4 Common Causes of Transmission Fluid Leaks

Raptor Transmission • May 01, 2024

Transmission fluid provides cooling, lubrication, and fluid pressure. This makes it highly important that you’re driving with the right amount. When a transmission fluid leaks develops, it can lead to major problems. Such leaks should be addressed ASAP. At Raptor Transmission, we provide expert transmission fluid leak repair in the greater Houston area. Here’s a look at four common sources of transmission fluid leaks.


Damaged Pan Gasket

One of the most common sources of transmission fluid leaks is a damaged or worn-out pan gasket. The transmission pan is located underneath the vehicle and houses the transmission fluid. As the miles add up, the gasket that seals the pan can degrade due to exposure to heat and friction. This degradation can lead to leaks around the edges of the pan. Replacing the pan gasket is typically a straightforward task for the mechanic and can prevent further fluid loss.


Worn Seals

Another common culprit behind transmission fluid leaks is worn seals. The transmission system contains various seals that prevent fluid from escaping. These seals can eventually deteriorate, leading to leaks. Common areas for seal failure include the input and output shaft seals. 


Cracked Transmission Pan

The transmission pan itself can develop cracks or holes over time, leading to fluid leaks. This can occur due to corrosion or impact damage. Inspecting the transmission pan for signs of damage, such as visible cracks or fluid seepage, can help pinpoint the source of the leak. In most cases, replacing the damaged pan is necessary to resolve the issue.


Faulty Transmission Fluid Lines 

The transmission fluid lines that connect various components of the transmission system can also be a source of leaks. These lines can become damaged, leading to fluid seepage. Problems with fluid lines should always be repaired ASAP to prevent major damage from insufficient fluid.
