It is not advisable to go without changing transmission fluid for 8 years. Transmission fluid primarily serves to lubricate, clean, and seal the transmission. Over time, the fluid quality deteriorates, and impurities may form. Here is some information about transmission fluid: 1. Functions of Transmission Fluid: It is an oil product that keeps the gear system clean, lubricates to prolong the lifespan of transmission components, provides effective lubrication even in low temperatures, and reduces fluid loss under harsh operating conditions. 2. Characteristics of Transmission Fluid: Most transmission fluids on the market are compatible with current automatic transmissions. However, each automatic transmission design has unique technical requirements. Even the same transmission model used in different vehicles may vary in torque, weight, speed, and structure. Therefore, manufacturers specify their own dedicated transmission fluid.
