Best years for your swap are from a 1987-92 Chevy pickup 700R4, these had all the factory upgrades and are non-computer unlike the later 4L60,avoid the earlier years as they had a lot of bugs.Also it is critical to properly adjust the T.V. cable,improper adjustment can toast one in minutes,google"700R4 T.V.cable adjustment" for how to info.

TCI makes a constant pressure valve body that eliminates the need for the critical TV cable adjustment.The TV cable is used just as a kickdown cable only.
