[Gmecm] 16197427 BNKM with 700R4

[Chris Reynolds]

With the 427 PCM simply check the TCC only option bit, along with the Automatic transmission option selected.  The code is all there, just needs to have the right option checksum checked.  It is very simple if you look through the hack.  It is at L400F, Bit 6, simply check the flag. Make for sure that L400F, Bit 7 is unchecked (Checked=Manual trans, Un-checked = Automatic Trans)

My '95 had a manual tranny and had a smaller prom than
yours. The chip was a 2732a and pattern was $9A. The
$0D is similar. Your prom chip is a 27C256 which is 8
times larger. Your cpu rom isn't compatible with a
$0D image. I would go with a new non-gm pattern which
runs totally out of the prom and disables the rom on
the cpu. The advantage with this is that the ALDL data
rates are higher and the data tables are larger giving
greater resolution. Have fun!!
