Carrier/rack problems of the 2005 Saturn VUE

I bought my 2005 Saturn Vue in December 2013 and have had nothing but problems since. When I first bought it I noticed a problem with the brakes. They have always worked poorly. I replaced the pads, then both front calipers 3 times. Then finally the hoses which helped somewhat. I recently had to replace the carrier bearing which helped the shaking and clunking I have read about in other posts. Just last month though right after I had spent the money on the carrier bearing I attempted to leave my driveway and when I tried to shift it hesitated then once it did start moving there is a loud grinding sound and jerking. My transmission now needs replaced. I have researched recalls and have found none that will help me with this. I regret ever buying this Vue and now I still owe 2000 to the bank for a vehicle I cannot afford to fix.
