What happens if you overfill your transmission fluid?

What happens if you overfill your transmission fluid?

As we already learned, overfilling your transmission can increase fluid pressure and lead to the creation of foam. This undermines the lubricating properties of the fluid. The resulting transmission overheating can lead to a breakdown of the seals, causing the fluid to leak.

What’s the best way to drain transmission fluid?

Position the drain pan under the plug, remove the plug and lay it aside. Try not to allow the plug to fall in the pan. Be prepared for the fluid to come out immediately and position yourself to try to avoid fluid pouring down your arm. Allow the fluid to drain to a slow drip. Replace your plug, being sure to not over torque the nut.

What causes transmission fluid to leak from vent?

Leaking Fluid. Overfilling the transmission fluid will not cause seals to break, but they may leak. The transmission is vented so that pressure won’t build in the unpressurized areas. Transmission fluid can leak out these vents if it is too high. The seals higher in the transmission may also leak, but these seals are not pressurized.

Can a leaking transmission fluid cause a seal to break?

Leaking Fluid Overfilling the transmission fluid will not cause seals to break, but they may leak. The transmission is vented so that pressure won’t build in the unpressurized areas. Transmission fluid can leak out these vents if it is too high.

What happens if you put too much oil in the gearbox?

Too much fluid in the gearbox can also cause the oil itself to leak from the gearbox. The most critical thing about adding too much transmission fluid is that it causes a large pressure difference in the transmission itself.

Do you need to replace the transmission fluid?
