What will my motor and tranny work in

You'll have to find one in good shape that has a blown motor , and you'll have to get it for dirt cheap ,, or sell it to someone that wants the headache of swapping motors .

Another Pontiac G6. So the cost of another car, plus the labor to swap the drivetrain and other parts over. Are you doing the work yourself? Labor costs will be expensive, and you will have a vehicle that you will spent more money on than it is worth. I'd take the insurance payout and just purchase another vehicle.

Or sell it as a parts car. Jim
