Education needed......TH350 tranny versus 700r4 tranny

[1project2many]

my friend bought a 90s caprice with the LT1 in it and crashed the car shortly after he got it.

In the Caprice, the LT1 was only used with the electronically controlled version of this transmission, called a 4L60E. The older TBI engine was used with the 700R4. The electronic trans will have a large, green electrical connector on the passenger side while the older version will have a connection for a cable. This is a picture of an electronic transmission shamelessly stolen from another forum:

It's possible I'm confused about what vehicle the trans came out of then because he is 100% sure it's cable and not power but I'll verify when I pick it up. Thank you for the info!
