Starightforward digital/online installation instructions. All lines fit as they should no excess line just the right length. Quality of the lines and fittings are great. Matched this up with PPE bar and plate trans cooler for my 07 LBZ replacing common leaky trans lines. Upgraded trans cooler while doing the lines. No leaks so far, happy with the lines so far.

Fleece performance Tranmission lines
Isham (Mississippi) | September 7th, 2021
I have had nothin but leaks and leaks out the factory lines. Have replaced radiator and transmission lines 3 times. Then discovered these lines. Best product for the fix! You won’t regret getting these! Easy install and comes with instructions if you need them!
Good upgrade
CBark (Utah) | September 1st, 2021
Bought these along with the xtra cool transmission cooler. They feel high quality for sure and defiantly will flow more fluid. Install was easy. My thought on the people with negative experiences is they probably ordered the wrong line set and the one guy who had a failure, there’s always going to be some parts that fail, just the name of the game. My install went super smooth. Transaction went well, got parts in 3 days with free shipping. Order 1491322
