The transmission oil is supposed to be maintenance free and should never need to be filled (up to the scheduled replacement) unless there is a problem or leak.
Since the car is salvage though, who knows how much would be left in there or what might have happened to it. What kind of damage was done to the car? How many miles are on the car? I would consider getting the oil replaced at a GM dealer if the mileage is high enough.
In any case, the 6-speed manual transmission (F40 (MT2)) cars have a 3.1L fluid capacity dry.
