$79.48The Story
One of the most plaguing issues of owning an Allison equipped Duramax truck are the leaky transmission cooler lines. This kit from Merchant Automotive will eliminate your woes once and for good.
A permanent 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 the Merchant Automotive repair kit for a no hassle repair you won't have to worry about again. Constructed of D.O.T. approved hose and able to withstand pressures of nearly 2000 PSI. Cut the factory line 1/2" from the factory crimp and install these lines. Properly sized and ready to install.
Add the Mini Tube Cutter, 1/8"-5/8, in the kit to insure proper cutting of your transmission lines for a clean installation.
