How to Maintain Your ZF Transmission

How Do Transmissions Work?

Maximizing the efficiency of your engine by achieving low fuel consumption is your transmission’s main prerogative. Your transmission knows when to shift at the precise time to reduce the RPMs (revolutions per minute). Lower RPMs are what helps increase your MPG (miles per gallon).

I’ll try and use less car speak to explain.

Your car is one heavy beast, we all know that and so does your transmission. In order for your car to begin accelerating from a standing position, it requires a lot of torque or high RPMs. As your car gains momentum and speed, your car needs less RPMs to move forward. This is when your car automatically (unless you have a manual transmission) shifts to the next gear.

This is similar to the gears on your bike. Starting in a low gear allows you to pedal faster from the start. The more momentum you have the easier it is to shift to a higher gear. Higher gears allow you to move faster with less pedaling.

About ZF Transmissions

If you own a European made vehicle, you most likely have a ZF transmission.

ZF Friedrichshafen AG is a global leader in driveline and chassis technology. The corporation has 122 production companies in 26 different countries. According to ZF, it is one of the ten largest automotive suppliers worldwide, which is why most European made vehicles contain a ZF transmission. They are known for high performance transmissions while still providing ways to reduce fuel consumption. You can see from the video below (don’t mind the trippy music) that ZF transmissions improve the “downspeed” of a transmission, allowing for greater efficiency.
 

Ok, enough of the bragging. Now that you know a little bit about who makes your transmission and how it works, what are some way you can help maintain the performance of your transmission?

Fluid Change

A recommended fluid change every 40,000 miles will help keep the transmission healthy. This will reduce the amount of dirt and buildup that can cause your transmission to slip or grind it’s gears.

Filter Change

Many vehicle owners feel that the filter doesn’t need to be replaced if they regularly change the transmission fluid. However, metal shavings often splinter off the gears and will stick to your transmission filter along with everyday dirt and grind from the road. Even with a transmission flush, these shavings will still stay attached to the filter. The combination of dirt and metal shavings will really slow down the performance of the vehicle and cause your transmission to work harder. It can also create larger problems with your engine if you start experiencing signs of slow acceleration, gears slipping or randomly down shifting, or stalling.

That’s why we recommend a full transmission service of changing out your transmission fluid and replacing your filter at the same time. This can save you money in the long run by allowing the highest possible MPG for your vehicle and help avoid other costly repairs.
