that's the "new" nomenclature name, 4l30e. the "old" gm nomenclature name is THM-R1. its a kind of boutique item, doubt you'd find that much drop in stuff for it. if it was installed in the isuzu rodeo/trooper, i can't imagine that it could be that weak, since those manner of trucks are expected to be able to pull at least 3000 lbs or so.
