Yes, definitely meant 700R4. We have been messing with them since they first came out and for the first couple years were kind of fragile except for the Corvette. I believe the 86-93 were the ones with the four pin plug and were the most sought after. I remember we used to use a Chrysler oil pressure switch and also a Suburban dual brake light switch for converter lock up before the harnesses were offered but that memory has long since faded away. Now all all the crate engines we use are the LS series and come with some 4L60's but mostly 4L80's and harnesses so it's mostly just plug and play anymore.
