ABSTRACT:
A tool set designed to facilitate the removal or installation of a clutch housing from the transmission case of a vehicle automatic transmission. The tool set consists of a first assembly and a second assembly. The first assembly is used to remove or replace the clutch housing from a GMC Turbo Hydramatic transmission series 325 or the like. This first assembly, consists of a tubular housing (20) that is inserted into a register on the front of the clutch housing. Once inserted, the housing (20) is tightened against the register by expanding the end of the housing with an expansion sleeve (26) located within the tubular housing (20). The sleeve (26) expands when it is pulled inwardly by the rotation of a compression means (48). The clutch housing is removed by applying pressure to a threaded shaft (50) that pushes against the transmission output shaft and release the clutch housing. The second assembly is used in combination with the first assembly to hold and center the output shaft at the rear of the transmission case during the removal of the clutch housing from a GMC series 200 transmission or the like. The second assembly consists of a body (56) having a recessed threaded hole in the middle and a plurality of legs (58) distending downwardly. Each leg has a headed screw (10) that allows the body (56) to be attached to the transmission case. A threaded shank screw (62) is located in the hole on the body (560). When rotated, the screw (62) contacts a dimple on the end of the shaft and holds the shaft securely in place.
