Syphoned about 4 qts out of my 2005 Chevy 4L60E transmission. Worked well right out of the box. Has graduated lines to let you know how much oil/fluid you extract so you'll know how much fresh to put back in. Makes dropping the pan alot less messy. Just for grins and giggles I will use it the next time I change my engine oil. Mine was $50.00 shipped from the Liquivac site. Nice little tool.
