By overfilling the transmission, the lubrication level isn’t the same, leading to much faster wear. As the transmission continues being exposed to high pressure, you will start to notice issues with shifting and functionality. It could even lead to the next issue, complete failure.

Is it OK to slightly overfill transmission fluid?
If it’s only slightly over, say less then a pint, it will be fine. Most auto makers know this is going to happen, so there is a margin for error. If it’s any more than that, I’d recommend draining some out or it may not function properly and could cause damage.
