The 4L60E does not have a TV cable as the 700R4's do. The 'E' suffix indicates an electronically controlled trans. This means the transmission will not operate without either a OEM PCM or an aftermarket controller.

I have not heard of the 5L40E or the 6L45E either. A quick google search revealed that the 5L40E trans is rated at only 250 lbft, so it may not be suitable for use behind a small block.
