An automatic transmission fluid leak may develop from the rubber section of a transmission cooler line. In some cases the rubber section of hose can be replaced. In others, the complete cooler line must be replaced to correct this type of leak.

    I have developed a fluid leak where the rubber meets the metal on the upper transmission line on the drivers side that runs under the breather filter from motor to air filter.
