Why does my car make a sound when I put it in reverse?
When you select reverse, the straight-cut gears engage, their teeth make tiny little taps on one another, and you hear that whine. The whine gets higher the faster you go, because you’re increasing the frequency of those little taps.
What does a bad transmission bearing sound like?
A buzzing, clicking, humming, roaring noise from inside the transmission is usually a symptom of a bad bearing, planetary gears damage, or other internal problem.
What does a transmission going out sound like?
Clunking, humming or whining sounds are signs of automatic transmission problems. Faulty manual transmissions will also give off loud machinelike sounds that seem to come out of nowhere. A clunking noise when you shift gears is a telltale transmission situation.

What happens if your transmission fluid is dirty?

When should you not change transmission fluid?
The manufacturer’s maintenance schedule for many automatic transmissions doesn’t call for fresh fluid until 100,000 miles or, with some Ford transmissions, even 150,000 miles. A lot of mechanics say that is too long and that it should be done at least every 50,000 miles.
What happens if you never change your transmission fluid?
If you don’t change your transmission fluid frequently, the dirty fluid will not serve as an effective lubricant and it won’t disperse heat well. This will cause wear and tear on the clutches and other parts of your transmission.
