Transmission Repair & Service

Why you should Flush out your Transmission Fluid

Your transmission’s vital parts get clogged with sludge and varnish deposits because, just like engine oil in your car’s engine, automatic transmission fluid suffers from heat, friction and electrochemical degradation. In fact, nearly nine out of ten transmission failures are due to overheating and fluid contamination.*

However, unlike oil, which can be completely drained from your car’s engine, most transmission fluid cannot be drained. Instead it stays in the torque converter, valve body and transmission lines, making a complete fluid drain impossible. Typical transmission service removes only 25% of the contaminated transmission fluid. Adding new fluid to the remaining contaminated fluid can actually cause sludge and varnish deposits to clog filters and further restrict fluid flow. This can result in a serious malfunction or even complete failure of your automatic transmission.

Now you have an option. At Doc Motor Works, our transmission fluid exchange safely removes most, if not all, contaminated fluid as well as varnish and sludge deposits. Our transmission fluid exchange cleans the transmission cooler and lines, valve body and torque converter and also removes those wear metals that slowly grind away your transmissions’ internal components. Our transmission fluid exchange thoroughly cleans your car’s transmission and protects it with fresh fluid and conditioners that revitalize the seals and o-rings. If your vehicle’s transmission is showing signs of contaminated fluid, slippage, rough or hard shifting, try this service. If its been more then 30,000 miles it’s time for a transmission fluid exchange. It may help you avoid the cost of major transmission work or even prevent the need for a new transmission.

More about transmissions.

Transmissions are heavy duty pieces of equipment that are designed to last a long time for most Illinois drivers. But like any other machine, they’ll eventually wear out and need repair. So let’s focus on what you can do to push that day off as far as possible.

The first thing you can do is to make sure your transmission always has enough fluid. Transmission fluid cools and lubricates the transmission. When there’s not enough fluid, the transmission will run hotter and wear out sooner.

The transmission fluid also provides the pressure needed to transfer power from the engine to the transmission. Not enough fluid, and your transmission won’t shift properly.

Your area service center at Doc Motor Works will check your transmission fluid level with a full service oil change and top it off if needed. If you see any transmission fluid on the driveway it is a reddish color have us inspect it for a leak. A gasket, hose or seal could be leaking and may need to be repaired.

The next thing you can do to prolong the life of your transmission is to replace your transmission fluid on schedule. As you can imagine, all those gears grinding on each other result in lots of little bits of metal in the fluid. The more there is, the faster the transmission parts will wear out.

Transmission fluid also contains detergents and other additives to protect your transmission. These additives are depleted over time, so old fluid doesn’t protect as well as new fluid. Your owner’s manual or Doc Motor Works service advisor will have a recommendation for when you should have a transmission service.

If your transmission isn’t shifting as smoothly as it should, or if you suspect a transmission leak, let our Shorewood Illinois service center take a look at it. And ask if it’s time for a transmission service. Regular maintenance and taking care of small leaks right away will help your transmission last as long as possible.
