700R4 Case Air Check - No Test Plate!

I show you how to air check a 700R4 case without the use of a test plate. Air checking a completed case is an essential part of the rebuild QC process and your last opportunity to detect and fix any problems associated with applied element function. Test plates can be hard to find and/or expensive however they are not necessary if you have shop air, an air gun w/ a rubber tip and a small length of quarter inch vacuum hose.
