Common Transmission Problems And How To Fix Them

Vehicles are intricate machines. If one thing goes wrong, the entire vehicle can break down and become unusable. The transmission of a car is full of many moving parts (any of which can break at any moment), especially if the vehicle is not appropriately maintained. A broken transmission can cost hundreds of dollars to repair. 

Here is some information on common transmission problems and how to fix them.


Both automatic and manual transmissions can exhibit noises when there is a mechanical issue. An automatic transmission will make a clunking, whining, or humming sound. A manual transmission will make loud, mechanical sounds. With those types of noises, the source of the problem is likely the torque converter or the planetary gears. 

A car service can help fix those parts, whether they need maintenance or replacement. If you do not take your vehicle to a transmission repair service, it is very possible you will eventually need to replace the entire transmission.

Burning Smell

Because the transmission has many moving bits and pieces, it needs to be adequately lubricated. If the transmission fluid gets low, the moving parts will begin to break down and grind against each other. The friction will cause a buildup of sludge and debris. 

As you put miles on your vehicle, the fluid gets lower and dirtier. It will need to be cleaned, topped off, or replaced. If you smell a burning odor, it means the transmission fluid is too low. To fix this problem, first, determine the source of the low fluid. Is there a leak in the hose? Does the fluid just need to be refilled? A repair shop will know how to find the source of the problem and fix it immediately. Take your car to a mechanic to prevent long-term damage.

Gear Slipping

Issues can happen when changing gears, making you lose traction while driving. This feels similar to sliding on ice. With cars, less control is never safe, so it is not recommended to continue driving when you have a slipping transmission. 

Some ways to know your gears are slipping include revving occurring while you change gears, a delay in acceleration, and any other odd noises or resistance when trying to switch from gear to gear. This means there is an issue with your car's computer, which communicates with your transmission to control the gear switches and how much power is sent to your wheels. If you are concerned about a slipping transmission, stop using your car and contact a professional. Your mechanic will need to fix the computer to ensure the signals are properly being sent and connected.

No matter what concerns you may have with your transmission, a quality car mechanic can help you find the specific problems and get you driving on your way. Contact a local transmission repair service to learn more.
