These Aisin transmissions require a specialized "Slip Control System" (SCS) fluid. This fluid was developed to work in conjunction with new clutch pack material to provide a positive shift and to reduce wear. This new Isuzu SCS Automatic Transmission Fluid will need to be used whenever an Aisin transmission with the SCS feature is serviced.

After servicing the transmission, the fluid level MUST be set/adjusted correctly. Refer to the Service Manual for the proper automatic transmission fluid adjustment procedure.

Notice: If the transmission fluid level is overfilled or underfilled, it may damage the transmission.
