Transmission leaks happen for a variety of reasons. Repairs can be as quick and simple as tightening the bolts on the pan, or as detailed as replacing an output seal. Here, drivers can learn some of the most common reasons for transmission-related Auto Maintenance.
Leaks
Many transmission fluid leaks occur due to a pan that comes loose when bolts aren’t fully tightened after the filter is changed. Sometimes, drain plugs may leak if they aren’t completely inserted after a transmission fluid flush or change. Both leaks are easy to repair, but they can cause expensive and severe damage if they are not immediately addressed.
Cracked and frayed pan gaskets may also leak. These repairs are relatively easy, and the parts typically cost $20 or less. Though it’s less common, the torque converter can also cause leaks. A transmission’s torque converter is a pump that creates hydraulic pressure and sends fluid through the entire system. In certain cases, a faulty needle bearing or a crack in the body can cause a torque converter leak that’s hard to diagnose and costly to repair.
Other Contributing Factors
A transmission is highly vulnerable to damage from flying rocks and road debris. If its bell housing is damaged, the immediate loss of fluid can incapacitate the vehicle. Fluid lines can be damaged by road debris; these lines are typically very durable, but a puncture or crack can result in leaks. The pan gasket’s surface can be warped, preventing it from sealing and allowing the escape of fluid. An Auto Maintenance professional will check surfaces for warping and other damage that prevents a proper seal.
Environmental Dangers of a Leaky Transmission
A transmission leak can cause serious problems for drivers and vehicles, but they are also a substantial concern for the environment. A fluid leak from a malfunctioning transmission is as poisonous as other petroleum products such as motor oil or gasoline. If left unattended, a transmission leak can cause severe damage to the ecosystem.
A transmission leak can be a frustrating occurrence, but thankfully most leaks are easy to fix
