I have the same TCM with a AXNA chip. The unit is out of an 93 van. And I also have the 4L80E trans and harness.
The transmission has a Goodwrench label on it, so that tells me that has been rebuilt. The transmission ID tag has a date code of 1995. Now the AXNA chip must be a custom chip for the updated rebuild. The VSS sensors are the black higher frequency type.
I plan on testing this in my 86 Monte Carlo in the future.
