I picked my tranny up today, but they had it finished in in 24 hours. They didn't install my aftermarket TCC regulator valve but they specialize in rebuilds not modifications, so I put it in. I'm the modifier.

First pic is PML deep pan.
next is the valve bodies with these little balls that will fall out if you take the valvebody off with the tranny installed. the next one is the valve bodies before removal
The TCC valve has an easy to remove clip on the underside and it's roll pin is easy to lift if you compress the spring behind the TCC valve.
The difference in the regulator valves.
Then you have to restict the inlet orifice by peening the hole and retaping to .025"
I just peened it to a hairs width.
