Okay, so how do you even know if your Nissan Murano's transmission is acting up? Here are some telltale signs to watch out for. Recognizing these early can save you a lot of headaches and money down the road.

• Slipping Gears: This is a big one. Imagine you're cruising along, and suddenly, the engine revs up, but your car doesn't accelerate as it should. It feels like the transmission is struggling to hold onto the gear. Gear slippage not only affects your car's performance but can also be a safety hazard, especially when you need to accelerate quickly in traffic. Ignoring this symptom can lead to further damage to the transmission, so it's crucial to address it promptly.
• Rough or Jerky Shifting: Instead of smooth, seamless gear changes, you feel a noticeable jolt or jerk when the transmission shifts. This can be especially noticeable at lower speeds. Rough shifting can make your daily commute uncomfortable and may indicate that the transmission fluid is low or contaminated, or that there are internal mechanical issues. Don't just brush it off as a minor annoyance; get it checked out to prevent more serious problems.
• Delayed Engagement: You put the car in drive or reverse, and there's a noticeable delay before it actually moves. It's like the transmission is thinking about it for a second (or longer!) before finally engaging. Delayed engagement can be frustrating and potentially dangerous, particularly when you need to maneuver quickly in parking lots or traffic. This symptom often points to issues with the transmission's internal components or low fluid levels, both of which require immediate attention.
• Unusual Noises: Whining, clunking, or humming sounds coming from under the car, especially during gear changes, can be a sign of transmission trouble. These unusual noises are often indicative of worn-out bearings, damaged gears, or other internal problems within the transmission. While some noises might seem minor at first, they can quickly escalate into more significant and costly repairs if left unaddressed. Pay close attention to any new or unusual sounds your car makes and consult a mechanic if you're concerned.
• Burning Smell: A burning odor, especially after driving for a while, could indicate that the transmission fluid is overheating. This is a serious sign that needs immediate attention. Overheated transmission fluid loses its ability to lubricate and cool the transmission's internal components, leading to increased wear and potential damage. The burning smell is a clear indicator that something is seriously wrong, and continuing to drive the car in this condition can result in catastrophic transmission failure.
• Check Engine Light: While the check engine light can come on for a variety of reasons, it could be related to a transmission problem. Get the code read to see if it's transmission-related. The check engine light is your car's way of telling you that something isn't right, and it's essential to take it seriously. If the diagnostic code indicates a transmission issue, it's crucial to have the problem diagnosed and repaired by a qualified mechanic as soon as possible to prevent further damage.
