Yep, fan blades are there to keep the trans cool. A 75 day out isn't hot but the trans get hot from USE not from heat of day. Sure at 90 you need to worry more if a blade breaks off but overall you need to ensure the blades are there and working. I check mine after ever cut and blow the grass out underneath the seat. Overheating that trans is a bad idea and at the very least I'd fix the fan and replace filters (fluid drains out with filter removal) and refill with a good fluid like you mention. And pray you didn't damage anything internal. ZT4400's are gonna be an expensive fix if so. They are an extremely heavy duty transmission. (my Simplicity Citation XL has Zt3400's in it and my ZT-2500 has ZT2800's in it (less power).
