OEMTOOLS 24937 Pneumatic Fluid Extractor 6L ATF Evacuator

A 6 liter (1.5 gallon) evacuator that pulls fluid out through a dipstick tube or fill hole instead of making you drop a pan or pull a drain plug. It runs two ways: hook it to shop air and the venturi head draws the tank down on its own, or work the hand pump if you are out at the vehicle with no air line. Same tank, same hoses, either method.

On the bench and in the bay this is the fast way to do a transmission drain-and-fill. Dipstick-tube units like the GM 700R4, 4L60E and 4L80E, the Ford AOD and 4R70W, and the Chrysler A604 all take the 41 inch dipstick adapter hose straight down the tube - drop the hose in, open the valve, and the pan comes up dry without a single bolt touched. On sealed late-model units that have no dipstick, the 5 foot suction hose goes in through the fill or check plug once the vehicle is level.

The other job it does every week is fluid sampling. Pull a few ounces before you quote a job and you can see what you are dealing with - clutch material suspended in the fluid, metal glitter off a failing pump or planetary, or that burnt-varnish smell that tells you the unit is already cooked. Cheaper than teardown and it takes two minutes.

An automatic shut-off valve closes suction when the tank fills, so you do not blow ATF back through the air line or spill it across the floor when a big-capacity unit gives up more fluid than you expected. Tank body is chemical-resistant and drains from the bottom into a waste jug. It also handles coolant, power steering fluid and brake fluid, and the small hose works for bleeding brakes.
