How much does it cost to get a transmission replaced? on 2000 Chevrolet Lumina

I turned a corner and the car slowed down and would not shift gears. I stopped and turned if off and since then it will not turn over. I was told it was probably the transmission. It has 165,000 miles and everything else is in great working condition.

You state that 'it will not turn over'. Does that mean that the engine will not start? If the engine won't run , how do we know what the trans is doing?
