2001-2004 GM Duramax 6.6L LB7 Complete Transmissions
The factory transmission equipped on your 2001-2004 GM 6.6L Duramax LB7 build becomes a weak point after you add increased levels of horsepower and torque to the engine.

These complete transmissions for your GM 2500/3500 drop right into place of your Sierra/Silverado's stock components and will handle the huge levels of power your truck is throwing down.
