4WD Transmission Fluid and Gear Oil

Once you’ve installed or repaired your drivetrain components, you’ll need high-quality oil to keep them running well. Transmission oil is a must to lubricate the gears, bearings, clutch packs and other metal parts so they shift smoothly without grinding down. Advance Adapters offers the highest-quality Red Line gear oil for transfer case and transmission use. Add them as part of routine maintenance or following a conversion so your drivetrain runs better and lasts longer.

Getting the Right Oil

The fluid type and capacity can change within a transmission series. For example, the NV4500 oil capacity is four quarts for a stock transmission and five quarts for an NV4500HD 4x4. Using the wrong fluid or overfilling/underfilling can cause serious damage.

We stock an assortment of full-synthetic 4WD gear oil to suit your setup. Our search filters easily direct you to the correct AX15 fluid type, NV3550 transmission oil or anything else you need. Specialty lubricants are also available such as Red Line Heavy Shockproof Atlas transfer case fluid for off-roading and D4 ATF Flat Tow Oil for hauling. Select fluids are sold in five-quart jugs to save money.
