No problem, I just want to know if it's wise to go ahead and change fluid and go to synthetic.

Good morning,
Synthetic is not standard for this transmission.
If you were to want to replace it, it will be difficult. The torque converter contains six quarts that cannot be drained unless it is removed.

I would just use the recommended fluid and stick to that.
