TRNW-2: 6r140 valve body and sonnax tooling

[pat schulte]

I know on the 10Rs, I have gone the way of Zipkits vs a Ford VB. It has
been pretty successful, I think I have only had 1 or 2 that the Zipkit
didn't fix issues but a new VB did. I have only done a handful of 6R140s so
I cant speak to them. I usually did install a new VB on them.
