Why is my transmission fluid coming out my vent tube?

If a pump can suck in air past a filter seal or anywhere between the filter and pump, this unwanted additional air intake will surpass the vents capability to exhaust it. The fluid will become aerated, rise up and blow out the vent and/or fill tube. Another cause is due to an over filled transmission.

Does the C4 transmission have a vent?

The C4 vent is on the top of the adapter housing, before the T-case. If you don’t have a body lift it will be difficult to get to unless your trans is already out.

Can transmission fluid leak from exhaust?

Another concern is automatic transmission fluid leaking onto the exhaust. Automatic transmission fluid can be more flammable than other fluids. For this reason, if you have an automatic transmission fluid leak that’s getting onto the exhaust, repair it sooner rather than later to help eliminate the possibility of fire.

Do automatic transmissions have a breather?

In conventional automatic transmissions, air flows into and out of the transmission housing through a vent or a breather tube during transmission operation. The in and out flow of air can be characterized as transmission breathing.

Do transmissions have an overflow?

You can’t overflow some gearboxes because of the way they have been designed. They have a system that will flow out or spill the extra oil.

Is there a vent on an automatic transmission?

In conventional automatic transmissions, air flows into and out of the transmission housing through a vent or a breather tube during transmission operation.

Why does a gearbox need a breather?

Breathers are an important function of any gearbox. They allow heat to escape and cooling air to enter the system, preventing unnecessary overheating issues.

Can a torque converter leak fluid?

Torque converter seals can get damaged for several reasons. But once they are damaged, you will experience fluid leaks. When you experience fluid leaks, you aren’t retaining the amount of transmission fluid; the torque converter needs to transfer the power from the engine to the transmission.

What are the signs of an overfilled transmission?
