If the car was on a flatbed the number of miles it went does not matter. I can't believe anyone operating a flatbed tow truck would pull a Corvette up on the flatbed in park unless it was an emergency and they could not put it in neutral. You need to explain better what happened. Dan

I am sorry if there was a miss understanding. the car was in neutral when he winched it up on too the bed then after the tow I got into the car on the bed to steer it down that's when I noticed the car was in park the entire tow distance strapped the wheels down and towed the car in park when we winched the car back down
in neutral put it back in park now turn the car over Hurd a big clunk eng is seized it seems something is jammed won't turn over now put socket on crank bolt won't budge was trying to figure out what may have damaged the eng trans. I haven't raised the car yet too take a look any idea would help

I have experience on both sides of the isle, I spent many years as a Corvette mechanic and several years driving a tow truck and I see no reason the tow has anything to do with a locked up motor
For some reason the car wound up on the truck, so what could make a Claimed to be a free spinning motor be locked up in transit nothing, except something that has Nothing to do with the tow Fluid Lock/Hydraulic lock wheath a water jacket or dumped fuel something could be doing it.
So pull the plugs and try,
Truthfully the truck is not to blame

It seems pretty normal to me. Winch the car up in neutral and put in park for the travel and put back in neutral for lowering back down. I don't think anyone here will be able to tell how your engine seized up from the info you have given. Might want to talk more about why it needed to be towed. Dan

I totally agree I have been thinking what ifs the only thing I can think of is a manifold full of fluid and when tilted on the ramp back cylinders filled.
Not trucks fault

Your car is probably hydro-locked. Either coolant or gas. Do not try to start it. Pull the spark plugs and try to turn by hand. Report back what comes out of what cylinder. If you don't know how to do this your other option is have it towed again to a mechanic who does. Dan

I had some trouble understanding what was being said. I took his statement, "driver strapped my wheels down and left car in park" as saying he pulled it up in park. But, you are correct he never said it was pulled up in park. Thanks, Dan
