When I'm out shopping for one of these 700R4s; what am I looking for? What years and model cars are most likely? I get the impression from searches that I may want to look at late 80's A Body (Chevelle, Cutlas, Skylark)cars. Is that right?
I don't know if I want to do any major towing but it would be nice to know I could drag 3 tons 300 miles if I wanted to. Is that possible with a 235/700R4 combination?
I've read through a number of searches. They're plenty useful. I was looking for the ideas to be pulled together here and to hear any new ideas.
Thanks for your help.
If I did go with a 700R4, how would the torque converter lock be hooked up? Is it just a switch that I'd thow when at highway speeds? What if I forget to turn it off when I get off the highway, what damage am I going to do? You know I'll forget.

The most common source for TH700s is F-bodies (Camaros and Firebirds) and trucks. TH200-4Rs came in a whole buncha different platforms (G-bodies: Monte Carlo, Regal, Cutlass; B-bodies: Caprice, etc, Caddys and so on.) Btw, as I understand it, A bodies were discontinued (merged with G bodies) in 78.
You can do several things with the TCC locking. You can add a switch to lock it up. You won't forget too many time. It's just like forgetting to put the clutch in when you come to a stop. It'll remind you.
You can also get a kit to lock it based on vacuum, but the ones I've seen are sold by Painless and they're ridiculously priced.
My favorite solution is to make a wiring change inside the tranny so that it automatically locks up when it's in 4th gear. Here' a page on my site on how to do it:
