If you don’t know or can’t remember the last time it was changed or serviced this would be the place to start. Make sure you take a look at the fluid before you do anything with your transmission. This can lead to a feeling of extra slipping and chattering at speed. If the transmission fluid is dirty and old it won’t be able to do its job as a hydraulic fluid as well. This is one of the most common causes of torque converter problems. This will in turn cause the transmission to overheat. If there isn’t enough it can’t do its job. Transmission fluid is the lifeblood of the transmission and the torque converter bolted to it. There are many different things that can cause your Traverse to have torque converter problems. It can tell you a lot about the health of your transmission in general.Ĭauses of Torque Converter Problems: Chevy Traverse Taking a look at the transmission fluid should be the first thing that you do. If your Traverse has bad transmission fluid, it can cause the torque converter to go bad. This fluid helps cool the converter and transfers energy. Like your automatic transmission, the torque converter is full of transmission fluid. The best way to describe the sound would be a whir sound if you have bad bearings in it and a clunking sound if it’s a bad turbine fin. This shudder feels like a manual transmission when you need to downshift.Ī bad torque converter will often make strange sounds. If the torque converter fails to unlock at lower speeds, it shudders. It won’t do this at lower speeds so your Traverse can take advantage of the torque multiplication that a torque converter provides. Torque converters use a lock up clutch to create a true 1:1 connection between the engine and the wheels. When this happens, your torque converter has a higher effective stall speed. This keeps your Traverse’s engine from turning at the right RPM for any given speed, which can really hurt fuel economy. If the torque converter has gone bad, then it’s no longer transferring power to your Traverse’s rear wheels in an efficient manner. This increases the fuel mileage achieved and brings an automatic transmissions efficiency more in line with a standard transmission. This eliminates operating inefficiency when it is at high speed (usually after about 45 miles an hour). A locking converter has clutches in it that lets the transmission make a physical connection with the engine. Nearly all modern automatic transmissions have a locking torque converter. More Info: Traverse Transmission Slipping Diagnosis If you suspect this is happening with your car, has your fuel mileage changed? This is often a sign that the transmission isn’t operating efficiently. When a torque converter is malfunctioning it can cause this stall speed to change and feel like the transmission is slipping. The torque converter “stall speed” is the speed that the engine needs to be turning before the torque converter will begin engaging the transmission. Here are some of the most common bad torque converter symptoms that could happen to your Traverse. Symptoms of a bad torque converter include a vibration, too much RPM on the highway, and slipping.īad Torque Converter Symptoms: Chevy Traverse In the Chevy Traverse, a bad torque converter is often caused by bad transmission fluid, worn clutches, bad seals, or loose bolts. Your Chevy Traverse’s torque converter is responsible for converting the energy generated by the engine at the flywheel and transferring it to the transmission, creating a bridge between the engine and the transmission.
