Most drivers don’t think about their auto transmissions until a problem arises. And by then, the only fix may be a costly transmission rebuild or replacement. That’s why it’s so important to keep up with regular maintenance and to recognize the early signs that your transmission might need some TLC.

Like your vehicle’s engine, your transmission relies on sufficient lubrication to function at its best. When transmission fluid is low or in need of replacement, your car’s transmission can suffer increased friction and decreased efficiency. Left untreated, the problem can lead to transmission failure and a major repair bill.

So how can you know if you transmission fluid levels are low? Here are a few signs too watch for…

1.Problems Changing Gears

Whether your vehicle has an automatic or standard transmission, it should transition smoothly between gears. If you are experiencing stiff or laggy gear changes when accelerating or a “clunky” feeling when shifting, it’s time to check your transmission fluid levels. If your fluid levels are low or if your fluid has lost critical viscosity (slipperiness), you could be putting unneeded stress on your transmission’s many moving parts, resulting in sub-par performance. Topping off or replacing your fluid now could save you big bucks down the road.

2. Slip Sliding Away

Dos your transmission have trouble staying in gear, or does it seem to slip out of gear when you shift? The problem could be as simple as you transmission fluid levels. By checking you transmission fluid level using the dipstick provided, you can quickly assess whether low fluid is a problem. Also check the consistency of t he fluid. It should be clear, smooth and slippery, not dark, tacky or gritty.

3. What’s That Noise?

When operating at peak efficiency, your transmission should run quietly. So if you notice any unexplained grinding, scraping, clattering, or clunking sounds when shifting gears, the problem could be low fluid levels. Remember that the smooth operation of your transmission depends on adequate lubrication of its many moving parts. Fluid that’s low or degraded can cause unwanted friction and a “metal on metal” sound from your vehicle’s undercarriage. Replacing the fluid now could prevent larger, more expensive problems later on.

4. Overheating

Most transmissions operate best between 175ºF and 200ºF (slightly higher for heavy-duty haulers). Transmission fluid temperatures above 225ºF can cause your fluid to degrade, and can actually shorten the life of your transmission, even if it seems to be running fine now. If your transmission fluid has a burnt odor or seems thick or tacky, you may have an overheating problem. Not sure about your transmission temp? Ask a transmission expert to check it. If your trans runs consistently above optimal temps, ask a transmission specialist about adding an aftermarket transmission cooling system to your vehicle.

5. Leaks

It’s always a good idea to check your car for any fluids that might be leaking—whether it’s engine oil, antifreeze, or transmission fluid, leaks are a sure sign of a problem. A transmission fluid leak can rob your car’ trans of adequate lubrication and can shorten the overall life of your transmission. A transmission expert can locate and repair a fluid leak before it causes catastrophic damage to your vehicle.
