What does the torque converter do on a transmission?

Answer 1

A torque converter transmitts the torque from the engine to the autmatic transmission. It replaces a clutch.

It consists of two turbines in a hydraulic fluid, one driven by the engine and one attached to the transmission. As the engine turbine it driven it pushes fluid through the transmission turbine and moves it. Since they are not connected mechanically, the vehicle can be stopped with the engine driven turbine still turning and not stall.

Once a certain amount of power (flow) is put through the transmission turbine, it 'torque locks' and behaves like a solid mechanical drive.

The down side of torque converters is they are inefficient. There is slippage loss at low speeds and heat loss at all speeds.

Modern auto trannys have locking torque converters that act like a clutch to increase efficiency.

Answer 2

It's like a turbine,it spins up to as many rpm's(revolutions per minute) that your engine is capable.When the cintrificale force of the tranny fluid gets forced into the (veiens) of the transmision it provides extreme pressure into the clutches.When the clutches press against eachother it has no other way to do anything beside move the vehical.In the automatic 1st gear is reverse.Yeah they're tricky.Your torque converter holds up to 4quarts of fluid,dependind on the ci(cubic inches) of the engine and what not.

Answer 3

it is a fluid coupling device that connects the engine to the transmission, and hydraulically converts the torque from the engine to power that the transmission can use to propel the car.

Answer 4

It is the connection between the vehicle's engine and transmission in an automatic equipped vehicle. It enables the vehicle to remain stationary, while in gear. It mulitplies torque (hence its name) during acceleration, and on today's vehicles, has a lock up mechanism to mechanically "lock" the driving member, to the driven member in order to eliminate slippage, and maximize fuel economy. Hope this explains it well.

Answer 5

Torque Converter is one of the main component of the Automatic Trasmission System. Without torque converter you cant imagine the working of the Automatic transmission Sysytem.
