Yes, some vehicles with automatic transmissions have a torque converter lockup.
Torque converter lockup
The torque converter connects the engine to the transmission and transfers power to the fluid. During lockup, the torque converter lockup clutch engages, connecting the torque converter input and output shafts. This eliminates slippage and creates a direct mechanical connection between the engine and transmission.
Advantages of torque converter lock-up:
* Improved Fuel Economy: Reduced torque converter slip losses save fuel.
*Increased performance: Direct mechanical coupling provides faster power transfer and improved acceleration.
* Reduced Transmission Heat: Eliminating slippage reduces transmission heat.
When the torque converter lockup is activated:
The torque converter lockup will typically engage under the following conditions:
*At constant speed
*At certain engine speeds
* When there is sufficient load on the transmission
Vehicles with torque converter lock-up:
Torque converter lockup is common in modern automatic transmission vehicles, including:
* Passenger cars
* SUVs
* Trucks
* Minibuses
