QuestionHi Dick,
This may be stretching the modified abit but...
I have a 1977 Plymouth Volare Road Runner with a 340 backed by an aluminum 3 spd w/ overdrive manual transmission. The transmission is toast.I have been given an A-833 from an A body. Do you know if this is a direct swap and if not, will a slant six manual work. What else would be an easy swap. The motor is built fairly torquey with about 450 lb./ft. and 420 hp. Thank you in advance for any info you may have.......eddie
AnswerI found the following information on a web site - that's all I know about the A-833. My guess is that it would be a bolt in changeover. Just slither under there and measure the mounting bolt hole positions to make sure before you get too buried in the project.
It should be much more able to stand the torque of your engine than the overdrive unit you blew up!
For much better information about performance Mopars, I recommend the "MML" - an on line mailing list type of discussion group - those guys know what they are doing with modifications - I'm a totally original type guy, and I haven't paid any attention to their doings, but enough of them are also in our Imperial group that I've come to trust their competence.
What I found is following:
"In the early Sixties, Chrysler got together with New Process to create a new four-speed transmission to add to their full line of models. They asked New Process for a unit that was durable, as well as strong, and could be used in any of their engine configurations. The A-833 (or NP-440) became that transmission for Chrysler. Although it went through some changes over the years, it remained an important performance feature in Chrysler's passenger cars until 1979 and in the line of trucks and vans into the late Eighties. GM later adopted it for use in their truck line as well, lending to its proven track record of reliability. Its adaptability and performance make the A-833 a popular automatic-to-manual transmission conversion choice among muscle car fans.
The A-833 first appeared in all 1964 Mopar A-, B- and C-models (and the later E-models), and was offered in several four-speed configurations until the mid-1970s. It was reconfigured as an overdrive transmission, appearing in 1975 and newer model cars and trucks as a fuel economy feature. The fourth gear ratio was always 1:1; however, the overdrive version reduced the third gear ratio to .73:1 to be used as the overdrive, and fourth gear became third by reversing the 3-4-shift fork."

Have fun, and keep one eye in the mirror!
