Where are transmission oil leaks likely to come from?
One of the main causes of a transmission fluid leak is a gap in your transmission. This is hard to narrow down as it could be a space in a pan gasket, torque converter, fluid lines, the transmission pan, or the seals. It can be difficult to narrow down, so it is best to have a mechanic inspect your vehicle.
How can you tell if your transmission fluid is leaking?
Droplets of fluid underneath the transmission are a telltale sign of a leak. Automatic transmission fluid is typically red in color when it’s relatively fresh and clean. Manual transmission fluid (or gear oil) is semi-transparent or honey-colored. But what exactly causes a transmission fluid leak in the first place?
Is it possible to detect an oil leak?
Most oil leaks can be detected using the above methods, with a little bit of effort and detective work. However, some oil leaks can be very elusive, especially in high mileage vehicles where the engine may be very dirty and the oil leaks may not be so obvious.
Where is the leak in the transmission shaft?
That gasket can eventually wear out, resulting in a fluid leak. Output shaft seal leaks are a common problem. On vehicles that have a rear-wheel drive bias layout, the output shaft seal is at the rear of the transmission extension housing. The seal prevents fluid from leaking out between the transmission and the driveshaft.
Why is there no fluid in my transmission?
Transmission fluid is disappearing, no leaks evident. Not ever changing the fluid is usually what causes the transmission to fail; not changing it after the fact. If you’re losing fluid then it’s due to an external transmission leak, a faulty vacuum modulator, or a leaking transmission cooler.
How can I tell if my transmission fluid is leaking?
Automatic transmission fluid is still oil, but usually thinner than engine or gear oil and tinted red in color. If you’ve found that your car is leaking oil and it fits this description, then you most likely have a transmission leak. To check for a leak in your automatic transmission, you can do a visual inspection to try and find the leak point.

Can a new car have an oil leak?
Usually, oil leak problems are not a concern on new or fairly new car models, but as the engine accumulates miles, components age and deteriorate, making leaks a common maintenance problem from time to time. So, learning how to find them may prove a valuable skill.
What kind of oil is under the transmission?
Most of us know engine oil is brown or black, coolant is usually green, but you usually don’t see a red fluid. Automatic transmission fluid is still oil, but usually thinner than engine or gear oil and tinted red in color. If you’ve found this under your car, then you most likely have a transmission leak.
