[Shop-talk] Oil plugs, WHY?

[John Mitchell]

I can definitely recommend the Mity Vac.  It's well made and just a few 
pumps pulls out any liquid you need to change, and just a flip of the 
swich and I pump it into a container to take to my city garage. Changing 
the transmission fluid on my truck can be a huge chore because you need 
to drop the exhaust to remove the pan cover.  With the Mity Vac, I suck 
out everything I can and replace it.  I know I can't get it all, so I do 
it every year to keep it nice and clean.
