10L Pneumatic Transmission Fluid Evacuator & Filler Kit

This is an air-powered fluid station that does both halves of a transmission service from one tank. Hook it to a shop compressor through the 1/4 NPT inlet and it pulls up to 170 psi of vacuum to draw the old ATF out through the dipstick tube or a cooler line, then a flip of the two-way rotary valve switches it to dispense mode at about 36 psi to push fresh fluid back in. That makes it the tool for sealed automatics that have no dipstick and have to be filled from the bottom under temperature.

The 10L (2.6 gallon) polyethylene reservoir is large enough to evacuate a full pan and a torque converter drain without stopping to empty it. A trigger lock holds it in continuous mode so you are not standing on the lever, and a spring safety valve pops off if the tank goes over pressure. The clear hoses let you watch the fluid move and judge how burnt the old oil is, and the panel gauge shows working pressure the whole time.

The kit ships with 15 aluminum ATF refill adapters that thread into the common fill ports and cooler fittings, three polyurethane and nylon hoses, work gloves, and a carry case. The 6061 aluminum adapters and PE tank shrug off hot, acidic used fluid, so it holds up as a daily flush tool rather than a one-job throwaway.
