The A999 transmission is commonly applied in XJ or YJ models with the engine capacity of 4 liters. The main difference between A999 and A904 consists in the rear band, which holds the planetary gear carrier: the band used in the 32RH transmission is more efficient. This gearbox is considered to be quite reliable, so it commonly outlives other stock components.
