2006-2010 1/2" Allison transmission cooler hose set #10300

I fought those sorry factory transmission cooler lines for years. Had them replaced under warranty, then replaced them with the new improved lines from GM at my expense and they still leaked.

I finally heard about Red's lines and ordered a set, a little bit of a struggle to put on up front as it is pretty tight in there. They absolutely do NOT leak, it's wonderful, the driveway and garage floor are clean and dry for the first time in years. Thanks Red.
