The overdrive transmissions that I was originally talking about were the 3 speeds with the planetary type overdrive unit controlled by an electric solinold. The type that Blackwater mentioned is interesting also. What little I have read has been about the Chrysler units. These are 4 speeds where 3rd is direct drive and 4th is an overdrive. One question I have about the OD 4 speeds that blackwater is talking about, is the cluster gear different than a regular Saginaw 4 speed? Thanks in advance, Jay
