Transmission fluid

I've got 05 G35 Sedan with 116K miles. I recently dumped the trans pan and replaced the filter. I refilled with about 5 qts of the wrong fluid and drove it until I realized I used the wrong fluid.
I used Castrol Transmax CVT instead of Transmax import which is compatible with J/S matic.

I dumped the pan and refilled with transmax import. Should do another 5 qt flush or do I need to do the poor mans flush?

Do you think I did any damage to the trans? I did drive it after the initial refill but dumped it as soon as I realized my brain fart.
Thx
