Your Nissan transmission is a very complex piece of engineering. It takes the raw power generated by your engine and uses a series of gears of decreasing sizes to transfer this power to your wheels to allow them to move. In time, your transmission can show signs of wear or damage, and you’ll need transmission repair at your San Jose Nissan dealership. These are some signs that your transmission could be in trouble.
Strange Noises
A Nissan transmission is almost completely silent as it works, which means any transmission noise is a sign of trouble. When this type of problem starts, the sounds are almost indistinguishable and easy to miss. As the problem progresses, noises will become louder and more noticeable. You’ll usually hear a slight buzzing sound that will eventually give way to a humming or whining noise.
One of the main causes of this problem is a transmission fluid leak. Transmission fluid plays many roles in the transmission, including friction protection for many transmission components and cooling the heat in the transmission. Its other vital function is to provide the hydraulic power that allows the transmission gears to shift. A lack of fluid will cause noises as the transmission components suffer damage.
Slipping Transmission
Your transmission shifts gears according to the dictates of your transmission computer. Once a gear has shifted, it should only shift again if the transmission shifts it or you manually override the gears. A slipping transmission is a situation where there’s a delay between the gear shifting and the new gear engaging.
Common signs of this problem include a burning smell when the gears shift, loud engine noises, your engine revving higher than it should, or an illuminated check engine light. A slipping transmission can be caused by a lack of transmission fluid or a problem with the gears, solenoids, or torque converter. We’ll examine your transmission and fix the problem.
Burning Smells
Strange smells from your engine are never a good sign. If you smell a foul burning rubber stench, you could have a transmission problem. As we’ve seen, transmission fluid is essential for your transmission. This fluid provides numerous benefits for the transmission, but it slowly accumulates dirt and other debris and needs to be changed regularly according to the schedule in your car manual.
Older transmission fluid becomes less effective at protecting transmission components and cooling the transmission, and the hydraulic power it generates decreases. In addition, older fluid loses its heat resistance. This can cause the fluid to overheat and burn, and you’ll smell burning rubber. We will drain your transmission, flush the remnants of the old fluid, and then refill it with fresh transmission fluid.
Transmission problems are usually quick and easy to repair if they’re detected and fixed when they appear. Call our service department today at Stevens Creek Nissan of Santa Clara, CA.
