What is the source of my transmission fluid leak?

Transmission fluid provides lubrication, cooling, rust prevention, and fluid pressure. This makes it very important that you’re driving with the right amount. So if you suspect that your vehicle is leaking transmission fluid, you’ll want to visit the shop ASAP so the source of the leak can be identified and addressed. Potential indications of a transmission fluid leak include red-to-pink colored fluid accumulating on the ground beneath your vehicle, as well as a concerningly low reading on the dipstick when you check your transmission fluid level. At SM Transmissions, we provide expert transmission fluid leak repair in the greater Grand Prairie, TX area. 


Common Locations of Transmission Fluid Leaks

Transmission fluid is known to leak from a variety of sources. Our local transmission mechanics are experts at pinpointing the location of leaks. One common leak source is that the transmission pan gasket has become degraded. The pan gasket creates the seal between the transmission pan and the bell housing. Regular wear and tear can cause this gasket to become worn down to the point that a leak forms. Transmission lines are another common source of fluid leaks. Transmission lines do the important job of transporting fluid between different transmission components. A leak can occur when there’s a crack in a transmission fluid line. The bell housing is another transmission part that sometimes cracks, causing the formation of a leak.


In your transmission, there is an assortment of seals and gaskets. When a seal’s rubber wears down, misalignment can result, which can then lead to a leak. Failing valves/solenoids may also be the source of a leak. For proper control over how transmission fluid is flowing, it’s important that valves/solenoids are in healthy condition.
