Automatic Transmission Noises: What They Mean and How to Fix Them

If you’re experiencing strange noises coming from your automatic transmission, it’s important to have it checked out by a qualified mechanic as soon as possible. Ignoring transmission problems can lead to more serious (and expensive) repairs down the road.

Here are some of the most common automatic transmission noises and what they might mean:

Whining or humming noise

A whining or humming noise is often a sign of low transmission fluid. Checking the fluid level is a simple and inexpensive way to rule out this potential cause. If the fluid level is low, add more of the recommended type of fluid and see if the noise goes away.

If adding fluid doesn’t solve the problem, the whining or humming noise could be caused by a worn-out bearing or gear. These repairs are more complex and expensive, so it’s important to have the transmission inspected by a mechanic as soon as possible.

Clunking or grinding noise

A clunking or grinding noise is often a sign of a more serious transmission problem, such as a broken gear or a damaged torque converter. These repairs can be very expensive, so it’s important to have the transmission inspected by a mechanic as soon as possible.

In some cases, a clunking or grinding noise can be caused by a simple problem, such as a loose driveshaft or a worn-out U-joint. These repairs are less expensive than repairing a broken gear or a damaged torque converter, but it’s still important to have the problem diagnosed by a mechanic.

Slipping or jerking noise

A slipping or jerking noise is often a sign of a worn-out transmission clutch. This repair can be expensive, but it’s important to have it done as soon as possible to prevent further damage to the transmission.

In some cases, a slipping or jerking noise can be caused by a simple problem, such as a clogged transmission filter. This repair is less expensive than replacing a worn-out clutch, but it’s still important to have the problem diagnosed by a mechanic.

Buzzing or rattling noise

A buzzing or rattling noise is often a sign of a loose or damaged transmission mount. This repair is relatively inexpensive, but it’s important to have it done as soon as possible to prevent further damage to the transmission.

In some cases, a buzzing or rattling noise can be caused by a simple problem, such as a loose exhaust system. This repair is less expensive than replacing a damaged transmission mount, but it’s still important to have the problem diagnosed by a mechanic.

How to prevent automatic transmission problems

There are a few things you can do to help prevent automatic transmission problems:
