    I'm not an expert on these swaps, but from what I've seen on the internet:

    '94 and older 4L60E's swap ok
    '95 is its own year
    '96+ 4L60E (OBS) swap ok

    I don't remember all of the specifics. One thing I've seen discussed is the TCC control. On the later model 4L60E, the control is pulse width modulated, the older models are simpler on/off type control.

    From what I've read, it's going to take more than just swapping that black box to get the '94 4L60E to work in your '96. Hopefully someone more knowledgeable in these swaps will chime in.
