Ive always been told it can overpressurize the trans, which buils a lot of heat. THis can damage components in the trans if allowed to operate like this for a period of time.

It will "whip up" the fluid filling it with air bubbles, and fluid that is full of air bubbles does not lubricate your transmission well.

Suggested Repair

Do not keep driving with an overfilled transmission. Drain the excess fluid and restore the level to the specified mark so the fluid is not aerated, overpressurized, or overheated.

Conversation Summary

The owner asked what happens if a Ford transmission is overfilled and then driven. Replies said excess fluid can be whipped into air bubbles, reducing lubrication, and can raise pressure and heat enough to damage internal components if left that way.
