Can i remove a 4l60e from a 93 cheyenne and install a 4l60 from a 92 cheyenne in its place? THE mount appears to be the same. I am unsure about back up trigger. 4l60 has 4 pin connector 4l60e has multi pin. is the back up ckt in 4 pin connector ? Will not using E connector cause any problems? Also installing the 92 4.3l . looking at the l60 shifting is mechanical and has mechanical cable activated passing kick down. l60e is still usable but don't have confidence in it and costly to rebuild. Any help would be greatly appreciated as this is in process over memorial day weekend.
