Checking the transmission fluid in your 2015 Nissan Murano is a fundamental aspect of vehicle maintenance that is often overlooked. This specific procedure is critical for the longevity and smooth operation of the continuously variable transmission (CVT), which is standard across the Murano lineup. Neglecting this fluid can lead to increased wear, reduced fuel efficiency, and potentially costly repairs down the line.
Understanding the 2015 Murano's Transmission System
The 2015 model year Nissan Murano utilizes a sophisticated Continuously Variable Transmission (CVT) paired with the VQ35DE 3.5-liter V6 engine. Unlike traditional automatic transmissions with fixed gear ratios, a CVT uses a belt and pulley system to provide an infinite range of gear ratios. This design optimizes power delivery and fuel economy but requires the correct fluid viscosity and level to function properly. Using the wrong fluid or allowing the level to drop can severely impact the performance and durability of this system.
Signs Your Transmission Fluid Needs Attention
Before diving into the check procedure, it is essential to recognize the warning signs of low or degraded fluid. Owners should be vigilant for specific symptoms that indicate immediate attention is required. Ignoring these signs can lead to premature transmission failure and unsafe driving conditions.
Slipping or hesitation during acceleration.
Unusual noises such as whining, clunking, or grinding, particularly when shifting.
Delayed engagement when shifting from Park to Drive.
Visible signs of fluid leakage underneath the vehicle.
Check engine or transmission warning lights illuminating on the dashboard.
Preparation and Safety Protocols
Safety is paramount when performing any maintenance under the vehicle. To check the transmission fluid accurately, the engine must be at operating temperature and the vehicle must be positioned on a level surface. This ensures the fluid is distributed correctly within the torque converter and hydraulic circuits, providing an true reading of the level.
Warm up the engine by driving for 10 to 15 minutes.
Park the vehicle on a flat, stable surface.
Engage the parking brake firmly to prevent any movement.
Open the hood and locate the transmission fluid dipstick, usually positioned near the rear of the engine bay.
Step-by-Step Fluid Check Procedure
Locating the dipstick for the 2015 Murano is the first step in the process. Once found, the procedure is straightforward but requires careful observation of the fluid's condition. The goal is to verify both the level and the quality of the fluid to ensure the transmission is operating optimally.
