Bruce:
the late trucks are $85, $0d, $31 and $0e
They are generaly lumped into standard or heavy duty. The HD are with 4l80E,
Std is 4L69E.

All of the PCM'S, (these are not ECM's, as they control the complete power
train). are very nearly identical and I thindk the software will interchange
with the exception of the Type $85.
