Anyone with the ATC know how to adjust the actuators on the turret? When I open the solenoid the turret comes crashing down. It is empty, so I don't even want to try dropping it with tools in there.

Is it all-air, or air-over-oil? If the latter, is there oil?

It is all air.
There should be a small thumbscrew where the air line attaches to the cylinder that can be used to adjust the rate. You should be able to slow it down with these.

I can limit the lifting with the top thumbscrew, with in being air off. However, turning the lower thumbscrew in does not retard the rate at which the turret drops. My conclusions are that 1) the lower port needs to be replaced or 2) the hydraulic strut is bad. Don, what do you think?

Because of the effects of gravity and the weight of the platter assembly, we needed a large spring assist to the ATC assembly. It looks like what is on your car hatchback and serves the same purpose. Is yours connected on both ends?
I'm sorry I don't have any photos to help clarify.

Mac and Don we have replaced these a time or 2 on our machines as well. can possibly find a replacement at the auto parts store or truck bed cap installer. the exact replacement for ours came from a boat supply. I had a fun time convincing accounting it was for a milling machine and not my boat.
