Unlike other converters, Lockup Converters contain a clutch. When the clutch engages, it locks the engine to the transmission input shaft, providing a direct 1:1 drive ratio.

Torque converter lockup can have a major impact on how your engine performs. The torque converter is a part of the transmission, and you will notice that the engine will hesitate and be underpowered when it is locked up. How to insert lines in microsoft word document. There can be many different causes for certain engine problems.
- What Is Torque Converter Lockup? Transmission Center. Torque converters sit between the engine and transmission in automatics, their purpose described in the name-converting power from the motor to motion in the transmission. Modern converters.
- Correspondingly, can a automatic transmission lock up an engine? In a vehicle with an automatic transmission, the torque converter connects the power source to the load. Some of these devices are also equipped with a 'lockup' mechanism which rigidly binds the engine to the transmission when their speeds are nearly equal, to avoid slippage and a resulting loss of efficiency.
- Lockup torque converters were added to many newer-model vehicles to help with fuel economy. However, vibration problems can happen when these torque converters go bad. The vibration felt is known as 'lockup shudder' and may occur due to a bad engine or transmission as well.
Why would you want a lockup converter?
Really, it comes down to fuel economy. Lockup torque converters became popular when automakers were stuck in a Catch-22:

- Car buyers prefer automatic transmissions.
- Automatic transmissions are not as fuel efficient as manual transmissions.
- Automakers are required to meet government-mandated fuel economy targets.
Overdrive was one step toward better fuel economy with an automatic transmission. It allows the engine to turn at a lower RPM when the vehicle is traveling at higher speeds.
Torque Converter Lockup Controller
However, when the engine turns more slowly it causes the torque converter to slip, creating heat. Slipping reduces fuel economy and heat can damage the converter and the transmission. The solution is to lock the converter. Lock-up eliminates the slippage, which reduces heat and improves fuel economy.
