Fresh Fluid is Key
The single most important thing you can do to head off big-bucks transmission repairs is to change the ATF on a regular basis.
Some carmakers have backed down from the unrealistic 100,000-mile transmission fluid change interval recommended in the past. Every 30,000 miles is much more reasonable. If you tow heavy loads in hot weather, you might even think about annual changes. Plus, boats transmissions are very susceptible to water and humidity entering the system. The fluid becomes a milky white and pink color. Not good.
It’s a messy job because there’s no drain plug to change the fluid, but you can do it yourself if you’re so inclined. For example, to change a car’s fluid, you have to get under your vehicle and remove the pan from the bottom of the transmission.
Here’s an article from The Family Handyman Magazine that explains the easy and clean way to change your transmission fluid. The LiquiVac Oil (and transmission fluid) Changing System is featured in this article!
