About This Unit
The NP149 (New Process 149), also known as NV149, was introduced as the OEM transfer case in GM’s full-time AWD SUVs and trucks from 2001–2007. Common applications include the Cadillac Escalade (including ESV and EXT), Chevrolet Silverado SS, Avalanche 1500, Suburban 1500, and GMC Yukon Denali and Sierra Denali. The NP149 was commonly paired with 4L60E and 4L65E transmissions and is known for its smooth, automatic torque distribution through a viscous clutch coupling.
Engineered originally with a light duty magnesium housing and a 2.72:1 planetary low-range gear ratio, the NP149 provides seamless AWD operation under all road conditions.Common issues with the NV149 include viscous coupling failure, leading to symptoms like grinding noises during turns or front tire hopping, especially after extended driving. These problems are often due to the coupling not unlocking properly, resulting in drivetrain binding. Our remanufactured 149 transfer cases address these concerns by incorporating upgraded components and rigorous testing to ensure durability and performance.
This GM transfer case is currently on sale — making now the perfect time to replace or upgrade your OEM unit with a fully remanufactured model built to exceed factory standards.
