How to Extend Your Transmission Life

Transmission LifeYour transmission is like your car’s nervous system. It interplays with almost every other system in the vehicle, and transmission problems can leave you doing more walking than driving. Signs you might have transmission trouble include:
  • Strong odors
  • Hesitation
  • Discolored fluid
  • Burning smell
  • Check engine light
  • Slow acceleration 
  • Reduced fuel mileage
  • Fluid leaks
  • Grinding noises
  • Shaking
  • Whirring sounds 
  • Slipping gears
  • Dragging clutch (manual transmissions only)
If your transmission is already showing one of the problems listed above, you likely already need a repair, which can be very expensive. The best way to care for your transmission is to prevent problems before they start. With just a few easy steps, you can keep your transmission functioning smoothly and efficiently:
  • Replace transmission fluid according to OEM specifications.

Your vehicle’s manufacturer will include their recommended service interval for replacing transmission fluid in your vehicle’s service manual. Each vehicle model’s recommendation can be different depending on vehicle type, transmission type, etc. If you’re not sure when to change your transmission fluid, do it at least every 40000 miles.
  • Upgrade to synthetic transmission fluid.

Synthetic transmission fluid resists oxidation, allows gear to shift easier, doesn’t need to be changed as much, and doesn’t break down so severely at high temperatures. Plus, since synthetic transmission fluid is not petroleum-based like regular transmission fluid, it’s better for the environment and your car’s carbon footprint. However, not all vehicles can use synthetic transmission fluid, so do your research before pouring it in.
  • Adjust the transmission bands.

If you are driving an older vehicle or heavy-duty truck, you may have heard of adjusting the transmission bands. This old trick won’t work on newer cars, but adjusting or tightening the transmission bands on older vehicles at least every 60,000 miles can prevent some issues.
  • Check the transmission fluid.

It might seem like this goes without saying, but keep a check on your transmission fluid level. When it is low, top it off with extra fluid. If it is constantly below where it should be, take your vehicle to an experienced mechanic immediately.
  • Only use transmission fluid recommended by the OEM.

There are many varieties of transmission fluid on the market, and they are all made for different purposes. Only use the type of transmission fluid that your vehicle OEM approves. Using unapproved transmission fluid could cause your transmission to seize up and leave you stranded.
  • Never mix different types of transmission fluid.

Just like you should only use the OEM recommended transmission fluid, you should also never mix different types of transmission fluids. Each transmission fluid is designed specifically for its purpose, and mixing different transmission fluids could cause undesired effects or even a breakdown. 
  • Replace the transmission filter and/or screen as recommended by OEM.

Whether your vehicle has a transmission filter or screen, clean it and replace it at the interval recommended by the vehicle OEM. Depending on the type of transmission your vehicle has, you may need a mechanic to do this task.
  • Clean the transmission pan magnets.

Magnets on your transmission’s pan are used to capture metal fragments, so they don’t enter the transmission and hamper its functioning. These fragments need to be cleaned out from time to time to ensure the magnets can continue working. You may want a mechanic to do this as well.
  • Use a transmission conditioning product.

Many transmission conditioning products are on the market these days. These products can not only restore performance, but some can fix small leaks in your transmission. Only use conditioning products made for your vehicle type. If you are unsure what to use, consult with your mechanic or auto parts store representative. When it comes to transmissions, an ounce of prevention is worth more than a pound of cure. Repairing your vehicle’s transmission after the damage has occurred is prohibitively costly and time-consuming. Instead, treat your transmission well by following recommended service schedules and it will last you the entire life of your car.
