Transmission fluid provides lubrication, cooling, and the hydraulic pressure necessary for smooth gear shifting. However, a transmission fluid leak can quickly turn into a major headache if left unchecked, potentially leading to very expensive repairs. This makes it important to get to the shop at the first sign of a leak. At Kenny’s Transmission, we provide expert transmission fluid leak repair in the greater Indianapolis area. Here’s a look at five common sources of transmission fluid leaks.

Damaged Transmission Pan Gasket

The transmission pan is located underneath the transmission and holds the transmission fluid. As the miles add up, the gasket that seals the pan can degrade or become damaged, leading to leaks. 

Worn Transmission Seals

Your vehicle's transmission contains several seals to prevent fluid from leaking out. These seals can eventually wear out due to heat and friction, leading to leaks. Common seals prone to failure include the input shaft seal and output shaft seal.

Cracked Transmission Fluid Lines

Transmission fluid is circulated through a network of lines. These lines can develop cracks or holes due to corrosion, age, or physical damage from road debris. A leaky transmission fluid line can result in a gradual loss of fluid and may lead to transmission overheating or failure if not addressed promptly. 

Faulty Transmission Pan

In some cases, the transmission pan itself may develop cracks or corrosion, causing fluid to leak out. This is more common in older vehicles or those subjected to harsh driving conditions. A visual inspection of the transmission pan can reveal signs of damage such as rust or fluid residue. If the pan is compromised, it should be replaced to prevent further leakage.

Torque Converter Leak

The torque converter is a key component of the automatic transmission system, responsible for transferring power from the engine to the transmission. A leak in the torque converter seal can result in transmission fluid escaping.
