A permanant solution to a growing problem.  As these trucks are getting a few years older, the transmission cooler lines can start to develop leaks.  This is more common in cold weather as the rubber hose on the line shrinks and allows leaks around the factory crimp.
 
Install our repair kit for a no hassle repair you wont have to worry about again.  Constructed of D.O.T. approved hose able to withstand pressures nearly 2000 PSI.
 
Cut the factory line 1/2" from the factory crimp and install these lines.  Properly sized and ready to install.
