Aisin Transmission diagnostic troubleshooting for Mitsubishi Fuso trucks
Mitsubishi Trucks 1988 thru 1998 used the Jatco JR403E automatic 4 speed unit. 1999 and up used the Aisin 450-43LE transmission which is a 4 speed automatic. In 2004 they also started using the Aisin AS68RC transmission which is a six speed automatic transmission. Please be sure of what year your truck is and what model transmission you have as well after 2004 model years for proper diagnostics/troubleshooting ( Mitsubishi Trucks used both the four and six speed Aisin transmission after 2004).
