Power steering fluid and transmission fluid are completely different fluids with different chemical compositions and properties. Using the wrong fluid in your transmission can cause serious damage, including:
* Friction and wear: Power steering fluid has a lower viscosity than transmission fluid, which means it won't lubricate the transmission components properly. This can lead to excessive friction and wear, causing premature failure.
* Sealing problems: The seals in your transmission are designed to withstand the specific properties of transmission fluid. Power steering fluid can break down these seals, leading to leaks and fluid loss.
* Transmission damage: The wrong fluid can also affect the hydraulic system of your transmission, leading to problems with gear shifting, slipping, and other issues.
Using the correct fluid is essential for the proper functioning and longevity of your transmission. Consult your owner's manual or a qualified mechanic to determine the correct transmission fluid for your 1987 Ford.
Always use the recommended fluid for your vehicle.
