Transmission & Gear Fluids

Transmission & Gear FluidsGear Oil and Transmission Fluid are typically used to lubricate the gears and moving parts of your transmission, transfer case and differential. Neglecting to upkeep the transmission fluid and gear oils will result in inefficient vehicle operation, as the liquid becomes thick over time and cannot spread out to all the gears, or parts of the transmission. At Auto Barn we carry a variety of gear oil and transmission fluids for trucks and European vehicles by Mobil 1, Royal Purple, Pentosin, Valvoline, B and M Shifters, and Lucas Oil. Plus transmission additives to protect your gears and moving parts from wear by Lubeguard, Lucas Oil, Gunk, and Dr. Tranny. Check out our wide variety in any of the sections below!
