Deviant Race Parts LEAK FREE 5/8" High Performance Transmission Repair lines for 01-05 GM 6.6L Duramax equipped Pickups with the Allison 1000 Transmission.

GM's factory transmission lines leave something to be desired. DRP saw a need to build a high quality, LIFETIME WARRANTED, part that completely replace the OEM lines. With thousands sold, we can say we've solved the problem.
