Pneumatic Transmission Fluid Extractor and Dispenser, 2.6-Gallon Air-Powered Tank with 15 ATF Adapters and Pressure Gauge

Servicing a modern transmission is where a lot of driveway jobs fall apart. Half of them deleted the dipstick, the fill plug sits somewhere you cannot get a funnel to, and a plain drain-and-fill leaves most of the old fluid trapped in the converter and cooler. This tank solves both ends of the job with one tool. Hook it to your shop air, flip it to vacuum, and it pulls the spent fluid straight up out of the case through the dipstick tube or fill port. Flip it back the other way and the same tank pressurizes and pushes clean fluid back in through the fill hole. No pump handle to work, no quart bottle balanced over your head, no fluid running down your arm.

The 2.6 gallon tank runs off compressed air with instant two-way switching between extract and dispense, a hands-free trigger lock so you are not standing there squeezing it, and built-in overpressure protection so it will not push past a safe pressure. Reinforced clear hoses and a pressure gauge let you watch the fluid move and read the tank pressure in real time, so you know it is actually pulling or filling and not just sitting there. The kit ships with 15 metal ATF refill adapters that thread into the common fill-plug sizes across most import and domestic transmissions, plus a quick-connect coupler on the fill hose, and it all packs into a case so the adapters do not scatter between jobs.

It handles more than transmission fluid too, engine oil, gear oil, and other automotive fluids all move through it the same way, so it earns a permanent spot in the bay for every fluid service you do. If you maintain sealed transmissions at all, this is the tool that turns a job you used to farm out into a clean afternoon on your own floor. Verify your fill-plug thread against the included adapters before you start.
