My transmission revs up and down while driving, could it be that the calipers on the front are not releasing causing the trans to be confused as to wether it should change or not.

There's no direct relation between the brake calipers and the transmission.
You can check for a dragging brake by feeling for a hot wheel after a drive with minimal brake use.
You don't give any info, like car model and transmission type, so I'm guessing 6-speed auto:
The rpm "hunting" could be an issue with the torque converter clutch.
If the trans fluid has more than 60k miles I suggest drain and refill with new.
Then cross fingers.

Thanxs for the info, I’ve a 12 Equss sig edition. I was told by a Hyundai tech that the cause of my transmission revving up and down while driving was because my calipers on the front were not releasing properly and causing the transmission to think that it’s still being slow down. I hope that makes sense.
