Transmission Configuration

[Ken Kelly]

I also bit the bullet tonight and did a byte by byte, then bit by bit comparison
accross my 8 test bins. There are 4 Platform ID bytes per CPU. The second
platform ID byte on the T side has Bit 2 correlate with Transmission type
accross my 8 test bins. If anyone has other 94-95 LT1 bins, I'd like to test my
editor on them. I do need to know the GM code for the Bin or a description of
the car it came from.
