2000 CHEVROLET VAN Structurebodydoor Problems

I HAVE A 2000 CHEVY VENTURE VAN W/ ONLY 62043 MILES ON IT. WITH SOME OF MY KIDS IN THE CAR, THE ENGINE STARTED TO WHINE. BROUGHT IT TO A GARAGE, WHERE I WAS TOLD MY TRANSMISSION WAS JUNK AND IT WOULD COST ABOUT $2K TO FIX. I THANK GOD THAT I AT LEAST GOT TO A GARAGE AND THERE WAS NO ACCIDENT. THIS IS ON THE HEELS OF GASKET SEALS LEAKING IN THE ENGINE, ABS HUB CENTERS FAILING, ALL BRAKES HAVING HAD WORK (NOT JUST FRONT), SUSPENSION WORK, SLIDING DOORS COMING OFF TRACK. CALLED CHEVY DEALER WHO GAVE ME # FOR GM, WHO COULDN'T WORK OUT SOLUTION WITH ME BECAUSE I CHOSE TO SERVICE CAR AT LOCAL GARAGE AND NOT DEALER. NEVER MIND THAT THE DEALER WOULDN'T HAVE TAKEN MY EXTENDED WARRANTY. WILL NEVER BUY ANOTHER VAN FROM CHEVY AGAIN AND HOPE SOMEONE LEARNS FROM MY EXPERIENCE. *NM
