1996 was the last year for the C6 in an F250. Or, at least there are "calibrations" for a C6 in '96. In it's last years, the C6 might have been a rare, special order only item. I've heard that fleet operators (UHaul, FedEx, etc.) wanted it instead of the E4OD.
The C6 was available up to and including 1996, but was VERY strictly ordered. I've heard it wasn't available in California, and was only available in HEAVY duty applications.
