Modern Nissan transmissions are remarkably sophisticated, and the Xtronic CVT transmissions in certain Nissan models take things to a whole new level, even learning your habits to refine shifting performance. Whether your car uses a CVT or traditional automatic shift, you’ll need to keep it well lubricated and pay attention to symptoms of low fluid or other trouble. The technicians at your local Nissan dealership can carry out prompt transmission service to keep your shifting smooth and easy.
High-Pitched Whining Noises
Insufficient lubrication may cause your transmission to whine plaintively as fast-moving parts start to rub against each other. Worn-down gears could also generate whining, or worn-out belts or pulleys in a CVT system. If you hear whining or a similar humming noise, always check the fluid first; it might need a top up.
Awkward Grinding Sounds
Heavier grinding is the sound of damage occurring as malfunctioning parts interconnect roughly. It’s best to pull over if your gearbox is grinding. Once again, check the fluid. If grinding persists after you’ve replenished the fluid, consult a trusted technician.
Vibrations When Shifting
As you know from experience, Nissan transmissions are ordinarily smooth and blissfully quiet. You certainly shouldn’t feel jolts, shaking, or any kind of vibrations when changing gears. If you do, there’s a malfunction somewhere below you that needs attention.
Delayed or Slipping Gears
After producing relatively mild warnings of strange sounds and shakes, a problematic transmission could really begin to misbehave. At first, there might be a delay of a second or two before the new gear engages. And if the issue is particularly severe, gears could slip and change on their own. These problems may be accompanied by sudden loud engine revving.
Dripping Transmission Fluid
Transmission fluid is all-important for gearbox health. This highly durable liquid can last in great shape for 60,000 to 100,000 miles. But that doesn’t mean you shouldn’t inspect it frequently to ensure it’s at the right level and hasn’t started to burn or age prematurely.
The most urgent fault relating to transmission fluid is a leak. A cracked seal, line, or gasket could let the fluid escape, which means lubrication and hydraulic pressure are plummeting inside the gearbox. With a leak, you may see a reddish-brown liquid under your car, and you’ll soon notice the various problems outlined above.
