I was doing searches on the best tranny and diff fluids to use and heard about a tool called a Mity-Vac, or a MityVac, that is used to pump the fluids vertically. I was wondering where I could purchase one of these, because I've heard that suction guns are absolute crap.

 

Go to Mityvac.com for a telephone number of the distributor nearest you. Harbor Frieght and brandsonsale.com both are retailers for the Mityvac line of vacuum and pressure tools.
