This depends on the year of the Trooper and the engine in question. The 4 cylinder first generation Troopers that were offered with the auto ('88-'91) were equipped with an AISIN auto trans that has proven to be practically indestructible. All V6 Troopers were equipped with a GM 4L30E which has proven to be junk. I would have no concerns about buying a 4 cylinder automatic but absolutely, under no circumstances would EVER consider buying a V6 unless it has the 5 speed behind it. And just to go a step further I would avoid any Isuzu with the 3.2 or 3.5 due to the well documented engine and automatic transmission problems.
