The transmission is a hardy system, designed to work continually at high speed and temperatures to transfer the engine’s energy to the wheels. Despite its toughness, it requires regular servicing. As your Nissan dealership, we want you to know some signs you need to visit us for a transmission service.
Leaking Fluid
Transmission components move at high speed, generating heat. Transmission fluid circulates through the system to cool these components. It covers them in a friction-resistant coating, allowing them to move smoothly while protecting against wear and tear. Additionally, the fluid supplies the hydraulic power that enables the gears to shift as needed.
Old, worn seals can shrink, allowing transmission fluid to leak. As fluid is lost, the remaining transmission fluid slows down, and the transmission becomes less responsive. You may also hear noises when the gears change. The temperature inside the transmission will rise, and this can cause additional damage. We can repair any leak and test the transmission to ensure it’s in good condition.
Humming, Buzzing, or Whining
Strange noises from the transmission are always a sign that something is wrong, as a healthy transmission shifts gears very quietly. Noises usually start as a slight buzzing or humming just on the edge of hearing. As time passes, the noise will grow louder and can change to a high-pitched whining sound. If you hear any sound from the transmission, we advise contacting us ASAP so our technicians can investigate.
The good news is that the quicker we can examine your transmission, the less chance there is that it will suffer damage. The main reason for noisy transmission is a lack of transmission fluid. This could be due to a leak, as we saw above, or a blockage in the transmission filter. Low fluid levels cause friction in the transmission, causing odd noises. Once the issue is repaired, the transmission will be silent again.
Check Engine Light
The check engine light illuminates to warn of any problem affecting engine performance. It will also light up if something is wrong with the transmission. The engine and transmission work closely together to move your vehicle. The engine provides energy, and the transmission harnesses this energy and transfers it through the gears to the wheels to enable them to move at the required speed.
If a problem develops in the transmission, the engine works harder to try to compensate. This increases wear and tear on engine components, and your vehicle’s computer will activate the warning light. We’ll examine the engine and transmission and repair the problem.
Most transmission issues can be quickly and inexpensively repaired if detected when they begin. Contact us today at All Star Nissan in Denham Springs, LA.
