About the NP261 Transfer Case
The NP261 transfer case was manufactured by New Venture Gear. This model is chain driven. The NP261 is 4WD with manual shift. The NP261 was used in Chevrolet and GMC in Silverado’s and GMC Sierra. This unit was utilized beginning in 1999.
The NP261 was manufactured with left side drop output and has a low gear ratio of 2.72 to 1. This unit has combination of 2 high, 4 high, neutral and 4 low. The units are provided with 27, 29, and 32 spline front output and utilizes a rear slip yokes. Some pickups are supplied with heavy duty (HD) and extreme heavy duty (XHD) heavy duty version with wider chains, sprockets and HD planetary.
Potential problems with the NP261 Transfer Case
This unit can have issues with premature case failure caused by the oil pump housing wearing a hole in the case, causing loss of fluid and transfer case failure. Midwest provides a machine case protector plate to solve this problem. A better option is to replace the rear case with the new design shown on the left, don’t leave home without it. Another problem associated with the NP261 transfer case is input and or output bearing wobble wearing out the case. The case material is magnesium,which can build up heat in the unit causing failure of range fork and range hub, we recommend that these items be replaced during the rebuild cycle. The NP261 is also susceptible to problems caused by running the NP261 transfer case on hard surfaces like concrete or asphalt. Run 4WD only on loose dirt, snow, mud, sand or grass as the different wheel speeds in turns can put excessive torque loads on chain and sprockets.
If you have purchased your vehicle used the very first order of business is to double check the tire diameters. Used car dealers may have mismatched the tires to make the sale. Mismatched tires will cause the NP261 transfer case to fail. Recommended fluid for the NP261 transfer case is automatic transmission fluid (ATF).
