You hear odd noises coming from the transmission: Your transmission may have difficulty shifting between gears, or there may be clunking or grinding noises during shifts. This can indicate transmission fluid loss, high internal transmission temperatures, or both, which can be caused by a bad transmission cooler.

Are transmission coolers necessary?
A transmission cooler helps the transmission stay cool, even when working harder than normal, which in turn lets you get the best performance and long life out of it.
Do transmission coolers make a difference?
A transmission cooler will just help to prolong the life of the transmission by keeping the fluid cooler. Transmission fluid cannot be cooled too much, so the addition of a cooler is a good idea, especially if you are towing.
How much does it cost to install a transmission cooler?
You can have a local transmission shop install a transmission oil cooler in your vehicle. Expect to pay between $150 and $250 for the job. Either way, installing an auxiliary transmission oil cooler is one of the best investments you can make in protecting your transmission from overheating and certain failure.
What happens when a transmission cooler goes out?
When a transmission oil cooler hose fails it can cause the transmission to overheat. This can be due to low fluid level from a leak or preventing flow. In either case if the transmission overheats it can stop working entirely and this condition may be permanent.
What are the common symptoms of failing oil cooler?
- Oil Leak. When the oil cooler gasket fails, it is unable to keep oil in.
- Overheating Engine.
- Contaminated Oil.
- Decreased Engine Performance.
- Black Smoke.
- Vibrations.
- Expanded Radiator.
- Engine Temperature Changes.
Should a transmission cooler be installed by a mechanic?
The installation and kit If you are going to get a cooler installed, make sure it’s done by a transmission specialist. We contacted several diesel mechanics who had not done these installations; some automotive transmission businesses suggested they could do it but had not had much experience with these units.
Which type of transmission cooler is best?
Stacked Plate They use a tube to carry the ATF inside the cooler itself, while the fins are used as a passageway for the ATF as it travels through the cooler. The stacked plate is the most efficient of coolers, the most popular, and the easiest to install and remove.
Does coolant run through transmission cooler?
Here’s what happens: During normal driving, the transmission gets hot just like the engine. To cool the transmission, the fluid is directed through a cooler that sits inside the radiator. When the engine cooling system is working properly, the engine coolant passes over the transmission cooler in the radiator.
Is an external transmission cooler better than in the radiator?
The external cooler not only gives you a much greater surface area to extract heat from, but also doesn’t alter the cooling abilities of the radiator.
Should I bypass my radiator when installing an external transmission cooler?
“Should I bypass a radiator transmission cooler?” No. Automatic transmissions generate a lot of heat — heat that breaks down the fluid that courses through them to make them function. When the fluid breaks down, it can no longer protect the bits that need protecting, so things start wearing and having problems.
How do I lower my transmission temperature?
A proven simple fix is the use of transmission fluid additive on a regular basis. These fluid additives contain coolants specially designed to reduce the temperature of your transmission, especially when it is under pressure from stop-and-go traffic, driving on steep roads, or hauling extra weight.
How long does it take to change a transmission cooler?
The timing will also vary depending on your vehicle model, year, and damage condition. On average, installing a new transmission cooler line on any auto vehicle takes a minimum of 1 & 1/2 hours to a maximum of 2 hours.
Where is a transmission cooler located?
The cooler for the automatic transmissions are placed inside the radiator, the reason behind this is the antifreeze provides the perfect environment. It warms the transmission up with it’s cold and keeps it from getting too hot in extreme heat.
How do I know if my transmission cooler is leaking?
One of the more obvious signs of a failing transmission cooler is a leaking transmission cooler line. If you see pinkish or reddish-brown liquid under the front of your car or under the transmission, you likely have a leaking line on your hands.
How do you know if your transmission is overheating?
- A sudden experience of a burning odor inside and outside the vehicle.
- The gears “slipping” when accelerating or decelerating.
- A feeling of hesitation or delayed gear shift when you are driving.
- Any grinding or shaking sensation that occurs while accelerating or while idling.
At what temp does a transmission overheat?
The optimal temperature range for transmission fluid is 175 to 220 degrees. Above that, for every 20 degrees bad things happen, starting with formation of varnish at 240 degrees, followed by seals hardening, plates slipping, seals and clutches burn out, carbon is formed, and, ultimately, failure.
What would make your transmission run hot?
- Transmission Fluid Problems.
- Driving in Hot Weather.
- Towing Heavy Loads.
- Driving in Heavy Traffic.
- Transmission Slipping.
- Low Transmission Fluid Level.
- Burnt Transmission Fluid.
- Solenoid Malfunction.
Can I drive with a broken oil cooler?
You can manage the car with a bad oil cooler as long as you don’t need to do any tasking driving. Although the car may not overheat immediately, and it might take some time for the effects to manifest, you want to sort the issue ASAP because you run the risk of irreparably damaging your vehicle over time.
What happens if my oil cooler is bad?
When an oil cooler fails, it can force all the coolant out of the engine and raise the risk of an overheated engine, which may lead to possible engine damage. If the leak is significant, you’ll notice coolant on the ground or see steam gushing out from underneath the hood.
How long does it take to change an oil cooler?
Because the oil cooler is buried under the intake manifold, turbocharger and oil filter housing, the typical labor time to replace a failed cooler with a factory replacement is about 8 hours.
Can air get trapped in transmission?
Bubbles on the transmission dipstick indicate issues in the transmission. It may result in catastrophic damages if not handled on time. The common causes of these bubbles are low or overfilled transmission fluid and air in the system.
What is the transmission cooler called?
Plate & Fin Coolers The cooler itself almost appears to look like a radiator in appearance. The plate & fin cooler is more efficient than the tube & fin cooler because it is larger and has more surface area for more transmission fluid to cool on.
How does an aftermarket transmission cooler work?
A transmission cooler operates like a heat exchanger mounted adjacent to your car’s radiator. Hot transmission fluid flows through the unit and comes in contact with a series of fins or plates. The resulting heat dissipation cools the liquid as it cycles back into the transmission.
Is a bigger transmission cooler better?
Selecting a Cooler Size For high performance street cars or trucks that are subjected to heavy loads or towing, bigger is always better.
