I've done a few Auto Trans removals and Installs.  The Negative Ground bracket makes a great plate to keep the Trans TC fully seated.

 

During removal:

- Remove the Negative Ground Lead

- When you have the trans moved back a 1/2" or so take the ground bracket and bolt it to the passenger side upper Trans/Engine Mount.  You can use the bolt that was there and one of the nuts from the lower studs

- The Ground Bracket 2" long or so will hold the TC in the trans

 

Install in reverse order

A great tip.

 

I bent up a little piece of metal to look like the factory tool, bolts to one of the starter bolt holes.

It took a weight off my mind, I can tell you.

I've never done this but I think I saw someone who used a combination wrench - they bolted through the socket end.

 

 

yeah - dunno if that would even work for our cars;
