What does it mean when your transmission is humming?
Humming is usually an indication that there is bearing going bad in your transmission, but can also be confused with carrier bearings and wheel bearings so make sure to check all those bearings before jumping to conclusions. Clunking or rattling in any system in your car usually means something either has or will soon fail catastrophically.
Why does my car make a humming noise when I push the accelerator?
Keep your foot off the brake pedal. Push the accelerator pedal, gently raising the engine rpm. If you notice a humming noise that increases in intensity as the engine rises in speed, it points to a malfunctioning transmission pump or pump shaft.
What does it mean when your transmission slams into gear?
When your transmission slams into gear it can be a sign of abnormal pressures, worn components or even a low fluid level. Start by checking your transmission fluid level and condition on the dipstick. If you find a low fluid level, ad BlueDevil Transmission Sealer and top off the fluid to get things back to normal.
What kind of noises do you hear when you shift gears?
Use some fast acceleration, allowing the transmission to firmly shift. Listen for any rumbling, growling or mechanical metal-to-to metal noise in each gear just after it shifts. Such noises indicate problems with the individual planetary gears, input shaft or interior transmission bearings.

Why is my transmission making a clunking noise?
Check the transmission cross member mount (rubber dampers) for excessive wear or splits. A noticeable vibration in the chassis frame during the heavy clunk will point more toward a defective transmission mount rather than a torque converter problem.
