Abstract
The present invention is a parking brake for a transmission or transaxle. The parking brake includes a parking block made of a material stronger than the housing and having keyways for engaging and locking the shift keys of the transmission. The parking block is located in recesses in the housing halves and is thereby prevented from rotating. By engaging the non-rotatable parking block, the shift keys are prevented from rotating and thereby prevent the rotation of the shift shaft and transmission of that motion to the axles.
