WARNING: This page is about a different car, the 2008 Buick LaCrosse and 2008 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.

When shifted by D2 fluid, it allows D2 to enter the manual 2-1 servo feed passage to stroke the manual 2-1 servo assembly (104-115) and allows 3rd fluid to exhaust.
