Don't know anything about codes, but to the best of my knowledge you either have a cast iron cruisomatic or a C4 in your car.

Crawl underneath your car. The cruiso pan is wider than long. The C4 longer than wide. Cruiso has castiron case. C4 aluminum. Both have detachable aluminum bells and tails.

Dipstick on cruiso goes into pan - on C4 into case next to bell. C4 has two external servos - cruiso servos are internal.

Depending on application both can be good transmissions.
