Chrysler described the change as “an A-833 four-speed transmission, converted over to a three speed manual transmission with an overdrive gear ratio.” It was used with both the
318 V8 and
225 slant six. After the 1975 run, Chrysler switched to a finer-pitched gear tooth design to reduce the noise of the 1975 models, and changed the overdrive from 0.73:1 to 0.71:1. It used a steel housing except on the Feather Duster and Dart Lite, where it had an aluminum case and extension housing.
