How Does a Transmission Cooler Work? Fluid heated by the transmission, engine, or power steering pump flows to the cooler. Air flowing over the fins of the cooler carries away heat and cools the fluid flowing within the fins. The cooled fluid is routed back through the transmission via the return line.
How is a transmission cooled?
In almost all vehicles with an automatic transmission there is a transmission cooler placed inside the radiator. … The auxiliary cooler is cooled by air flow while the cooler inside the radiator is surrounded by antifreeze which is a controlled environment.
What makes transmission overheat?
Low fluid levels or old transmission fluid causes friction between the parts and causes overheating. Fluid problems are the most common reason for transmissions overheating.
Is it possible to over cool a transmission?
Can you over cool the transmission fluid? Answer: Transmissions are not highly sensitive to cool operating temperatures. However, in sub-freezing (20-30°F) weather conditions, transmission fluid can actually gel up in an external cooler and cease to flow, causing damage.
Can I run two transmission coolers together?
as for routing, just run them all in line with each other. say you are keeping the radiator cooler, take the outlet of that cooler and hook it to the inlet of the new trans cooler, take the outlet of that cooler and hook it to the inlet of the next trans cooler and then back to the transmission.
Can a transmission cooler be too big?
Too big could be a concern if mounted in the front of the rad creating a loss of air flow to keep the engine cooled . Years ago , GM released a TSB about overcooling the transmission in cold climates . Transmission fluid would actually turn to somewhat of a gel .
Does transmission cooler need a fan?
If you are in a situation where you cannot use a cooler in front of the car where it can get enough air flow, it is recommended to use a cooler with a fan. Most common cars will not need to deal with a remote mounted transmission cooler with a fan based on the simplicity of most cars.
Does transmission fluid need to be cooled?
The healthy range of temperature for transmission fluid is about 71 to 93 degrees Celsius. If your transmission fluid exceeds this temperature, it will begin to burn. … Not only can burnt fluid not effectively cool your transmission, it can actively damage it, even after is has cooled down.
