Hi! Thanks for the info. That's going to save me a lot of time. Thanks!4L60E was computer controlled, not the 700r4. The only electrical connection(s) on the 700r4 are for converter lockup and/or for the VSS for use with an electronic speedo. Connector for converter lockup is a square 4 pin on driver side. As designed, converter lockup was controlled by the ecm. Aftermarket has lockup kits so you can do away with the ecm. The first 700r4 I had was driven with no converter lockup at all with no problems.
