I was looking around earlier and i found this

I also found a company that makes a lockup converter for the th400 as well. I mostly want to stay with the th400 because it's what originally came with the vette. if i do decide to go with the 700r4, how would i go about hooking it up to the vette's 3 speed shifter and hooking up the lockup converter?
