As some of you may know we also own and operate a transmission repair shop. We've been noticing alot of cooler line failures on the 06 and newer Allison equiped vehicles. We would simply replace the lines with factory new ones only to have them start leaking within 20,000 miles. Well here is the fix. Let us know if you have any questions. We are stocked and ready to ship.
