Abstract
A solenoid unit includes a plurality of solenoid valves having respective valve bodies for attachment with a main casing of an automatic transmission and a case equipped with the solenoid valves in a manner that the solenoid valves can be installed in the main casing collectively. In the unit, the wiring for the solenoid valves has been completed in the casing prior to assembling the unit to the automatic transmission unit. With the arrangement mentioned above, if only attaching the solenoid unit to the main casing, it is possible to assemble the valve bodies of the solenoid valves to the main casing with a predetermined arrangement. Further, since the wiring for the solenoid valves has been already completed in the case, it is possible to omit the post-operation, such as soldering.
