Our Tucson Mechanics Answer FAQs about Transmission Fluid

For optimal transmission function, it’s very important that you’re operating with the proper amount of clean transmission fluid. If your transmission fluid becomes polluted, it should be promptly exchanged. At Atlas Transmission, we provide expert transmission service in the greater Tucson, AZ area. Here are some of the common questions regarding transmission fluid.
What does transmission fluid do?
Transmission fluid has a number of important tasks. It lubricates gears/clutch packs, prevents rust, and helps to keep the transmission from getting too hot. It also supplies the necessary fluid pressure for successful gearbox operation.
What are some common problems with transmission fluid?
One common sign of contaminated transmission fluid is that your car suddenly jumps out of gear while you’re driving. This may occur if pollutants build up in the fluid to the point that they obstruct the fluid’s flow. Consequently, fluid pressure drops to the point that the car doesn’t stay reliably in gear. Another common problem is that transmission fluid has started leaking. Such leaks often form due to cracked transmission lines and faulty transmission pan gaskets. A sign that transmission fluid is leaking is that there’s reddish-colored fluid on the pavement underneath your car. If the leaking fluid has a somewhat sweet scent, then you have further evidence that it is transmission fluid. To prevent major problems, transmission fluid leaks should be fixed ASAP.
How frequently should I check transmission fluid?
Transmission fluid should be checked once per month, even if you don’t have reason to believe that there’s a problem with it. By regularly checking the fluid, it’s far more likely that you’ll notice early if the fluid is getting too low and/or starting to burn. Transmission fluid is generally best checked with the car still on.
How often should I get my transmission fluid exchanged?
In many cases, transmission fluid is supposed to be exchanged somewhere between 30,000 and 60,000 miles. However, you should consult your owner’s manual to see your vehicle’s exact mileage point for this service and then always follow that specification.
