Diagnosing Torque Converter Problems

Diagnosing Torque Converter Problems

Nathaniel ValentinOctober 07, 2020

One of the most important connections under the hood of any automatic vehicle is the one between the engine and the transmission, which is made possible by the torque converter. A torque converter is the component responsible for the transmission changing gears without the use of a clutch. Due to the critical nature of this piece of equipment, knowing what warning signs to look for can help with diagnosing torque converter problems before a faulty component can cause serious damage.

Vehicle Slipping and Shuddering

Vehicle slipping and shuddering occurs when the driver is attempting to put the car in gear and can feel it vibrating while trying to build up enough power. This can occur when first starting the vehicle up or when driving. Aside from the shaking, the engine may also suddenly change gear for no reason.

Engine Overheating

When an engine is overheating, it could be a symptom of a faulty torque converter. Engine overheating occurs when the engine is not able to efficiently transfer its power to the transmission, resulting in excess heat. This heat can be enough to damage or destroy engine and transmission parts if not properly repaired.

Increased Stall Speed

Another symptom of a faulty torque converter is for there to be an increase in the stall point. A stall point is the RPM at which an engine can transfer its energy to the transmission. If the component is damaged, it forces the transmission to take more time to engage the engine.

Strange Sounds

Any time you hear a strange sound from your engine should be cause for concern. If your torque converter is damaged, your engine may begin to make clicking or whirring noises. Though these sounds can be common when dealing with engines, being able to pinpoint where the noises are coming from should make diagnosing torque converter problems much easier.
