Everything You Need to Know About Transmission Fluid Changes (But Were Afraid to Ask)

Transmission fluid: it’s important. If you drive a vehicle with an automatic transmission, your vehicle won’t work without automatic transmission fluid. Manual transmission vehicles can also use transmission fluid as well but can also use something called transmission oil. Regardless, the principle is much the same. You need transmission fluid to operate your vehicle. But your transmission fluid will need changing occasionally. How do you know when that is? This article will go over everything you need to know about transmission fluid changes (but were afraid to ask).

Transmission Fluid

Without transmission fluid, you’ll have nothing to lubricate the various components within your transmission. The transmission is not one solid unit but rather a piece of machinery that is comprised of many constituent parts. All those parts need to be working together just so in order for the transmission to operate properly. What’s more, things can get hot under that hood, so transmission fluid is key because it can help cool everything down. There is no transmission problem in the world that cannot be caused or at least exacerbated by a lack of transmission fluid. But it’s not just quantity. Degraded transmission fluid can also cause serious problems for your transmission.

How Often Do I Need To Check My Transmission Fluid?

You should check your transmission fluid every month. Using the dipstick under your vehicle’s hood, check your transmission fluid levels and if they’re not where they should be, top them up. If you find yourself topping up your fluid levels every month, you’ve got a problem. You either have a leak or your transmission is somehow evaporating your fluid at a quick pace. Check under your vehicle after you’ve been parked for a while to see if any transmission fluid is leaking. If you have a leak or can’t pinpoint the problem, bring your vehicle into a mister transmission shop where it can be inspected by technicians.

What Should Transmission Fluid Look Like?

Transmission fluid in good working order should be largely translucent with a reddish hue. If it is opaque, then the fluid has been damaged or degraded. If the fluid is foul smelling or smells of burning, this is indicative of a transmission problem.

How Often Do I Need To Change My Transmission Fluid?

This is perhaps the most common question when it comes to transmission fluid. How often are transmission fluid changes required? Well, if you notice your transmission fluid is damaged, you have to change it. But this will probably be after an inspection and any repairs have been conducted, so it’s likely this will be handled by a transmission technician. Barring any transmission problems, you should check your manufacturer’s guide to see how often they recommend changing your transmission fluid, because it can be different for every vehicle. Broadly speaking, you should change your transmission fluid every 45,000-80,000 kilometers. Perhaps more frequently if you use your vehicle for towing.

Which Transmission Fluid Should I Use?

Again, check your owner’s manual to see what the manufacturer recommends. Often with automatic transmissions, a synthetic transmission fluid is best.

Zack Muise
I was givin a quote, not only by the staff here, but by many outside sources and they all gave me the same amount. So even though I had that expectation, they came in much less than half!! They could've charged me for the part and there'd be no reason to expect otherwise. They just did some cleaning on the needed part and that was enough. I appreciate the honesty and will recommend you guys forever.

My 9 1/2 year old Subaru developed a whirring noise and was brought to the dealerships attention within the 10 year warranty period. It wasn’t presented to me as a transmission problem until well after the warranty had expired.Chris and his staff were able to confirm the problem promptly, giving me a welcome second opinion, and encouraged me to return to the dealership to pursue repair or replacement, since Mr. T doesn’t have parts for Subarus. Now, a full replacement is happening. Thank you to Chris and his team for giving me the confidence to request what was deserved.
