Post some photos. You might find a buyer for the entire car if it's not been beat to death.
What transmission is in it, the reliable four speed, or the junk five speed steptronic????
Either way they are GM sourced units and should not be too costly to rebuild. Call Level 10 and get a rebuild kit, throw a new converter in it if you can swing it and get back on the road.
As a parts car or non runnner it's likely not worth a whole lot, sorry.
