The transmission works with your engine to move your Nissan. The engine produces energy, which is focused by the transmission using a range of gears to deliver the correct amount of power to the wheels to allow them to move at the required speed. As your Nissan dealer, we want to advise you on a few signs that you need to visit us for a transmission service.
Leaking Fluid
The transmission can’t function without fluid. Transmission fluid provides the essential hydraulic power that enables the transmission to smoothly shift gears. The constantly moving fluid protects numerous components by coating them with a friction-resistant covering, which protects them against damage. In addition, the fluid helps cool the hot components.
A transmission leak is typically easy to spot, as transmission fluid is bright or dark red. If you don’t spot a leak, you’ll notice its effects as you’ll hear strange noises from the transmission, shifting will be delayed, and the check engine light will illuminate. Our technicians will investigate, starting with checking the transmission pan gasket, the main potential site of a leak. Once the leak is sealed, we’ll refill the fluid.
Delayed Shifting
When the transmission shifts gears, the original gear disengages, and the new gear engages effortlessly and silently. Delayed shifting occurs when there’s a noticeable gap between the gears disengaging and engaging. Your tachometer will show a higher-than-expected RPM count, and you’ll hear a straining sound from your engine.
The shifting delay is almost unnoticeable when it starts but will rapidly worsen if not repaired. The usual cause of this issue is low transmission fluid, but it could also be caused by a blocked transmission filter, worn gears, or a fault with the transmission computer. We’ll need to examine the transmission to identify the problem, then we’ll fix it.
Humming, Buzzing, and Whining
A healthy transmission makes no sound as the gears shift, so any sound when shifting means something isn’t working correctly. This type of issue usually starts with a faint humming or buzzing noise, which gradually rises in intensity and can shift into a high-pitched whining noise. If you hear any transmission noises, contact us right away so we can investigate.
These sounds can have various causes. Low transmission fluid is a possibility, but dirty or contaminated fluid, a worn shaft or bearing, or a damaged torque converter could all produce these sounds. We’ll identify and repair the problem, and the sounds will cease. Driving with a worn or damaged transmission can cause it to fail and sustain irreversible damage in the process. If you have a transmission issue, contact us ASAP at Ken Ganley Nissan Mayfield in Mayfield Heights, OH.
