Posted on June 8-2011.
Owners of 2007-2009 Saturn Aura and Outlook, and 2008-2009 Saturn Vue equipped with the 6T70/75 6-speed automatic transmission may experience no reverse and slip/flare/harsh shifts in 3rd and/or 5th gear. Codes P0776 Clutch Pressure Control (PC) Solenoid 2 Stuck Off and P0842 Transmission Fluid Pressure (TFP) Switch 1 Circuit Low Voltage may be set.
The 35R clutch wave plate may be broken, allowing the piston to overstroke, causing the piston to leak and resulting in loss of apply on vehicles with greater than 25,000 miles.
During the repair process it is important to install the wave plate in the proper orientation to prevent the possibility for the failure to re-occur. Install the rounded edge of the new wave plate internal splines facing the 35R piston.
NOTE: The same TSB applies to 2007-2009 GMC Acadia, 2007-2009 Pontiac G5, 2008-2009 Pontiac Torrent, 2008-2009 Buick Enclave, 2008-2009 Chevrolet Equinox and Malibu, and 2009 Chevrolet Traverse, equipped with the 6T70/75 6-speed automatic transmission (RPO MH2, MH4, MH6 and MY9).

Glad to see the problem doesn't apply to the 2010 model year, hopefully they changed something in the tranny to fix it.
