What causes a leak in the transmission pan?
Here are 5 of the most common causes of transmission fluid leaks. Over time, your transmission pan will eventually experience some wear and tear. This is because while driving, the pan of your transmission is susceptible to damage from all the loose rocks and debris on the road.
What causes an oil leak in the oil pan?
There are some common causes for a leak from the oil pan: one would be a worn-out gasket and another might be impact damage. A third reason the oil pan can leak would be that the oil drain plug and/or its threads are compromised. Oil sits in a reservoir called the oil pan, which is bolted to the bottom of the engine block.
Can a low oil level cause an oil leak?
A low oil level can also indicate a leak—potentially from the oil pan. Engines can leak oil from many locations, plus they can also burn oil. As such, you’ll need to do some homework before condemning the oil pan and/or gasket. Smoke coming from under the hood is always a bad thing.
Do you need to replace the oil pan gasket?
Typically, to fix a leak from the oil pan area, you’ll need to replace the oil pan or gasket. Usually the oil pan won’t need replacing unless it’s damaged externally or has oil drain plug threads that have been destroyed – this happens on aluminum oil pans over time more than on the stamped steel oil pans.

What causes oil to leak out of the oil pan?
The oil pan gasket has only one important job to do and that is; sealing the oil pan to the bottom of the engine. But, it is not uncommon for the gasket to wear out and start leaking oil. As a result, when a gasket is damaged; oil will leak out past the gasket and on to the ground.
How does the dry gasket seal the transmission pan?
The dry gasket forms a seal against the transmission case, when we tighten the bolts to specifications. When manufacturers use RTV to seal the transmission pan, they are careful to apply the correct amount. Many types of RTV are available and using the proper type is important.
What happens when you turn off the oil pan gasket?
This turns out to be a good thing, if you have an oil pan gasket leak. So, once you turn your vehicle off the oil settles below the gasket, and the leak will stop. This also can make it difficult to identify an oil pan gasket leak. Because, the only time oil is leaking from the oil pan is, while you are driving.
What should the transmission pan gaskets look like?
Quality vendors package their transmission-pan gaskets to remain flat. As with the other types, we first clean the pan and transmission and install the gaskets with no sealer. Over tightening the bolts can easily damage the pan of a transmission. The flange of the transmission pan should be flat and have no bulges.
Do you need to remove the transmission pan?
This is good maintenance and lowers our risk of transmission problems. Proper transmission service requires us to remove the pan on those transmissions that have them. After the service, we need to reseal the transmission, and this is when problems often begin.
What should I do if I have a transmission leak?
This is a transmission leak and a common cause is the transmission pan. Tightening the pan bolts is the most common advice given. This is usually wrong and can make things much worse. We should always tighten transmission pan bolts to the specified torque, when we install them. This is done with a torque wrench.
Can a transmission pan gasket leak during installation?
Following the information provided below during your new transmission pan gasket installation should ensure that you do not experience a premature transmission pan gasket leak.
Is it possible for a transmission pan to come loose?
Pan gaskets do not shrink and pan bolts rarely come loose. This is why we see very few transmission pans leaking on vehicles that someone has not serviced. Over tightening the pan bolts will only damage the gasket or worse, strip the bolt threads. Manufacturers use several methods to seal the pan on their transmissions.
Why do I have fluid under my transmission pan?
A few days after replacing the transmission pan, we may find spots of fluid under the vehicle. This is a transmission leak and a common cause is the transmission pan. Tightening the pan bolts is the most common advice given.

When do you know you have a transmission leak?
If you notice some read fluid leaking from your vehicle, it’s a sure sign that you have a transmission fluid leak. You should address transmission fluid leaks quickly to protect it and prevent even more costly repairs at best, or transmission replacement at worst.
What causes a transmission pump to leak fluid?
Otherwise, more serious problems will soon follow. Transmission fluid is propelled into the whole system by the torque converter. If this torque pump has a crack anywhere on its body or has damaged needle bearings, it will leak transmission fluid.
What causes a transmission fluid line to crack?
#5 – Fluid Line is Cracked. The fluid lines of a transmission are constructed of either steel or aluminum. These lines are usually quite durable but if they get damaged from road debris or exposed to heat too often, then the lines can crack or even completely break.
What happens if you let transmission fluid leak?
If you let too much transmission fluid leak, the transmission will begin to slip, which can quickly cause long term damage. Unlike oil, transmission fluid is flammable, and will flash if it hits the exhaust manifold. If it is leaking there (usually out the dipstick) it should be dealt with immediately.
What causes transmission fluid to leak from Honda Civic?
If your Civic is slowly leaking transmission fluid from the pan directly onto the ground, the transmission leak is as serious as when it leaks onto the exhaust. You should still deal with it right away. Here are some of the most common places that your Honda Civic may leak transmission fluid from. 1. Transmission Pan/Gasket
What causes an oil pan to leak in a car?
Oil sits in a reservoir called the oil pan, which is bolted to the bottom of the engine block. The pan itself may leak if it sustains impact damage from an accident or road debris. This is far more likely if the oil pan is cast aluminum than if the oil pan is stamped steel.
