INTRODUCTION ISUZU JR403-E “ELECTROMATIC”
The JR403-E transmission, also known as the “Electromatic” by GM, is currently found in 1988 and up GMC Tiltmaster Trucks, Isuzu Trucks, Nissan Diesel Trucks, Mazda Trucks and Mitsubishi Trucks. This fully electronic controlled transmission is similar in design to the RE4R01A found in Nissan Pathfinders, 240SX and 300SX vehicles, but on a much larger scale. This manual contains information and procedures for assembly/disassembly, diagnosing electrical problems, and was compiled from GMC and ISUZU factory repair manuals.
The JR403-E transmission is fully electronic controlled, consisting of shift solenoids, a line pressure solenoid, a converter clutch solenoid, a overrun clutch solenoid and a fluid temperature sensor. There is built into the vehicles a self diagnostic procedure to aid in diagnosing electrical concerns and is also included in this manual.
