Abstract: A kit for improving the repair of a transmission. The kit presents components in a well organized fashion. The kit includes certain individual components and groups of components in preassembled subassemblies. For example, a subassembly can be preassembled to factory level tolerances. Thus, during the repair, the defective, subassembly can be removed and the preassembled replacement can be installed, saving a significant amount of repair time. It also makes the refurbished transmission less likely to fail. If the kit contains all of the transmission parts, then it is likely that all or only a portion of the parts will be used during the repair. Any unused parts can then be placed back into the kit, along with the used parts, and the kit can be returned for a partial refund or a credit.

Abstract: The present invention provides a universal power control module for automatic transmissions. The power control module includes a processor and at least two sensor inputs that convey engine and vehicle data to the processor. This data may include vehicle speed, engine temperature, throttle position, engine RPM, and other operational parameters. Both the type and number of data input to the processor may be changed to accommodate different engine and transmission combinations. At least two outputs convey commands from the processor to the transmission. Program circuitry defines the gear shift pattern of the transmission according to the engine and vehicle sensor data. This program circuitry can be programmed to define an optimal gear shift pattern for any combination of engine and transmission, independent of make and model.

Abstract: A method and apparatus for testing automobile transmission clutches are provided by the present invention. An operator assembles the clutch with the components on a fixture. The clutch has an internal spring assembly to be compressed and a circlip (retaining ring) to be installed to hold the spring under tension. The circlip is installed into a tool that is placed onto the clutch assembly and a press is used to push the circlip down over a cone in the installation tool, snapping the circlip closed in its final position. A different tool is then placed onto the clutch assembly that holds the clutch pack together. The press is again operated and the cylinder compresses the clutch pack. By applying air pressure to the clutch assembly through the fixture, the clutch pack is forced upwards to its closed position. The distance traveled by the clutch pack is visible on a linear gauge. This distance is the Clutch Clearance.
