A torque converter is a fluid coupling that connects the engine to the transmission and is what allows an automatic transmission to function. The torque converter is what makes it possible for your car to shift gears without you having to do anything.
The torque converter contains a pump and a turbine. The pump is attached to the engine and the turbine is attached to the transmission. The pump creates a flow of fluid and the turbine converts this into mechanical energy.
The torque converter is filled with transmission fluid. When the engine is running, the pump creates a flow of fluid and the turbine spins. This spinning action creates torque that is transferred to the transmission.
The torque converter is an important part of the transmission and if it is not working properly, the transmission will not work properly. If the torque converter needs to be replaced, it is a good idea to take your car to a mechanic and have them do it.
The cost to replace a torque converter can vary depending on the make and model of your car. The average cost to replace a torque converter is between $500 and $1000.
