Manual Transmission Fluid
Why You Might Need Fresh Transmission Fluid
As the fluid deteriorates, it will likely lose its lubricating and cooling properties. Additionally, it can collect minute metal shavings from moving parts and gunk that has accumulated inside the transmission, which can affect the quality of the shifts.
If your transmission shifts slowly or slips out of gear, this could be a sign that it needs new fluid, but it could also be a sign of mechanical trouble. While new transmission fluid is not a cure-all for technical problems, it can improve shift quality and increase the transmission’s likelihood of a long, productive life.
While it may sound reassuring that transmission fluid is good for 150,000 miles or the life of the vehicle, many mechanics believe this is too risky and that fluid should be changed more frequently. Similar recommendations are frequently made by repair shops regarding “lifetime” engine coolant.
Here Is Quick Car Maintenance Tip
Keep the battery clean.
Corrosion (which appears as white or bluish powder) can form on your battery’s terminals. If you do not maintain them properly, the battery may develop a crack or cease to function, 
leaving you stranded. Given that a good car battery can cost upwards of $100—and a tow can cost even more—investing $5 in a wire brush and keeping the terminals clean is a good investment.
- Battery Maintenance Tip: Test and inspect your battery twice a year for corrosion.
