What causes a leak in the transmission pan?

The transmission pan is fairly easy to spot when you look at the bottom of your vehicle. Pan gaskets are designed to seal the pan so that it does not leak. If they do not have a perfect dry seal, transmission fluid can leak from this area. This can happen due to normal wear and tear.

How does a gasket on a transmission pan work?

Most gasket mounting requires a particular bolt torquing sequence. Depending on the style of transmission and the procedures set out by the manufacturer, the transmission pan mounting bolts have an order of how they should be tightened. This sequenced order of tightening the bolts allows the gasket to be evenly squeezed ensuring a proper seal.

Where does fluid leak in an automatic transmission?

The seals prevent fluid from leaking out between the transmission (also known as a transaxle) and the constant velocity (CV) axles. Automatic transmissions have lines that run to a dedicated cooler, which is usually located inside the radiator. These lines can develop leaks, often from the crimp area, leading to a pool of fluid under your car.

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 gasket be creased or flat?

These gaskets should be flat and never creased. If the packager folds them into a tight crease, the gasket may not seal the pan properly. 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.

What should I do if my transmission pan continues to leak?

Look closely with a flashlight to see if there are any cracks along the mating surface or pan where the leak continues and clean the area well to be sure it is the pan and not a leak from higher up coming down on the pan.
