Automatic transmission oil cooler pipes
Automatic transmission oil cooler pipes are important components of the transmission cooling system. They are responsible for circulating transmission fluid (ATF) from the automatic transmission to the oil cooler and back.
Description and design
Automatic transmission oil cooler hoses are usually made of a flexible rubber material such as nitrile butadiene rubber (NBR). They have two ends, one of which is connected to the automatic transmission, and the other to the oil cooler. The pipes often have fiber-reinforced walls for increased strength and durability.
Depending on the design of the automatic transmission and the oil cooler, there may be two or more pipes. In some cases, the pipes may have built-in temperature or pressure sensors.
Function
Automatic transmission oil cooler pipes circulate ATF through the transmission cooling system, which includes an oil cooler. ATF absorbs the heat generated by the automatic transmission during operation. It circulates through an oil cooler mounted outside the vehicle, where it is cooled by air flow. The cooled ATF is then returned to the automatic transmission.
Replacement
Automatic transmission oil cooler pipes must be replaced periodically due to factors such as aging, heat and vibration. Worn or damaged hoses can lead to ATF leaks, automatic transmission overheating, and other transmission problems.
Signs of wear on the automatic transmission oil cooler pipes include:
*Reduced ATF level
*ATF leaks
* Gear shifting with delay or slipping
* Increased noise when shifting gears
* Automatic transmission fault indicator lights up
Replacing automatic transmission oil cooler pipes usually requires removing the lower crankcase protection and disconnecting the pipes from the automatic transmission and oil cooler. New fittings should be tightened to the specified torque.
