I show and discuss the various differences between all 700R4 valve bodies that were produced from 1982 through end of production in 1993, some of which were driven by the introduction of the auxiliary valve bodies in late 1987.

I also cover the relevant changes to the separator plates, gasket sets and cases. Lastly, I provide details on part interchangeability across all years so that you know what can be swapped and what will not work depending upon what year of 700R4/4L60 you are working on.
