Everything You Need to Know About Transmission Fluid Changes

Transmission fluid is (almost literally) the lifeblood of the transmission. An automatic transmission simply won’t work without transmission fluid. Now, you would have to have a very large leak to have absolutely no fluid in your transmission. However, you still need to have the right level and the right quality of transmission fluid or else you’re inviting transmission problems to happen. To have your transmission in perfect working order, you might require a transmission fluid change.

Transmission Fluid

Transmission fluid works as a lubricant and it is optimized for the functions of the transmission. These functions include valve operation, brake band friction, and the torque converter. Transmission fluid is required in all automatic transmissions. Some manual transmissions also use transmission fluid, but some use engine oil or gear oil.

Transmission Fluid Problems

Not all transmissions are the same; not even all automatic transmissions. But all transmissions experience wear and tear that can cause debris to collect in the fluid. Furthermore, there can be problems within transmissions that cause the fluid to be damaged or degraded, and this in turn can cause further problems.

And then there are leaks. Any transmission can fall foul of a leak. The key sign of a leak is a patch of reddish liquid that has collected underneath your vehicle as it is parked. Leaks have to be patched and the lost fluid needs to be topped up.

Symptoms of using Poor Quality Transmission Fluid

If the fluid in your transmission is lacking in either quantity or quality, you will begin to notice symptoms in how your transmission operates. You may experience a temporary delay while shifting gears. Your transmission may take a moment to register the gear shift. Your transmission might also grind or clunk when you shift. Alternately, your transmission might slip from one gear into another (usually neutral) which can be very dangerous. And without enough fluid, your transmission can become overheated.

Transmission Fluid Changes

You should periodically check your transmission levels using your dipstick. Sometimes you can lose some fluid without experiencing a leak. In this case, you can top of the transmission fluid yourself or you can bring it into a transmission shop for a top up.

Transmission fluid changes can sometimes be a bit more complicated. Typically a fluid change is required when the fluid has become degraded or burned. You might be able to tell this yourself. Normally, transmission fluid is translucent with a reddish hue. If your fluid is opaque and/or has a foul smell to it, it is probably damaged. Also, transmission fluid can pick up too much impure matter from wear and tear within your engine. If this is the case, it has probably been detected by a technician during a pan examination.

How Transmission Fluid Changes Work

You might be able to do a transmission fluid change on your own, depending on the type of transmission you have. But sometimes it is necessary (and always a lot easier) to bring it in to a transmission shop. Here, technicians can flush out the bad transmission fluid and change it with new, better quality fluid.

How and When Should I Change My Transmission Fluid?

How and When Should I Change My Transmission Fluid

Transmission fluid is the lifeblood of your transmission. Transmission fluid acts as a lubricant to help keep everything running smoothly and efficiently. That is, of course, assuming that you have good levels of clean transmission fluid in your transmission. To ensure this at all times, you should regularly change your transmission fluid. But how and when is sometimes a matter of debate.

Transmission fluid

There are many transmission problems that can be caused or exacerbated by an inadequate quantity or quality of transmission fluid. If you are driving around with either very old or not enough transmission fluid (or worse still, both), you are accelerating the wear and damage on components within your transmission. Taking the time to change it out when necessary could save you loads of time and money in the end by extending the lifespan of your transmission.

When to change your transmission fluid

Just when you should change out your transmission fluid will vary depending on what kind of transmission you have, what vehicle you drive, where you drive, how you drive, and how much your drive. But for a very rough estimate, for an automatic transmission, you ought to change your fluid every 50,000-100,000 kms. 100,000 kms is in the far reaches of the acceptable range, mind you. The Automatic Transmission Rebuilders Association suggests every 50,000 kms or every two years.

For manual transmissions, you should change the fluid about every 50,000-90,000 kms, however, under intense use, some manufacturers suggest changing it as often as every 25,000 kms. The reason for the difference between automatic and manual transmissions is because they take different fluids. Automatic transmissions take –get this– automatic transmission fluid. For manuals, it is a bit more complicated. They might take any of a variety of oils: regular motor oil, heavyweight hypoid gear oil, or even automatic transmission fluid in some cases. Your owner’s manual will tell you which is best for your transmission.

How to change your transmission fluid

To change out your transmission fluid, first let your car idle for a few minutes. After turning your ignition off, raise and secure the vehicle. Lay down at least a two-gallon catch pan, then carefully remove the bolts from one side of the transmission pan and then the other bolts, allowing the pan to tilt and drain. Once you’ve removed all the bolts, lower the pan and dump the remaining fluid into the catch pan.

After that, remove the old transmission filter and O-ring. The filter contains fluid, so keep the drain pan underneath. Install the new transmission filter, and make sure that the O-ring is in the appropriate place. Attach the new gasket to the pan with oil-soluble grease – not gasket sealer or adhesive.

Screw in all the fasteners finger-tight. Torque the pan bolts to spec in a spiral pattern starting at the center. Maximum torque is often about 12 pounds per foot. Then, lower your automobile and fill the transmission with the recommended amount of fluid. Finally, turn your engine on to check for leaks.
