Do you have leaky transmission lines? This is the last set of transmission lines you'll ever need. In a joint venture between Speed Stop Auto Repair and Masonbilt Diesel Performance, we have developed the most durable, serviceable, and the ONLY DOT-approved transmission line set with a LIFETIME warranty. All of these lines are made by hand, in-house, with equipment we own, meaning that we have complete control over quality and know that each line is being made to our exact specifications
Features:
- 5/8" flame and abrasion-resistant hose rated for 4000psi- SIGNIFICANTLY more than both OEM and built transmissions require

- Our own specific line lengths and fittings tailored specifically to each truck
- Limited Lifetime Warranty
Fitment:
- 2001-2002 GMC Sierra 2500/3500 6.6L Duramax LB7
- 2001-2002 Chevrolet Silverado 2500/3500 6.6L Duramax LB7
Included:

- Instructions
Note:
- 2001-2002 Allison transmission cooler inlet/outlet fittings had a smaller 3/4" thread diameter than later 7/8" units. If you think your transmission has been swapped with a later unit, you can measure the original trans cooler fitting in the transmission or reference the build plate found on the passenger-side of the transmission
- If you have an aftermarket radiator, you will need M22 fittings instead of OE-style to JIC. This can be easily determined if your radiator has a hex-shaped fitting BEHIND the OE-style transmission cooler fittings
