Hello JACUSTOMER, it is common for the transmission to fail on this vehicle. There was a previous recall on this transmission to flush out the fluid as the fluid was not adequate for this vehicle. More than likely this transmission has failed and will need a complete rebuild. You need to ask the shop what rebuilding it will cost. It should be about $4000. The price you had was for a new transmission.
should I just donate the car or maybe sell to a junk dealer? Do I really want to spend $4000 on a car that is worth only 6000
First check to see what the shop will charge to rebuild it. See what they say is worst case scenario. Even at this price it is still cheaper to fix then to purchase another vehicle. That is assuming that everything else is in good shape and well taken care of.
