Abstract
This invention relates to the housing of a hybrid electro-mechanical transmission consisting of park pawl system located in the end cover portion of the transmission housing. The end cover portion is configured to cover the park pawl system and allow access to the components of the park pawl system for assembly or service even as the end cover portion remains attached to the main housing of the transmission. Beyond providing coverage to the park pawl system, the end cover portion also provides structural support to a main housing portion during operation of the transmission. A method of assembling a park pawl system between main and end cover portions of a transmission housing is also provided.
