Felpro now markets a stand-alone transmission controller for the 4L80E and
4L60E called the TCU.   The MOTEC systems are the only  aftermarket
controllers I know  of which can control these transmissions.  Art Carr, for
one, offers diesel transmission computers with reprogrammed shift

I don't know about the 4L60E, but the diesels with mechanical
injection and 4L80E had a trans controller.
There's a company that reprograms them to use with NA diesels, I can't
remember their name.  Any car or gas engine truck with the 4L60E
should have EFI, and trans control is in the same computer as EFI.
