Ford Automatic Transmissions Catalog

The torque converter plays a very important role in the Ford rebuilt automatic transmission. The Ford torque converter is responsible for multiplying the turning power provided by the engine. Fitted next to the engine crankshaft but not touching it is the transmission shaft. This metal rod, also called the input shaft, connects the torque converter to the motor. The engine turns the automatic transmission by hydraulic coupling in the torque converter using transmission fluid. On the inside of the torque converter there are a few other components as well that help multiply the power. They are the pump (or impeller), the turbine and the stator (also called guide wheel).

Inside the round metal casing the pump and the turbine face each other. The two components both have blades which catches the transmission fluid causing them to spin. The spinning of one fan causes the other to spin as well. The centrifugal force forces the fluid to move to the outside of the blades. Here, it gets redirected by the third fan - the stator, to the turbine side. The power which is multiplied is actually caused by this continual flow of fluid.

The fluid connection being the only link between the two sides of the torque converter; it is but natural that there would be a little slippage from about 2-5%. The Ford rebuilt automatic transmissions have a lockup clutch or the torque converter clutch to increase efficiency and gas mileage. Apart from this the automatic transmission has the planetary gear sets. These are circular, different sized gears revolving around a central gear known as the sun gear. Apart from the sun gear it has the planet carrier, drum and pistons and, the ring gear and drum. In the first gear the front planetary gear gets locked onto the input shaft which gets the car to move. Once the car starts rolling, the transmission shifts to the second. In this case the input shaft is locked to the ring fear. In the higher gear all planetary gear members are locked to each other and to the output shaft. The gear shifting in the Ford automatic transmission uses transmission bands. Fitted around the outside of the clutch housing is a flexible metal ring which tightens to engage the gears and loosens to release them. The automatic transmission turns the output shaft. The output shaft spins the axle which consequently makes the wheels go.

Our Ford rebuilt automatic transmissions are remanufactured to meet or exceed the manufacturer's original equipment specifications. Our rebuilt and remanufactured Ford automatic transmissions improve torque performance and provide more horsepower.
