Featured GEO Automatic Transmissions

In the case of GEO front wheel three-speed automatic transmission, the first gear delivers maximum torque and minimum speed for starting. The third gear allows maximum speed with minimum torque. Through a pair of reduction gear sets, the first gear coordinates the engine power to the drive wheels. This enables it to give increased power and reduced wheel speed when the car first begins to move. At this point in time the engine turns much faster than the output shaft, at around a 4:1 ratio. To obtain intermediate speeds the gear ratio is brought closer to 1:1.

The GEO rebuilt automatic transmission allows the gear ratio to be adjusted. To negotiate each driving situation, the automatic transmission provides the means of changing the ratio between the driving wheel rpm and the engine rpm. The GEO automatic transmission is encompassed in the drive train of the car. The major function of the drive train is to transmit power from the engine to the drive wheels and to vary the amount of torque. The planetary gear sets provide the various forward gear ratios as well as reverse. A special transmission fluid sent by the oil pump is utilized by the hydraulic system to control the clutches and the bands so that the planetary gear sets can be controlled.

To stop the car in gear while the engine is still running is done with the help of the torque converter. It is composed of three internal elements that work together to transmit power to the transmission. The pump, the turbine, and the stator make the three elements of the torque converter. Inside the round metal casing the pump and the turbine face each other. 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 governor and the modulator monitor the speed and throttle position in order to establish when to shift.

We offer the best rebuilt GEO automatic transmissions at cost effective prices. It is our endeavor to provide quality rebuilt automatic transmissions at affordable prices so that the trust of our customers is reposed in us. Our customer care representatives are as pleased to take your calls post sales as they are before making the sale.
