Transmission Coolers in Louisville, KY

There’s nothing more deadly to your automatic transmission than heat. But your friends at Cottman in Louisville, KY can help you protect your transmission against heat damage, to keep your transmission operating for years to come.

To help reduce that heat, nearly every automatic transmission has a transmission cooler, usually mounted in one of the radiator tanks.

Hot transmission fluid flows into the transmission cooler, where it’s surrounded by coolant. That heat is absorbed by the coolant, where it’ll eventually be released to the air passing over the radiator fins. The cooled transmission fluid then returns to the transmission to keep the transmission operating at a safe temperature.

On most cars, that factory cooler provides enough heat transfer to protect the transmission. But over time those coolers can plug or crush, restricting flow and reducing the amount of heat it can release.

On other vehicles, the load placed on the transmission ends up generating more heat than the factory cooler was designed to handle. Cars that pull campers or work trucks are common situations where the factory cooler just doesn’t provide adequate heat transfer to keep the transmission cool enough.

In those situations, the answer is usually simple enough: add an auxiliary cooler to the system. These are generally small heat exchangers that replace the factory coolers. They usually mount in front of the radiator, and transfer heat from the transmission fluid directly to the ambient air passing over their fins.

Our technicians at the Louisville, KY Cottman center can examine your car or truck, and let you know whether an auxiliary transmission cooler would be a worthwhile investment to help protect your automatic transmission. And, if you decide to have one installed, they can take care of finding one with the right capacity, and installing it on your car or truck.

    • Last year we had a transmission that needed to be rebuilt in a 2009 Subaru Forester and brought it to Cottman based on their reviews. Greg and his team were sympathetic to the huge repair bill I was going to have, and looked for any way to safely save money. We also went ahead and replaced the timing belt and water pump based on the mileage. Having never been there before I called a few places to check that their estimate for that wasn't too much. The price was right in line with other reputable shops. 1 year later the transmission is still shifting as it should. Recently the same car had several other issues come up and I decided to try a shop down the street for diagnostics. Some of the numbers seemed a bit steep, so I took the car to Cottman for a second opinion. Greg, John and crew confirmed the issues, but the cost of the repairs seemed on par with my Google searches and I really felt comfortable having the work done there. I told them I need the car to be able to take a trip to Chicago and back, and they listed everything out in order of importance/ safety. To some it up, when we drop our cars off at Cottman, I don't feel like I'm being up sold a bunch services the vehicle doesn't need. And they stand by their work!

    • Have used Cottman transmission several times now on 1998 E150. Always professional, honest & fair priced. Greg will take the time to talk & explain the repairs needed even though the shop is busy. Would be my 1st recommendation to a friend needing repairs!

    • We love Greg and his team. They do a great job with our older vehicles, and they don't nickel and dime us. They are very honest about what needs to be fixed now, and what still has life in it.

    • Cottman handled my manual clutch replacement with exceptional service. After replacement, the truck drove like new again with the exception of a newly leaking axle seal. Cottman continued to take the truck in to resolve at no additional charge. Exceptional service and communication throughout the entire process. I highly recommend.
