When not to change trans fluid-Why Change Transmission Fluid Regularly? | Great Canadian Oil Change

Transmission fluid is a slippery liquid that acts as a lubricant for all of the moving parts inside your transmission. In an automatic transmission, this fluid also serves as a coolant and a viscous fluid that transmits power from the engine to the transmission. Just like engine oil, transmission oil additives break down over time and no longer properly lubricate the transmission components or disperse heat evenly from the vehicle. By changing the fluid at the recommended interval, you ensure that your transmission is lubricated properly. To determine how often your transmission fluid should be changed, follow the recommendations of the manufacturer for the make and model of your vehicle.

Transmission fluid is a slippery liquid that acts as a lubricant for all of the moving parts inside your transmission. In an automatic transmission, this fluid also serves as a coolant and a viscous fluid that transmits power from the engine to the transmission.

Just like engine oil, transmission oil additives break down over time and no longer properly lubricate the transmission components or disperse heat evenly from the vehicle. By changing the fluid at the recommended interval, you ensure that your transmission is lubricated properly. To determine how often your transmission fluid should be changed, follow the recommendations of the manufacturer for the make and model of your vehicle. The interval will vary between makes and models.

We also recommend that you get your fluid level checked when you have an oil change done, as there may be no obvious indication that your fluid level is low. Of course, always have your transmission fluid checked if you notice a leak of any kind. We help you choose the Transmission Fluid that is right for your vehicle.

Letting your car run low on transmission fluid can cause the transmission to shift improperly or not at all.

It also can harm the internal parts of your transmission, which will not be properly lubricated. Unfortunately, you may not hear any noises or have other clues that your transmission is low on fluid, until it is too late. So it is important to get it checked and changed when needed. By changing the transmission fluid at the interval recommended, you will avoid both shortening the life of and costly repairs to your transmission. Changing automatic transmission fluid is best left to a technician equipped with the a transmission flusher.

Using the proper equipment will ensure the fluid is replaced more thoroughly and effectively than you could achieve with gravity alone. The only maintenance required between intervals is to check the fluid level periodically. As stated above, letting your car run low on transmission fluid can cause problems. Also, as stated above, it often difficult to know the fluid is low unless it is checked. You may be able to check your own transmission fluid level, depending on the type of transmission you have, and how new your vehicle is.

Follow these guidelines:. Manual Transmission : Not all manufacturers include a transmission fluid dipstick in vehicles with a manual transmission.

Thus, checking the fluid level can be difficult. We recommend that if you own a vehicle with a manual transmission that you ask your technician to check the fluid level when your car is in for an oil change. Automatic Transmission : Vehicles with automatic transmissions may have a dipstick for the purpose of checking the transmission fluid level. Be sure you use the correct dipstick as there may be others, such as a crankcase dipstick.

The transmission fluid on these vehicles can only be checked from under the vehicle. In this case we recommend that you ask your technician to check the fluid level when your car is in for an oil change. For most cars, checking the automatic transmission fluid consists of pulling the transmission dipstick out while the engine is warmed up and running and with the transmission in park. The transmission fluid level is checked as part of the service with every oil change.

When you should or shouldn't change your automatic transmission fluid

Q--I haven't changed the transmission fluid in my Ford Aerostar in more than , miles. It functions fine in all gears, and the color is normal. A friend of mine told me that if I changed the fluid now, the new fluid would have so much "bite" it would cause all kinds of driveability problems, slippage, etc. Is it wise to change the fluid now?

A--This letter is typical. Many others have written asking why their transmissions have failed after having the fluid changed. Before we answer those questions, it is important to review why transmission fluid must be changed periodically. Automatic transmission fluid ATF must transfer the power torque from the engine to the drive line. Under pressure, it controls shifting. It lubricates all the parts in the transmission.

It cools the transmission. And it keeps everything inside clean. Though the original transmission fluid was derived from whale oil, today most ATF is 85 to 90 percent petroleum-based mineral oil with 10 to 15 percent additives.

Though there are some synthetic and semi-synthetic ATFs, most factory fills are petroleum based and that is what the carmakers suggest when changing the fluid. Obviously, this is asking a lot from one fluid, and it can be overworked to the breaking point.

Heat is ATF enemy No. ATF is supposed to get no hotter than degrees Fahrenheit. At this temperature, it can last , miles with no sweat. But, for every 20 or so degrees more heat, the oxidation rate doubles. Where does heat come from? Spinning your wheels--and shifting back and forth--in snow heats the fluid rapidly. And since the car is not moving, little air is flowing through the radiator, which houses the transmission fluid cooler.

Pulling a trailer also stresses the transmission fluid by raising its temperature. Oxidized fluid has an acrid odor that some say smells like burnt toast. Remove your dipstick and take a whiff. Look for varnish on the stick. Put a drop of the ATF on a white paper towel and, after a minute, see whether the fluid appears tan instead of red.

Sludge, varnish and acids form when the fluid oxidizes. That is why ATF should be checked and changed at least as often as prescribed in your owner's manual. Returning to the question, we think it would be safe to change the fluid because it has good color, and the transmission is behaving normally.

But most car owners request an ATF change only when they feel a problem. Changing the fluid in these cases usually makes matters worse. Generally, if the transmission fluid has not been changed around 60, miles, varnish and sludge from oxidized fluid combine with particles from clutch and band wear and create a gummy--almost solid--goo that sticks to transmission parts. When you change the fluid, the new ATF acts like a solvent to loosen this junk.

Like sand, it can wear the friction materials off the bands and clutches causing slippage. Valves--and there are lots of them in the transmission--get stuck open or closed. This causes slow engagement or slippage. Once the buildup is removed, leaks that it prevented begin from seals and gaskets. Any oxidized fluid left behind makes the new fluid more prone to breakdown. But fresh fluid will not provide more "bite" and cause accelerated wear. The amount of bite depends on the friction modifiers added to the fluid.

ATF without friction modifiers allows less slippage in clutch and band engagement, causing harsh shifts. Changing the transmission fluid on a high-mileage car is risky. Don't do it unless your transmission is running fine and the fluid is first-rate, because it can make transmission failure imminent. Some shops will not change the automatic transmission fluid on high-mileage cars due to the risk of problems arising after the service.

Jim D. Stokes, manager of technical services for Pennzoil, a leading supplier of ATF, issued a service bulletin advising shops about the risk.

Included with the advisory is this sample waiver:.
