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. A buzzing could also come from a bad internal sealing surface, a seal, or low transmission fluid due to a leak.
What does a bad bearing in a transmission sound like?
Often, bad automatic transmissions will emit humming, buzzing, or whining sounds; manual transmissions emit harsher mechanical noises, such as clunking. Some of these noises may relate to the engine, exhaust system, drive shaft, differentials or even a wheel bearing.
How much does it cost to replace a transmission bearing?
The average cost for carrier bearing replacement is between $286 and $372. Labor costs are estimated between $132 and $166 while parts are priced between $154 and $205. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.
What causes transmission bearings to go bad?
According to a recent study, up to 80 percent of bearing failures are caused by improper lubrication. This includes insufficient lubrication, use of improper lubricants or excessive temperatures that degrade the lubricant.
What does a transmission bearing do?

What is the most common cause of bearing failure?
The majority of bearing failures occur because of improper lubrication. Lubrication failure can occur if the wrong lubricant is used, if not enough lubricant is applied, or if the bearing has been exposed to excessive temperatures that have caused the lubricant to degrade. Corrosion & Contamination.
How do you check the condition of a bearing?
In the case of small non-separable ball bearings, hold the bearing horizontally in one hand, and then rotate the outer ring to confirm that it turns smoothly. Separable bearings such as tapered roller bearings may be checked by individually examining their rolling elements and the outer ring raceway.
Why is my transmission making noise?
Gurgling sounds from the transmission usually indicate that there is a problem with the levels of the transmission fluid. The noise is a result of excessive air in the transmission lines. The problem may develop if there is a transmission leak or when you forget to check the level of the transmission fluid.
Does an automatic transmission have bearings?
Automatic transmissions don’t use a pilot bearing in the rear of the crankshaft like a manual transmission does but there are bushings inside of the transmission that perform exactly the same function. The tourque converter has a centering pilot that lines it up with the crankshaft.
