We have six 700R's behind big blocks and small blocks, one has been in service for 10 or 12 years. None of them have manual switches. One of the oldest ones is in a SS 454 El Camino that I have put over 40,000 miles on and my son in law has made countless passes down the 1/4 mile. I have one in my Longhorn behind a 454. I put it in drive when towing and it has towed a lot.

If it's going to see heavy use, I would install a trans cooler.
