Abstract
The electronic-hydraulic transmission control module has a hydraulic plate, an electronic control unit, and a sensor. The sensor is caulked into a wall of an opening in the hydraulic plate forming a plastic deformation.
Claims8
A method of manufacturing an electronic-hydraulic transmission control module, which comprises the following method steps:
- providing an hydraulic plate formed with an opening having a given width and a sensor having a larger width than the given width of the opening;
- caulking the sensor with the larger width in the opening;
- mounting an electronic control unit on the hydraulic plate;
- and
- producing an electrical connection between the sensor and the electronic control unit.
