I have a 2015 2.5 s altima with almost 120,000 miles that may have a bad transmission.... I don't know how to describe the noise. I first noticed the noise when I went down steep hills and my rpms rose to 3 and 3500. Now I hear the same noise ever time I back out of the garage. I took a video of it and showed it to a mechanic bc ofc it didnt want to make the noise for him, he said definitely doesn't sound good. But he doesnt understand why it would make that noise in reverse. It doesnt make sense bc normally faulty transmission make noise up hill when accelerating. He also noticed that my rpms fluctuate for no reason. He said it might be a glitch might need a software update. Does anyone else have this issue? Could anyone tell me what's wrong?
