white trash, the tf999 was used in the wranglers until 96 when replaced by the aw4...however, they had been using the aw4's in cherokees since at least around 91... and the tf999 in the wrangler is a 3 spd coulumn shift, while the aw4 is a 3spd w/ overdrive, however the tf999 is an updated version of the tf727, in which many parts are interchangeable such as the clutches, and gear sets, and valvebody... all the tf 999 is a tf727 with different gear ratios, and updated asbestos free clutch materials
