As to the root of the question, why Isuzu is instructing Isuzu juice for your AW tranny, I can't say. I expect that any quality ATF would work,


I am afraid it is rather a special fluid. There is a service bulletin:

Isuzu currently offers two (2) types of Automatic Transmission Fluids these are specific to the transmission type. The new "Slip Control System" (SCS) Aisin transmission mated to the Direct Injection (DI) 3.5L engine requires a specialized "Slip Control System" (SCS) fluid. This fluid has been developed to work in conjunction with the new torque converter clutch material to provide a positive shift and reduce wear. The new Isuzu SCS Automatic Transmission Fluid needs to be used whenever a SCS Aisin transmission is serviced (see figure 1).
NOTE: The SCS Automatic Transmission Fluid is currently available through AIPDN in quarts (p/n 2-90531-200-0) and 5-gallon (p/n 2-90531-201-0) containers. Refer to parts bulletin no. AIPDN-PTS-SUV26-03 for additional information.
