This depends on the year of the truck - Pull out the transmission dip stick clean it and it will tell you. Dexron works for Isuzu NPR models up to early 2007.
But PLEASE NOTE that for late 2007 and up, NQR and NPR Imported Trucks come with a new type of automatic transmission that requires an inexpensive silicone-based Transmission Fluid. It is a must that you use a silicone-based fluid such as Isuzu SCS Automatic Transmission Fluid -- Isuzu part # 2-90531-200-0. If you don't use the proper fluid, it will burn up your transmission in a matter of a day. You cannot use regular automatic transmission fluid or a petroleum based fluid like Dexron in the NQR or NPR trucks built after late 2007.This fluid is not expensive at all, it costs about the same as Dexron.

The best way to confirm the type of transmission fluid to use in a 1989 Isuzu pick up is to refer to the owner manual. A retailer who sells the transmission fluid will be able to advise the correct purchase.
