Turbo 400 - Good, Bad, and Ugly
Is there a good, better, or best turbo 400 transmission for our trucks? Are there certain years with a better case? Should we be using a short 4", or a long 9" shaft transmission? Are there any benefits to one over the other? Can anyone recommend an upgrade kit for a junkyard transmission? Thanks.
