Top best answers to the question «How do transmission cooler lines connect to radiator»

The hoses traveling from the transmission to the radiator are called transmission cooler lines. They channel hot transmission fluid to the radiator, where it is cooled, then return it back to the transmission. They typically resemble brake lines and are made of metal.

Transmission coolers do not attach to the radiator. They attach in-line with the transmission fluid return line. It is common for an OEM transmission cooler to be built into the radiator tank to be cooled by the coolant in the radiator.
