Is GM standing behind its faulty 6 speed automatic trans

I have a 2008 saturn vue xr that the trans just quit ,no warning or indication of problems
whatsoever . sounds like the wave disc problem so many people are having,( no reverse
and only first or second gear.Ive been told by the dealer it would cost $3 -$4 k. Hard to
believe for a 82,000 mile very well maintained vehicle. Totally disgusted ,you try to buy
American made products and first they close the car company then G M won't do a thing
for you! It's no wonder they lost a 100 million law suit over earlier saturns!! They don't
even call for servicing the trans until 100,000 miles,guess now I know why,it won't last
that long! Pretty pathetic!
