Nope, there was a differences course at one time between CL 60 and CL 65, but long gone. The G7500 is an amended GLEX TC, but a with a separate type course. Anyone with G6000 Fusion cockpit could pass a check in the 7500 in few sim sessions, sorry, five weeks on course in FAA. TC does have a short course for G7500 pilots with G6000 experience.
