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.

    There is a small leak from the back transmission coolant line. How can this problem get resolved without the engine having to be removed?

    The rear coolant line going into the transmission leaks, . Not sure how to fix it? Can't get a wrench on the damn thing. Trying to check out this web site to see if the solution is to pull the Engine Cradle and work from there?

    Upper tranny cooler line pulled out of quick connect at transmission. Lost all fluid within a minute. Good thing it happened in my driveway and not on a highway ir a $25 parts could have caused a $3500 trans replacement. Been a cadi guy all my life and the 2008 DTS has been a money pit...
