By shifting gears, a car transmission sends power to the wheels, allowing motorists to drive at different speeds. Poor driving habits and a lack of maintenance will cause the auto part to malfunction. Here’s what you need to know about identifying and preventing transmission failure.

The Symptoms of a Failing Transmission

The fluid lubricates the transmission’s mechanical components and acts as a coolant in automatic systems. Without it, the part will experience premature wear and fail. If this car part overheats, you’ll notice a burning smell as you drive.

When changing gears, be on alert for a grinding sound, vibrating sensation, or shifting problems. These issues indicate that the transmission synchronizer needs to be replaced. The auto part synchronizes speeds between the gears and collars. Continuing to drive with a bad synchronizer will cause additional strain on transmission parts and eventual failure.

Get in the habit of looking for unusual liquid spots where you park the car. The strange puddles may be caused by leaky auto parts. A reddish residue may be caused by transmission fluid seeping from corroded seals, a loose drain plug, or pan puncture.

How to Prevent Transmission Failure

Sticking to a regular maintenance schedule is the best way to prevent failure. Technicians will tighten loose components, replace worn seals, restore fluid levels, and perform other tasks to extend the auto part’s life span.

Changing the fluid in a manual model every 30,000 to 60,000 miles will prevent contamination from gear, synchronizer, and bearing particles. When the liquid is full of metal fragments, it can’t lubricate mechanical components. The fluid in automatic transmissions should be changed every 60,000 to 100,000 miles. When the liquid is clean, it’ll keep the transmission cool, so it doesn’t overheat.

Always put the car in park before engaging the parking brake—this will limit stress on the transmission. You should also come to a complete stop before shifting into reverse and drive, as the auto part isn’t designed to make a smooth transition while the vehicle is in motion.
