I have a code p0700 and po599. Can the po599 be triggering the other code?

P0700 is transmission related. In theory, I suppose temperature could be related here. A P0700 is not a code that typically gets addressed on its own, but usually comes on as a result of other issues setting other codes. I would address the cause of your P0599 code first -- test and repair as needed -- then recheck.
