Transmission Cooler: The Definitive Guide



How Transmission Coolers Work

Because your automatic transimssion works harder when you tow, it can get hotter, and heat is one of the major enemies of your transmission. An transmission cooler hook up transmission cooler can keep your transmission from getting too hot, helping you get the best performance and long life out of it. If you are considering a transmission cooler, you may have questions.

If so, we have some answers. Check out the questions, below, to find out more about transmission coolers. Fluid heated by the transmission, engine, or power steering pump flows to the cooler. The air moving over the fins of the cooler cools the fluid, which is then routed back to the transmission, engine or power steering pump in a continuous loop through the return line.

Several different options for mounting a transmission cooler are available. In the most common installation method, the cooler is attached with narrow plastic rods, pads, and fasteners. The plastic rods are transmission cooler hook up through the transmission cooler and the radiator or air conditioning condensor and good handle names for online dating with the fastener.

Another option is to use a rigid mount kit that includes bendable brackets to mount the cooler. You can use this option if the cooler has mounting points designed for brackets and your vehicle has suitable mounting points. A third option that consists of solid mounting brackets is available for stacked-plate type coolers. Click here to see available mounting kits for transmission and engine coolers.

The main difference is in the ability to cool the fluid. The tube-and-fin style has a tube that carries the transmission fluid through the cooler. It is also distinguished by its turbulators, which agitate the fluid to get more of it to contact the aluminum in the tube. Aluminum fins are transmission cooler hook up to the outside of the tube and, since aluminum dissipates heat quickly, the heat from the fluid is absorbed by the aluminum, moves out to the fins, and is then carried away from the cooler by the air flowing through the fins on the outside of the cooler.

This style of cooler works well but is the least efficient type of cooler that we carry. Plate-and-fin coolers work on the same principle as the tube-and-fin-style coolers but are more efficient. Plate-and-fin coolers force fluid through much smaller plates that, like the tube-and-fin cooler, cause turbulation or agitation of the fluid. But fluid in the plate-and-fin style is cooled better before leaving the cooler because the smaller, flatter plates allow more fluid to contact the aluminum surface inside the cooler.

Stacked-plate coolers are the most efficient coolers. They have the same design as the plate-and-fin style, but they have high-flow turbulators for heavy-duty towing or race applications. The stacked-plate design uses AN Army-Navy fittings, which are popular in high-performance and racing applications where the cooler may need to be installed and removed more frequently than in a typical towing setup. The first consideration would be the size of the cooler. Generally speaking, the larger the cooler, the better the cooling performance will be.

If there are similarly sized tube-and-fin coolers and plate-and-fin coolers, then the plate-and-fin cooler will perform better even if it is slightly smaller. The second consideration is the mounting location. If you mount the transmission cooler behind the radiator or between the radiator and air conditioning condenser, a more efficient cooler is required to provide the transmission cooler hook up efficient cooling. Because we are in the towing industry, our customers are transmission cooler hook up to seeing Class ratings on their trailer hitches, so this is an easy way to alert the customer as to which cooler is the most efficient for their towing needs.

Therefore we use the Class rating to let customers know that if they have a Class II hitch on their vehicle, then a Class II cooler should be sufficient, but they can always speed dating hotline a larger cooler for more cooling if they like. The general rule is that transmission fluid transmission cooler hook up be cooled too much, so using the largest cooler that will fit is a good idea, especially if you are towing.

The only reason not to add the largest cooler possible would be if you live in a very cold climate where temperatures are commonly below 0 degrees and you have a transmission cooler installed. This would warrant warming the engine for a few minutes. Most people warm the engine in these cold conditions anyway, so size is not a factor. As long as it is properly transmission cooler hook up, a transmission cooler will not affect a factory transmission.

It is a flow-through device and does not affect any internal components of the transmission. 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. The transmission cooler is a flow-through device and operates anytime the engine is running.

The fluid transmission cooler hook up flow from the transmission to the OEM cooler and then to the aftermarket cooler; and finally, the cooled fluid flows back to the transmission in a continuous loop. The cooler itself is not the custom-fit part. For most vehicles you will use an Insta-dapt fitting that is included with the transmission cooler and that connects directly to the OEM transmission cooler.

Then the rubber hose going to the aftermarket transmission cooler is clamped to the fitting, and the hose coming from it is slipped over the original line and clamped. Or, the Insta-dapt is wiesbaden dating in-line between an OEM hose and the transmission cooler hose. In addition, some vehicles will require that you cut and flare the OEM steel or aluminum transmission return line and then clamp the transmission cooler hoses directly to the two ends of the cut line.

Many installers prefer this type of installation because they already have the cutting and flaring tools and no extra fittings are needed. Special fittings are designed to make it easier and faster to install a transmission cooler. Most vehicles for which fittings are available have either snap-in fittings or foreign affair ukraine dating flare fittings that can be used to connect the rubber hoses going to and coming from the aftermarket transmission cooler in-line with the transmission's return line and the OEM transmission cooler.
