WARNING: This page is about a different car, the 2005 Buick LaCrosse and 2005 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.
    IMPORTANT: Follow this procedure exactly or the transaxle will have no reverse gear due to the servo pin missing the band.
  1. Jack up the driver side (channel plate side) of the car until it is higher than the differential side. This ensures that the reverse band is in the proper location and not cocked to the channel plate side of the case.
