NP261-NV261 Frequently Asked Questions
Which Trucks Have the NP261 Transfer Case?
Many manufacturers have used NP261 transfer cases since their arrival in 1999. They are used on most 4x4 pickup trucks across the board, including those from Ford, Chevy, and General Motors. GM and Chevrolet used them from 1999 through 2007, so if your truck was manufactured then, it probably has an NP261.
How Much Does an NP261 Transfer Case Weigh?
One of the benefits of the 261 HD GM transfer case or the NP 261 LD GM transfer case is that they weigh only between 70 and 80 pounds. Ours are just as light, but we repair all the typical defects and rebuild every part in them for extended, improved performance.
What Fluid Goes in an NP261?
The specific type of transmission fluid you need depends on your specific transfer case, make, and model. However, a New Process 261 transfer case, including NP261HD, NVG 261, and 261 LD GM transfer cases, use Dexron III or higher transmission fluid mostly. The wrong fluid can ruin your case.
What Are Common Problems of the NP261 Transfer Case?
There are many common issues with these cases. First, the oil pump housing can wear a hole in the case, causing fluid loss and failure. Input and output bearing wobble in the magnesium case can build up heat, eventually causing failure. We completely replace these parts to overcome these issues.
NP261-NV261 History & Information
The Chevy 261 transfer case was originally produced by a company called New Venture Gear, also sometimes known as New Process. It was a chain-driven module designed for manual-shift 4WD trucks and first appeared on the scene in 1999. They were used on almost every single GM and Chevy pickup exclusively between the years 1999 and 2007, and eventually were picked up by other auto manufacturers, including Ford. Common vehicles it was used in were the Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Silverado 2500, GMC Sierra 2500, Chevrolet Silverado 3500, and GMC Sierra 3500.
The case has a 2.72:1 low gear ratio with a left side drop output. It offers 4 low, neutral, 4 high, and 2 high combos. It uses a rear slip yoke and comes with either a 27, 29, or 32 spline front output. Pickups that are designed for heavy-duty use had a 261 HD GM transfer case or 261XHD transfer case while the lower-duty trucks came with the NV261LD transfer case. The specific transmissions that were factory mounted to the NP261 transfer case include the 4L60E, NV3500, 4L80E, NV4500, Allison 1000, and ZF6 transmissions.
Despite being designed for heavy-duty use, and being cutting edge at the time, these transfer cases were far from perfect. They did come with a number of flaws, including a weak case, ball-bearing issues, and other problems that could cause the original cases to fail. This is why it's so important to have a properly remanufactured NP261 case rebuild done instead of just a haphazard repair job.
One unique issue with the 261 transfer case is that they are designed to work with very specific tire diameters. Very often, especially if you've purchased a used truck, the dealer will have mismatched tires, which they think will make it sell at a higher value, but mismatched tires put undue wear on the transfer case and can cause it to fail.
Our rebuilt NP261 transfer cases for sale remove the many standard weaknesses of these cases and allow your heavy-duty truck to perform at peak levels without worries about fluid leaks, housing problems, bearing wobble, and other case failures.
