Hello, is 75000 miles to late to do Transmission Flush/Change for possibly first on 2007 Infiniti G35

I have a 2007 G35X, I bought it with 62,000 miles on it
I know some maintanence was done at dealership, however no record of transmission fluid change, I hear do it and I hear leave it alone.
Any suggestions?
I have replaced Catalytic Converter and pipes

all data says inspect fluid condition for burn't fluid and continue up to 125k miles. so if its good leave it if burn't rec service
The transmission is sealed and I have limited mechanic know how
The only way I can check is to take it to dealer,
could doing Flush/Fill cause any damage
IT HAS A CK AND FILL HOLE UNDER CAR.POSS YOUR MECH CAN CK THE CONDITION AND LEVEL FOR YOU,BUT YOUN NEEDD A LIFT
