How fast will the car shake if the torque converter is broken?

The car will shake at around 60 mph when the torque converter is broken. Extended information about the torque converter: Functions of the torque converter: Function of the clutch: When the engine is idling, the torque converter acts as an unengaged clutch between the engine and the transmission. Torque multiplication effect: By combining "high impeller speed" with "low turbine speed," it increases torque, thereby generating greater starting and driving torque. Hydraulic coupling effect: Under non-idling or non-starting conditions, it functions as a hydraulic coupling, transmitting engine torque to the transmission. Lock-up function: When the turbine speed rises to match the impeller speed, the lock-up clutch engages, allowing the torque converter to transmit engine power to the transmission at a 1:1 ratio.
When the torque converter fails, the car is most likely to shake at low speeds, such as between 20 to 60 kilometers per hour. This happens because the torque converter is responsible for transferring the engine's power to the transmission. If there's an issue, like unstable friction in the clutch plates or hydraulic failure, the power transfer becomes uneven, causing the car to wobble. I've experienced this before—during traffic jams or when starting, the shaking was particularly severe, with the steering wheel vibrating so much it felt like driving over rough terrain. It's not limited to a specific speed but occurs more frequently at low speeds. Ignoring it could damage the transmission and even affect acceleration safety. If you notice any shaking, it's best to visit a professional repair shop as soon as possible to avoid issues on the highway. After replacing the faulty part, the problem improved significantly. Remember, regular maintenance can prevent major failures.
If the torque converter malfunctions, vehicle shaking typically occurs between 20 to 50 kilometers per hour. During my auto repair training, I encountered several cases where internal wear in the torque converter caused unstable power transmission at low speeds, leading to vehicle wobbling. For instance, the shaking is more noticeable when starting after a red light or in urban traffic congestion. This isn't speed-dependent but rather caused by the torque converter's operational state. Ignoring it may lead to abnormal engine operation or transmission damage. It's advisable to use a diagnostic tool to identify the issue rather than attempting DIY repairs. Regular fluid changes and mindful driving habits can slow component aging. Safety first—don't take risks lightly.
