The JATCO JR710E is manufactured by the Japanese Automatic Transmission Company and has seven forward speeds plus reverse. Fifth gear is one to one, 6th and 7th gear are both overdrive ratios. We wish to thank ALTO USA for supplying us with the transmission that has made this presentation possible. This manual will cover theory of operation of the electronic and hydraulic control. It also covers passage identification of the case, valve body and spacer plate. This manual includes hydraulic circuit diagrams for all ranges and a Valve Body Mapping section which is a numbering system for passage Identification and oil flow.
