Checking Your Own Transmission Fluid
Ever notice reddish or pinkish oils or fluids collecting under your engine? It’s possible that was a transmission fluid leak. Checking and changing your transmission fluid is one of the many critical aspects of vehicle maintenance, and it’s something that should be done every 30,000 to 60,000 miles. Otherwise, you risk extremely expensive transmission repairs that might override the value of a cheaper car entirely.
Today we’re going to talk about what transmission fluid it is, signs that you need to change it, and where you can get that done if need be!
What Does Transmission Fluid Do?
Like most moving parts on an automobile, the transmission consists of a bunch of metal parts grinding against each other like some kind of hot robo-rave. Actually, the transmission is just a gear box full of moving gears that grate and rub against each other, and they would break quickly without lubricant. Transmission fluid is the lubricant for the gears in the transmission’s gearbox.
In vehicles with automatic transmission, transmission fluid also provides hydraulic pressure that enables internal components to operate. In both manual and automatic transmissions, it also helps reduce heat caused by friction between the gears, which aggravates wear and tear further.
Signs of Low Transmission Fluid
There are a number of signs that your transmission fluid is low including:
Red, pink or oddly tinted oils or fluids under your engine
Shifting gears is difficult or certain gears won’t engage at all
Shifting causes the vehicle to lurch or shake
Odds smells especially during shifting, likely of burning or smoke
Odd noises like whirring or humming, especially if you can feel it through gear stick
While it’s unfortunate to have these problems at all, fortunately they tend to be somewhat easy to identify so diagnosis isn’t usually too difficult. Not only that, with proper maintenance and auto repair service, it’s fairly easy to prevent this from happening at all. You can usually keep up on transmission fluid refills simply by asking if you should get one at the same time you get an oil change. If you go to the same auto shop, they often keep that information on file and you won’t even have to remember anything.
How to Check Your Own Transmission Fluid
Please have your vehicle owner’s manual at hand for this, as you may need it to reference where your transmission fluid dip stick is. Especially since some cars use transmission systems that are closed forever thus they do not have dipsticks, and you’re wasting your time looking for one. If that’s the case, you’d certainly want to know that beforehand, eh?
Here’s the gist of how to check your own transmission fluid:
Pop the hood (preferably by banging it with your fist if you’re cool enough)
Look for the transmission fluid dipstick.
Do not confuse this with the engine oil dipstick which you’re likely more familiar with. The transmission fluid stick is usually located farther back in the engine compartment near the windshield. Often it’s marked with a unique color or symbol so you know what it’s for.
Pull the transmission dipstick and wipe off the fluid. Look a the stick, there should be marks for “low”, “fill”, and/or “full”.
Remember them, they come up later. This is foreshadowing.
Put it back in all the way, without pushing too hard or shaking it around too much so you don’t get residual fluid on the stick and misread that there’s some in there when there’s not
Turn on your car and leave it idling
While the vehicle is idling, take the dipstick back out and look at the fluid to see where it lines up with the marks we remember from earlier. If the mark is at anything but the top “full” line, you need more transmission fluid.
Put the dipstick back in securely, and probably go ahead and turn off your car and close your hood if you’re done here.
Maybe go have a sandwich. You’ve earned it.
It’s a fairly simple process, just make sure you have a shop rag on hand so you don’t grease up that smartphone if you need to give us a service call. Here’s a backup guide from Car And Driver magazine’s website, but it’s less detailed and not as fun as ours:
