I am trying to find a DDC0196 Prom for an 3.32 ratio transmission or the MY8 option code. I found a car with the MY8 transmission but discovered the ECMU had a DDB0203 Prom. This raised the question of whether the chip had been swapped out or did GM actually switch to the DDB0203 chip in the Economy model. I certainly would like a PROM that matches the transmission.
