Transmission gels are specially formulated lubricants designed for use in automatic transmissions to reduce friction and wear, extend the lifespan of the transmission, and improve overall performance. These gels are typically made from a blend of synthetic and mineral oils and contain additives that help to stabilise viscosity, prevent foaming, and protect against corrosion. Transmission gels are available in a range of viscosity grades to suit different types of transmissions and driving conditions. They are an essential product for anyone looking to maintain the health and longevity of their vehicle's transmission.
