Followups set because you post to a.a.h and then dumped it for a
followup.

When you say ROM you mean PROM, right? One doesn't "flash" ROM, one
fabs it. As in a ROM is hard silicon with no programmable features.

It is quite possible that the fault lay not in the part but in the
instalation. Say a harness connection that wasn't 100% solid or some
such. Do you know for absolute fact that the replacement replacement
really was a "new" (likely rebuilt) tranny? It could also have been
an issue of a bad rebuild.

I stopped doing followup-to headers in this group with a short number of
groups at the request of another poster here - specifically the very
person I was replying to. Three groups that are pretty closely related
is not something one needs to worry about in that regard anyways IMHO.

The term ROM refers to EAPROMS, PROMS (that you erase with UV light) and
hardwired ROMS that can't be erased. PROMS can only be written to by
completely erasing them and re-writing the whole ROM. That's completely
different from RAM, where you can modify any byte or bit.
