluid Transfer Pump kit is intended for home mechanics, mobile technicians and small auto shops that want a faster, cleaner way to service transmissions and other fluid systems. If you perform regular ATF changes, handle multiple vehicle makes or need a portable pressure-transfer solution, this kit offers a practical balance of safety features, adapter variety and portability. Always follow the included safety steps, confirm adapter compatibility, and never exceed the 40 PSI rating.
