Merchant Automotive Transmission Cooler Line Repair Kit 01-05 6.6L GM DuramaxOne 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

Very Impressed, Great Deal
Color: Black, Size: Large
Purchased this as a gift for my travel clients who are going to Greece and I am so glad I did! At $9.99, it is such a great deal! And I love that it has RFID blocking, as well as a Bluetooth tracker, just in case. I'm excited to hear feedback from them and hoping the bluetooth tracker actually works! But so far, very impressed.
