About the NP236

The Np236 transfer case was manufactured by New Venture Gear: This model is chain driven. The NP236 is Auto 4WD and electric shift. It was used in Chevrolet S10 Blazer and S10 Pickups. Chevrolet started using this transfer case in 1999 models.

The NP236 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, auto 4wd and 4 low. The units are provided with 27 spline front output and utilizes a rear slip yokes.

Potential problems with the NP236 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, don't leave home without it. Another problem associated with the NP236 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 NP236 is also susceptible to problems caused by running the NP236 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 clutch, 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 NP236 transfer case to fail. Recommended fluid for the NP236 transfer case is automatic transmission fluid (ATF).
