TRNW-2: 10R80 CDF air check tool

[Steve Everett]

      I have the sizers for the rings, but on occasion will leave the
factory ones in place if its a low mileage unit with no burnt clutches,
just did that yesterday on one with 90k miles,  clutches were like new,
valvebody was the issue with the unit.   the sizers I have are made by VMS
Concepts , they work great,
