This unfortunate event not only leaves an unattractive stain in your driveway it also leads you to wonder- what is wrong with my car and how much is this going to cost me?

Auto Repairs Are EXPENSIVE


What is a Transmission Fluid?

When you think of the important parts of your car, transmission fluid is probably low on the list of what you deem as an essential piece of your car’s puzzle. In truth, transmission fluid is equivalent to the blood in our veins. Transmission fluid is vital to your car’s ability to run.


Transmission fluid lubricates all the moving parts in your transmission. With an automatic transmission, this lubricant also acts as a coolant. This syrupy thick fluid transmits power from the engine to the transmission. In manual transmissions (yes, people still drive manuals) a variety of fluids are used- in some cases, automatic transmission fluid is used, regular motor oil or heavyweight hypoid gear oil. Always check with your owner’s manual to confirm what you should be using on your specific car.


Transmission fluid should be changed every 60,000-100,000 miles for an automatic transmission but changing it more often won’t hurt. For a manual transmission, it is suggested to change the transmission fluid every 30,000-60,000 miles, if under heavy use it should be changed every 15,0000 miles.


How to Tell You Have a Transmission Fluid Leak- What are Transmission Fluid Leak Symptoms?

First and foremost you should identify if the annoying and unattractive leak in your driveway is in fact transmission fluid before you rush to any conclusions. Keep in mind that any leaking fluid from your car needs attention, but for the sake of this article, we will focus specifically on transmission fluid.


Leaked transmission fluid tends to be a reddish to brownish color, it will be slick to the touch and will have an oily smell. If you are unsure that it is transmission fluid leaking from your car, try placing a piece of clean cardboard under your car so that you can have a few fresh drops to determine if you are dealing with a transmission fluid leak. Next, identify where the leak is coming from. Leaked transmission fluid will be towards the front and center of your car. Other indicators that you may have transmission fluid leaking will be a car slow to start, if your transmission doesn’t start at all then you may have lost all of your transmission fluid.


What Causes Transmission Fluid to Leak?

Now that you have identified the symptoms of a transmission leak let’s identify what may have caused the leak in the first place. There are a number of reasons that can cause a transmission fluid leak, in fact, there are five main causes:


  1. A leak in the pan

The transmission pan is located at the bottom of your gearbox and it is vulnerable to fractures and punctures even though transmission pans are usually made from thick metal. Due to the location of the transmission pan, road debris can cause these cracks and holes that lead to leaks. Along with road debris, transmission pan damage can happen from hitting a deep pothole or running over a curb (it’s ok, we’ve all done this). If this kind of damage occurs, your transmission pan will have to be replaced.


  1. Broken seals

An automatic transmission has a large number of seals in order to maintain hydraulic pressure. Just like any other seal, these seals located in the transmission crack and degrade over time. When automatic transmission fluid becomes dirty due to lack of maintenance these seals can be exposed to an intense heat that can also cause these seals to crack and fail. This is why maintenance is so important for the health of your car, it can cause premature damage that is so easily avoidable. In the event that you have worn seals, it can lead to multiple areas for the transmission fluid to leak. Some of the seals that can cause the transmission fluid to leak are- sensor and plug seals, shifter housing seal, transmission pan gasket, speedometer input seal, tailhousing seal, etc.


  1. Fluid lines cracked

Made from either steel or aluminum, fluid lines of a transmission are used to move transmission fluid from the transmission pan to a cooling chamber that is located either inside or outside of the radiator. These transmission lines are normally very durable with proper maintenance and regular transmission fluid changes. When the transmission fluid lines are exposed to excessive heat or damaged from road debris these lines can crack or break entirely.


  1. Torque converter

The torque converter, which is located between the transmission and the engine flywheel propels transmission fluid into the entire system. The torque converter uses transmission fluid with a number of internal turbines to convert horsepower into hydraulic pressure. The hydraulic pressure is pivotal to operate the transmission. The torque converter is mainly made of metal, which is comprised of many internal bearings and turbine blades, all of which can wear out and create a transmission fluid leak.


  1. Transmission pan gasket

The gasket on the transmission pan is one of the most common areas to fail to cause a

transmission fluid leak. Whether due to improper installation, excessive heat

exposure, or just from old age this gasket failure can allow for transmission fluid to leak.

The cost of repairing a transmission fluid leak will vary drastically due to the year, make, model and what is causing the actual leak. The cost will also be affected by time, how long has fluid been leaking? The longer this problem goes without repairing the more damage it will cause, and in extreme cases, lack of attention will cause the transmission to burn out.

Is it Worth Fixing Your Transmission Fluid Leak?

Before you start wondering what you need to pawn or if you should sell an organ or two to be able to pay for your transmission fluid leak, let’s consider if your car is even worth such a costly repair. My guess is that if you have a leak you probably have other things that are failing on your car, especially if you are dealing with an older vehicle. As much as we want our mechanical best friends to last forever, that is unfortunately not always a possibility. Whether the car is failing due to lack of maintenance or you got your hands on one very sour lemon that has been bleeding you dry from day one, sometimes it’s best to part ways and move on to something more reliable.


Using reliable and trustworthy websites like Kelley Blue Book and Edmunds are great tools offered to the public to help determine the value of your vehicle. Keep in mind that these are rough estimates. These estimates are not written in stone. Once you have a rough idea of your car’s value this will help you decide how you want to move forward, maybe it is time to invest in a vehicle that will be a more reliable companion to you. Do you really want to lay in bed at night wondering what is going to fail on your car next?


Sell Your Car As-Is Even if You Have a Transmission Fluid Leak

Did you know that even a car that is non-operable is still valuable? To the right buyer, your car is a goldmine of useful and valuable parts. So who is the right buyer? Well, you have the traditional options of a junkyard or a dealership and thanks to the internet you have options like Craigslist. Each one of these options to sell your vehicle has its pros and cons, unfortunately, more times than not there are more cons than pros.


Remember the days of selling a car via a newspaper ad or the Pennysaver? For those of us old enough to remember it we also remember just how inconvenient of a process that was. Thankfully nowadays the process of selling a vehicle is much easier than it was just a decade ago. With resources like Craigslist, anyone can easily post a car for sale, but just like anyone can sell a car on Craigslist, anyone can contact you and at all times of the day. Craigslist has built itself quite the reputation and for all the wrong reasons. Consider Craigslist like a watering hole for scammers, user beware.


If you are now reconsidering using Craigslist and think that a dealership or junkyard is the safer route for you to down you would be right, but even though it is safer doesn’t mean you won’t be screwed in another way. Dealerships and junkyards are known for their salesman-like tactics. They will lure you in with an inflated estimate on your car just to undercut you at the last minute knowing that you are unlikely to back out. If your car is inoperable do you really want to pay to have it towed back to your house? Dealerships and junkyards know this and take advantage of you in the process. Their main goal is always what profit they can make, the last thing they care about is your best interest.
