A manual transmission is a gearbox located between the engine and the driving wheels. It allows the engine to transmit power to the wheels through a series of gears. Different gears determine the ratios between the engine RPM and the wheel RPM. Manual transmission fluid lubricates gears, bearings, shafts, and other internal components. Over time, heat, pressure and friction cause the additives to break down in the manual transmission fluid. In addition, small particles of metal may come off of the gears as they wear and these particles can mix with the fluid. Fluids can also become contaminated with moisture. Replacing the fluid in your manual transmission at the manufacturer’s recommended intervals can help prevent premature wear and damage caused be contaminated and/or broken-down fluid.

The fluid level is checked for level and condition and it is recorded. The old fluid is removed from the manual transmission and replaced with new fluid that contains the correct additive package to keep the manual transmission operating properly.
